Learning and teaching notes:   

This case study is focused on the role of engineers to address the problem of plastic waste in the context of sustainable operations and circular business solutions. It involves a team of engineers developing a start-up aiming to tackle plastic waste by converting it into infrastructure components (such as plastic bricks). As plastic waste is a global problem, the case can be customised by instructors when specifying the region in which it is set. The case incorporates several components, including stakeholder mapping, empirical surveys, risk assessment and policy-making. This case study is particularly suitable for interdisciplinary teamwork, with students from different disciplines bringing their specialised knowledge.  

The case study asks students to research the data on how much plastic is produced and policies for the disposal of plastic, identify the regions most affected by plastic waste, develop a business plan for a circular business focused on transforming plastic waste into bricks and understand the risks of plastic production and waste as well as the risks of a business working with plastic waste. In this process, students gain an awareness of the societal context of plastic waste and the varying risks that different demographic categories are exposed to, as well as the role of engineers in contributing to the development of technologies for circular businesses. Students also get to apply their disciplinary knowledge to propose technical solutions to the problem of plastic waste. 

The case is presented in parts. Part one addresses the broader context of plastic waste and could be used in isolation, but parts two and three further develop and add complexity to the engineering-specific elements of the topic.

Part one: 

Plastic pollution is a major challenge. It is predicted that if current trends continue, by 2050 there will be 26 billion metric tons of plastic waste, and almost half of this is expected to be dumped in landfills and the environment (Guglielmi, 2017). As plastic waste grows at an increased speed, it kills millions of animals each year, contaminates fresh water sources and affects human health. Across the world, geographical regions are affected differently by plastic waste. In fact, developing countries are more affected by plastic waste than developed nations. Existing reports trace a link between poverty and plastic waste, making it a development problem. Africa, Asia and South America see immense quantities of plastic generated elsewhere being dumped on their territory.  At the moment, there are several policies in place targeting the production and disposal of plastic. Several of the policies active in developed regions such as the EU do not allow the disposal of plastic waste inside their own territorial boundaries, but allow it on outside territories.  

 

Optional STOP for activities and discussion 

 

Part two: 

Impressed by the magnitude of the problem of plastic waste faced today, together with a group of friends you met while studying engineering at the Technological University of the Future, you want to set up a green circular business. Circular business models aim to use and reuse materials for as long as possible, all while minimising waste. Your concern is to develop a sustainable technological solution to the problem of plastic waste. The vision for a circular economy for plastic rests on six key points (Ellen McArthur Foundation, n.d.): 

  1. Elimination of problematic or unnecessary plastic packaging through redesign, innovation, and new delivery models is a priority 
  2. Reuse models are applied where relevant, reducing the need for single-use packaging 
  3. All plastic packaging is 100% reusable, recyclable, or compostable 
  4. All plastic packaging is reused, recycled, or composted in practice 
  5. The use of plastic is fully decoupled from the consumption of finite resources 
  6. All plastic packaging is free of hazardous chemicals, and the health, safety, and rights of all people involved are respected 

 

Optional STOP for group activities and discussion 

 

Part three: 

The start-up SuperRecycling aims to develop infrastructure solutions by converting plastic waste into bricks. Your team of engineers is tasked to develop a risk assessment for the operations of the factory in which this process will take place. The start-up is set in a developing country of your choice that is greatly affected by plastic waste.

Learning and teaching notes: 

This case study provides students an opportunity to explore the role of hydrogen fuel in the aviation industry. Considerable investments have been made in researching and developing hydrogen as a potential clean and sustainable energy source, particularly for hydrogen-powered aircraft. Despite the potential for hydrogen to be a green and clean fuel there are lingering questions over the long-term sustainability of hydrogen and whether technological advancements can progress rapidly enough to significantly reduce global carbon dioxide emissions. The debate around this issue is rich with diverse perspectives and a variety of interests to consider. Through this case study, students will apply their engineering expertise to navigate this complex problem and examine the competing interests involved.  

This case is presented in parts, each focusing on a different sustainability issue, and with most parts incorporating technical content. Parts may be used in isolation, or may be used to build up the complexity of the case throughout a series of lessons.

Hydrogen fundamentals resources: 

We recommend encouraging the use of sources from a variety of stakeholders. Encourage students to find their own, but some examples are included below: 

 

Pre-Session Work: 

Students should be provided with an overview of the properties of hydrogen gas and the principles underlying the hydrogen economy: production, storage and transmission, and application. There are several free and available sources for this purpose (refer to the Hydrogen Fundamentals Resources above). 

 

Introduction 

“At Airbus, we believe hydrogen is one of the most promising decarbonisation technologies for aviation. This is why we consider hydrogen to be an important technology pathway to achieve our ambition of bringing a low-carbon commercial aircraft to market by 2035.” – Airbus, 2024 

As indicated in the industry quote above, hydrogen is a growing area of research interest for aviation companies to decarbonise their fleet. In this case study, you are put in the role of working as an engineering consultant and your customer is a multinational aerospace corporation. They are keen to meet their government issued targets of reducing carbon emissions to reach net zero by 2050 and your consultancy team has been tasked with assessing the feasibility of powering a zero-emission aircraft using hydrogen. The key areas your customer is interested in are: 

 

Part one: The aviation landscape 

Air travel connects the world, enabling affordable and reliable mass transportation between continents. Despite massive advances in technology and infrastructure to produce more efficient aircraft and reduce passenger fuel consumption, carbon emissions have doubled since 2019 and are equivalent to 2.5 % of global CO2 emissions.  

 

 

Your customer is interested in the feasibility of hydrogen for aviation fuel. However, there is a debate within the management team over the sustainability of hydrogen. As the lead engineering consultant, you must guide your customer in making an ethical and sustainable decision.  

Hydrogen is a potential energy carrier which has a high energy content, making it a promising fuel for aviation. Green hydrogen is produced from water and is therefore potentially very clean. However, globally most hydrogen is currently made from fossil fuels with an associated carbon footprint. Naturally occurring as a gas, the low volumetric density makes it difficult to transport and add complications with storage and transportation. 

 

 

Part two: Hydrogen production 

Hydrogen is naturally abundant but is often found combined with other elements in various forms such as hydrocarbons like methane (CH4) and water (H2O). Methods have been developed to extract hydrogen from these compounds. It is important to remember that hydrogen is an energy carrier and not an energy source; it must be generated from other primary energy sources (such as wind and solar) converting and storing energy in the form of hydrogen.  

 

 

The ideal scenario is to produce green hydrogen via electrolysis where water (H2O) is split using electricity into hydrogen (H2) and oxygen (O2). This makes green hydrogen potentially completely green and clean if the process uses electricity from renewable sources. The overall chemical reaction is shown below: 

However, the use of water—a critical resource—as a feedstock for green hydrogen, especially in aviation, raises significant ethical concerns. Your customer’s management team is divided on the potential impact of this practice on global water scarcity, which has been exacerbated by climate change. You have been tasked with assessing the feasibility of using green hydrogen in aviation for your client. Your customer has chosen their London to New York route (3,500 nmi), one of their most popular, as a test-case. 

 

 

Despite its potential for green production, globally the majority of hydrogen is currently produced from fossil fuels – termed grey hydrogen. One of your team members has proposed using grey hydrogen as an interim solution to bridge the transition to green hydrogen, in order for the company to start developing the required hydrogen-related infrastructure at airports. They argue that carbon capture and storage technology could be used to reduce carbon emissions from grey hydrogen while still achieving the goal of decarbonisation. Hydrogen from fossil fuels with an additional carbon capture step is known as blue hydrogen. 

However, this suggestion has sparked a heated debate within the management team. While acknowledging the potential to address the immediate concerns of generating enough hydrogen to establish the necessary infrastructure and procedures, many team members argued that it would be a contradictory approach. They highlighted the inherent contradiction of utilising fossil fuels, the primary driver of climate change, to achieve decarbonisation. They emphasised the importance of remaining consistent with the ultimate goal of transitioning away from fossil fuels altogether and reducing overall carbon emissions. Your expertise is now sought to weigh these options and advise the board on the best course of action. 

 

 

Part three: Hydrogen storage 

Despite an impressive gravimetric energy density (the energy stored per unit mass of fuel) hydrogen has the lowest gas density and the second-lowest boiling point of all known chemical fuels. These unique properties pose challenges for storage and transportation, particularly in the constrained spaces of an aircraft.  

 

 

As the lead engineering consultant, you have been tasked with providing expert advice on viable hydrogen storage options for aviation. Your customer has again chosen their London to New York route (3,500 nmi) as a test-case because it is one of their most popular, transatlantic routes. They want to know if hydrogen storage can be effectively managed for this route as it could set a precedent for wider adoption for their other long-haul flights. The plane journey from London to New York is estimated to require around 15,000 kg of hydrogen (or use the quantity estimated previously estimated in Part 2 – see Appendix for example).  

 

 

Part four: Emissions and environmental impact 

In Part four, we delve deeper into the environmental implications of using hydrogen as a fuel in aviation with a focus on emissions and their impacts across the lifecycle of a hydrogen plane. Aircraft can be powered using either direct combustion of hydrogen in gas turbines or by reacting hydrogen in a fuel cell to produce electricity that drives a propeller. As the lead engineering consultant, your customer has asked you to choose between hydrogen combustion in gas turbines or the reaction of hydrogen in fuel cells. The management team is divided on the environmental impacts of both methods, with some emphasising the technological readiness and efficiency of combustion and others advocating for the cleaner process of fuel cell reaction.  

 

 

Both combustion of hydrogen in an engine and reaction of hydrogen in a fuel cell will produce water as a by-product. The management team are concerned over the effect of using hydrogen on the formation of contrails. Contrails are clouds of water vapour produced by aircraft that have a potential contribution to global warming but the extent of their impact is uncertain.  

 

 

So far we have considered each aspect of the hydrogen debate in isolation. However, it is important to consider the overall environmental impact of these stages as a whole. Choices made at each stage of the hydrogen cycle – generation, storage, usage – will collectively impact the overall environmental impact and sustainability of using hydrogen as an aviation fuel and demonstrates how interconnected our decisions can be.  

 

 

Part five: Hydrogen aviation stakeholders 

Hydrogen aviation is an area with multiple stakeholders with conflicting priorities. Understanding the perspectives of these key players is important when considering the feasibility of hydrogen in the aviation sector.   

 

 

Your consultancy firm is hosting a debate for the aviation industry in order to help them make a decision around hydrogen-based technologies. You have invited representatives from consumer groups, the UK government, Environmental NGOs, airlines, and aircraft manufacturers.  

 

 

Stakeholder Key priorities and considerations
Airline & Aerospace Manufacturer 
  • Cost efficiency (fuel, labour, fleet maintenance) – recovering from pandemic. 
  • Passenger experience (commercial & freight). 
  • Develop & maintain global supply chains. 
  • Safety, compliance and operational reliability. 
  • Financial responsibility to employees and investors. 
  • Need government assurances before making big capital investments. 
UK Government 
  • Achieve net zero targets by 2050 
  • Promote economic growth and job creation (still recovering from pandemic). 
  • Fund research and innovation to put their country’s technology ahead. 
  • Fund renewable infrastructure to encourage industry investment. 
Environmental NGOs 
  • Long-term employment for aviation sector. 
  • Demand a sustainable future for aviation to ensure this – right now, not in 50 years. 
  • Standards and targets for industry and government and accountability if not met. 
  • Some NGOs support drastic cuts to flying. 
  • Want to raise public awareness over sustainability of flying. 
Consumer 
  • Environmentally aware (understand the need to reduce carbon emissions). 
  • Also benefit greatly from flying (tourism, commercial shipping, etc.). 
  • Safety and reliability of aircraft & processes. 
  • Cost effectiveness – want affordable service

Appendix: Example calculations 

There are multiple methods for approaching these calculations. The steps shown below are just one example for illustrative purposes.  

 

Part two: Hydrogen production 

Challenge: Estimate the volume of water required for a hydrogen-powered aircraft.   

Assumptions around the hydrogen production process, aircraft, and fuel requirement can be given to students or researched as a separate task. In this example we assume: 

 

Example estimation: 

1. Estimate the energy requirement for a mid-size jet 

No current hydrogen-fuelled aircraft exists, so we can use a kerosene-fuelled analogue. Existing aircraft that meet the requirements include the Boeing 767 or 747. The energy requirement is then: 

 

2. Estimate the hydrogen requirement 

Assuming a hydrogen plane has the same fuel requirement:

 

3. Estimate the volume of water required 

Assuming all hydrogen is produced from the electrolysis of water: 

Electrolysis reaction:

For this reaction, we know one mole of water produces one mole of hydrogen. We need to calculate the moles for 20,000 kg of hydrogen: 

 

 

 

With a 1:1 molar ratio, we can then calculate the mass of water: 

This assumes an electrolyser efficiency of 100%. Typical efficiency values are under 80%, which would yield: 

 

Challenge: Is it feasible to power the UK aviation fleet with water? 

 

The total energy requirement for UK aviation can be given to students or set as a research task.  

Estimation can follow a similar procedure to the above. 

Multiple methods for validating and assessing the feasibility of this quantity of water. For example, the UK daily water consumption is 14 billion litres. The water requirement estimated above is < 1 % of this total daily water consumption, a finding supported by FlyZero.  

 

Part three: Hydrogen storage 

Challenge: Is it feasible to store 20,000 kg of hydrogen in an aircraft? 

There are multiple methods of determining the feasibility of storage volume. As example is given below. 

 

1. Determining the storage volume 

The storage volume is dependent on the storage method used. Density values associated with different storage techniques can be research or given to students (included in Table 2). The storage volume required can be calculated from the mass of hydrogen and density of storage method, example in Table 2.  

Table 2: Energy densities of various hydrogen storage methods 

 

2. Determining available aircraft volume 

A straightforward method is to compare the available volume on an aircraft with the hydrogen storage volume required. Aircraft volumes can be given or researched by students. Examples: 

This assumes hydrogen tanks are integrated into an existing aircraft design. Liquid hydrogen can feasibly fit into an existing design, though actual volume will be larger due to space/constraint requirements and additional infrastructure (pipes, fittings, etc) for the tanks. Tank size can be compared to conventional kerosene tanks and a discussion encouraged over where in the plane hydrogen tanks would need to be (conventional liquid fuel storage is in the wings of aircraft, this is not possible for liquid storage tanks due to their shape and infrastructure storage is inside the fuselage). Another straightforward method for storage feasibility is modelling the hydrogen volume as a simple cylinder and comparing to the dimensions of a suitable aircraft.

Learning and teaching notes: 

Before engaging with the case study, learners should be familiar with the process of calculating embodied carbon and conducting a cost-benefit analysis. The case study is presented in three parts. In Part one, an ambitious urban revitalisation project is under development, and a project manager needs to find a balance between financial considerations and the urgent need for sustainable, low-embodied carbon construction. In Part two, the project being developed is located in a coastal area prone to climate change-related disasters. The team needs to ensure that the project is durable in the face of disasters and, at the same time, upholds sustainability principles. Lastly, in Part three, stakeholders involved in the two previous projects come together to identify potential synergies.

Real-world cases to explore:

 

Part one: 

In the heart of an urban revitalisation project, the company CityScape Builders is embarking on a transformational journey to convert a neglected area into a vibrant urban centre which will be named ReviveRise District. This urban centre will mostly be formed by tall buildings. 

Avery, the project manager at CityScape Builders, is under immense pressure to meet tight budget constraints and deadlines. Avery understands the project’s economic implications and the importance of delivering within the stipulated financial limits. However, the conflict arises when Rohan, a renowned environmental advocate and consultant, insists on prioritising sustainable construction practices to reduce the project’s embodied carbon. Rohan envisions a future where construction doesn’t come at the cost of the environment. 

On the other side of the situation is Yuki, the CFO of CityScape Builders, who is concerned about the project’s bottom line. Yuki is wary of any actions that could escalate costs and understands that using low-embodied carbon materials often comes with a higher price tag.  

In light of this situation, Avery proposes exploring different options of construction methods and materials that could be used in the design of their skyscrapers. Avery needs to do this quickly to avoid any delay, and therefore consider just the most important carbon-emitting aspects of the different options.  

 

Optional STOP for questions and activities 

 

Part two:

CityScape Builders is now embarking on a new challenge, ResilientCoast, a construction project located in a coastal area that is susceptible to climate change-related disasters. This region is economically disadvantaged and lacks the financial resources often found in more developed areas.  

Micha, the resilience project manager at CityScape Builders, is tasked with ensuring the project’s durability in the face of disasters and the impacts of climate change. Micha’s primary concern is to create a resilient structure that can withstand extreme weather events but is equally dedicated to sustainability goals. To navigate this complex situation, Micha seeks guidance from Dr. Ravi, a climate scientist with expertise in coastal resiliency. Dr. Ravi is committed to finding innovative and sustainable solutions that simultaneously address the climate change impacts and reduce embodied carbon in construction. 

In this scenario, Bao, the local community leader, also plays a crucial role. Bao advocates for jobs and economic development in the area, even though Bao is acutely aware of the inherent safety risks. Bao, too, understands that balancing these conflicting interests is a substantial challenge. 

In this situation, Micha wonders how to construct safely in a vulnerable location while maintaining sustainability goals.  

 

Optional STOP for questions and activities 

 

Part three: 

Robin and Samir are two independent sustainability consultants that are supporting the projects in ReviveRise District and ResilientCoast respectively. They are concerned that sustainability is just being assessed by embodied carbon and cost sustainability, and they believe that sustainability is a much broader concept than just those two indicators. Robin is the independent environmental consultant working with ReviveRise District officials and is responsible for assessing the broader environmental impacts of the construction project. Robin’s analysis spans beyond embodied carbon, considering local job creation, transportation effects, pollution, biodiversity, and other aspects of the project. 

Samir, on the other hand, is a municipal board member of ResilientCoast. Samir’s role involves advocating for the local community while striving to ensure that sustainability efforts do not compromise the safety and resilience of the area. Samir’s responsibilities are more comprehensive than just economic considerations; they encompass the entire well-being of the community in the face of climate change. 

Robin and Samir recognise the need for cross-city collaboration and information sharing, and they want to collaborate to ensure that the sustainability efforts of both projects do not create unintended burdens for their communities. They acknowledge that a comprehensive approach is necessary for analysing broader impacts, and to ensure both the success of the construction projects and the greater good of both communities. They believe in working collectively to find solutions that are not only sustainable but also beneficial to all stakeholders involved. 

 

Optional STOP for questions and activities 

 

The above questions and activities call for the involvement of cross-disciplinary teams, requiring expertise not only in engineering but also in planning, policy, and related fields. Ideally, in the classroom setting, students with diverse knowledge across these disciplines can be grouped together to enhance collaboration and address the tasks proposed. In cases where forming such groups is not feasible, the educator can assign specific roles such as engineer, planner, policymaker, etc., to individual students, ensuring a balanced representation of skills and perspectives.

Who is this article for? This article should be read by educators at all levels in higher education who are seeking an overall perspective on using PBL for integrating sustainability in engineering education. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise: 

Engineering graduates are increasingly required to implement sustainability-focussed initiatives within industry, alongside enhanced expectations from professional bodies and the UK specification (UK-SPEC) for engineers (Engineering Council, 2024). However, a recent study of UK Higher Education institutions highlighted that only a handful have implemented Education for Sustainable Development (ESD) into their curricula in a systemic manner ​(Fiselier et al., 2018)​, which suggests many engineering institutions still need support in this area. This article aims to explain opportunities and challenges for integrating ESD into engineering programmes via project-based learning. 

 

 1. An overview of problem-based learning as a tool for teaching sustainability within engineering:

To develop sustainability-literate graduates, the Higher Education Academy (AdvanceHE) and the UK Quality Assurance Agency for Higher Education (QAA) emphasise that students need to:  

  1. understand what the concept of environmental stewardship means for their discipline and their professional and personal lives; 
  2. think about issues of social justice, ethics, and wellbeing, and how these relate to ecological and economic factors; and 
  3. develop a future-facing outlook by learning to think about the consequences of actions, and how systems and societies can be adapted to ensure sustainable futures (QAA & HEA, 2014).  

Problem-Based Learning (PBL) provides a suitable teaching method for addressing these educational objectives. It is an influential approach in engineering education that emphasises real-world problem-solving and student-centred investigation. PBL deeply engages engineering students, prompting them to develop higher-level thinking skills while they personally confront and navigate economic, social, and environmental issues. This method fosters holistic systems thinking, interdisciplinary insights, ethical considerations, and an emphasis on the long-term viability of technical solutions (Cavadas and Linhares, 2023), while also inspiring and motivating learners (Loyens, 2015). 

While PBL can be delivered through theoretical case study examples, the term is used interchangeably with Project-Based Learning within engineering education. Both problem-based learning and project-based learning share characteristics such as collaboration and group work, the integration of knowledge and practice, and foregrounding problem analysis as the basis of the learning process (De Graaff and Kolmos, 2003). One of the main differences is where the parameters lie: with problem-based learning the parameters are defined at the beginning and students are able to find a range of solutions; with project-based learning the parameters lie at the end and students are expected to reach a specific end solution (Savery, 2006). There is also a difference in the role of the tutor and the information they provide: in problem-based learning the tutor facilitates but gives little information, while in project-based learning they are both a facilitator and a source of knowledge (Savery, 2006). Project based learning may be more accepted within engineering education since it is considered to more closely resemble the reality of the profession (Perrenet, Bouhuijs and Smits, 2000), hence Aalborg’s working definition of PBL as “Problem-Oriented, Project-Organized, Learning” (Dym et al., 2005).  

PBL thus facilitates the creation of immersive student-centric environments where group projects enable collaborative learning (Kokotsaki, Menzies and Wiggins, 2016). As Lozano et al. (2017) highlight, the nature of PBL advances critical thinking and problem-solving in engineering contexts, enabling students to critically reflect on sustainability concepts and apply this understanding to real-world challenges. Importantly, it is paramount in engineering education to foster action-oriented competencies and incorporate social contextualisation aspects (Fogg-Rogers et al., 2022), such as ethical nuances, justice, and equality, ensuring a comprehensive grasp of an engineer’s role amidst evolving societal and environmental challenges (Wang et al., 2022).  

 

2. Overcoming challenges within PBL:

While PBL presents an obvious approach for embedding sustainability, there are a series of challenges which engineering educators need to overcome to facilitate transformational learning. This section presents some of the most common challenges encountered, along with pedagogic solutions.  

 

Lack of apparent topic relevance
Sustainability topics can sometimes be treated as isolated topics, rather than an integrated aspect of an engineering problem. A perception of sustainability in engineering is that it is not implicit in design, manufacture, and operation; rather it is often perceived as an ‘add-on’ to technical skill development. This applies to both students and teachers: both require support to understand the relevance and complexities of sustainability. When academics delivering sustainability materials may struggle to relate the topic to their own engineering disciplines, students may fail to see how they can impact change. Students must work on real-world projects where they can make a difference locally or globally, and they are more inclined towards sustainability topics that are relevant to their subject discipline with subject experts.  

 

Dealing with an overwhelming amount of information
Students can be overwhelmed by the large amounts of multidisciplinary information that needs to be processed when tackling real-world problems. This can also be a challenge for academics delivering teaching, especially if the topic is not related to their speciality. Additional support (and training), along with allocation of teaching workload, are needed to successfully integrate sustainability contexts for both staff and students.   

 

Group work challenges
PBL is best conducted by mixing individual study and group work. However, groups can fail if group creation, monitoring, supporting, and assessing processes are inconsistent, or not understood by academic tutors or students. Tutors need to act as group facilitators to ensure successful collaborative learning.  

 

Issues with continual engagement
PBL often requires active engagement of students over an extended period (several weeks or months). This can be a challenge, as over time, students’ focus and priorities can change. We suggest that whole programmes need to be designed around PBL components, so that other modules and disciplines provide the scaffolding and knowledge development to the relevant PBL topics.  

 

Delivering PBL online 

PBL is best delivered using experiential hands-on learning. For example, at UWE Bristol, this is provided through civic engagement with real-world industry problems and service learning through engagement with industry, schools, and community groups ​(Fogg-Rogers et al., 2017)​. This experiential learning was exceptionally challenging to deliver online during the COVID-19 pandemic, and programmes would need to be re-designed for online learning. 

 

3. Recommendations for successful implementation of PBL:

Sustainability topics need to be embedded within engineering education so that each discipline-specific engineering problem is explored within PBL from a technical, economic, ethical, and sustainability perspective.  Drawing from UWE Bristol’s journey of ESD implementation using PBL, key recommendations are outlined below.  

 

Managing academic workload
In the initial phases of ESD integration at UWE Bristol, a small number of committed academics contributed a lot of time, effort, and dedication to push through and enable ESD acceptance from staff and students. Programme-wide implementation of ESD required wider support at the institutional level, alongside additional support for module leaders and tutors, so they felt capable of delivering ESD with a realistic workload. 

 

Structured delivery of ESD
Structuring delivery over time and throughout different modules enables students to work through large amounts of information. Providing summative feedback/assessments during key phases of the PBL exercise can also help students stay on track and manage their workload. At UWE Bristol, group presentations with pass/fail grading are introduced mid-project, so students can present information gathered about the context, before beginning problem-solving. 

 

Managing group work challenges
PBL is best conducted by mixing individual study and group work. Ensuring assessment briefs have implicit sustainability requirements is vital to embedding ESD concepts, so that students can see the need for engagement. This is further enhanced by stating the relevance to workplace contexts and UK-SPEC requirements. Tutors need to facilitate group dynamics and engagement, along with providing support structures for students who, for whatever reason, are unable to engage with group work.  

 

Creating an enabling environment for ESD integration
The integration of sustainable development throughout the curricula at UWE Bristol has been supported at the institutional level, and this has been critical for the wide scale rollout. An institution-wide Knowledge Exchange for Sustainability Education (KESE) network was created to support staff by providing a platform for knowledge sharing. Within the department, Staff Away days were used to run sustainability workshops to discuss ESD and topics of interest to students. An initial mapping exercise was conducted to highlight where sustainability was already taught within the curriculum and to identify the discipline relevant contexts (Lamere et al., 2022). Further training and industrially relevant contexts were provided to convince some staff that sustainability needed to be included in the curriculum, along with evidence that it was already of great relevance in the wider engineering workplace. This led to the development of an integrated framework of key learning requirements which embedded professional attributes and knowledge of the UK-SPEC.  

 

Student motivation and continual engagement  

For sustainability education to be effective, the content coverage should be aligned, or better still, integrated, with the topics that form part of students’ disciplinary studies. To maintain continual engagement during the PBL delivery and beyond, clear linkages need to be provided between learning and future career-related practice-based sustainability activities. Partnerships have been developed with regional stakeholders and industry, to provide more context for real-world problems and to enable local service learning and community action (Fogg-Rogers, Fowles-Sweet, 2018). Industry speakers have also been invited to contribute to lectures, touching on a wide range of sustainability and ethical issues. ESD teaching is also firmly linked to the individual’s own professional development, using the UK-SPEC competency requirements, and linked to end-point assessments. This allows students to see the potential impact on their own professionalism and career development. 

 

These recommendations can enable engineering educators to integrate sustainability topics within the curriculum using PBL to enhance student learning and engagement.

Who is this article for? This article should be read by Chemical Engineering educators in higher education who are seeking to integrate sustainability in their project modules. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise: 

The design project (DP) is considered to be the major focus of the CE curriculum, where students work in groups to design a complete chemical process – feeds, products process routes, energy requirements, financial aspects and emissions.  It is considered challenging for various reasons including the following: the requirement to recall and combine knowledge covered previously in taught classes (some of which may have been forgotten), dealing with a huge corpus of data (unavailability, uncertainty, some being in conflict and some being superfluous) and all the design decisions that need to be made from many options.  This is a major contrast with standard taught modules where all the data required is normally provided in advance.  Just making decisions is not enough – they need to be timely and justified otherwise the project may be rushed and may not complete by the deadline.  This is why the DP is valued by employers.  Furthermore, if Education for Sustainable Development (ESD) is embedded in the design project, it is more likely that students will take forward sustainability into the workplace. Figure 1 illustrates Chemical processes and the design project.   

 

1. Subject (CE) and DP pictorial representations:

Part (a) is a generic representation of a chemical process and shows the input-output nature of chemical processes.  A chemical process takes a feed and converts it to useful products (the process shown has two equipment units and four streams). Part (b) is a representation of the design project, where the specification (or brief) is provided to groups at the start (DSpec) and the final submission (or solution) is the information in part (a).  Part (c) shows that specifications can be product-based (the top two) or feed-based (the bottom two).  The dashed lines indicate specifications where the flowrate and composition of the feed/product is subject to design choice – a typical factor that will extend the design procedure and require more decision-making. 

 

 2. Inclusion of sustainability in the project topic and communication with students:

This is fairly straightforward in CE design projects, because of the circular economy and the associated waste minimisation.  So, from Figure 1, a feed-based (rather than product-based) specification can be employed.  Topics that have been used at Strathclyde in recent years have been the utilisation of coffee grounds, food waste and (in 2024) green and garden waste. It is helpful that such topics can be linked to many of the UN SDGs. Furthermore, waste products are often complex with many components, and one of the characteristics of chemical engineering is the various separation techniques. These two factors should be communicated to students to improve engagement.   

 

3. Inclusion of sustainability as an ESD activity to be carried out by groups:

One of the complicating factors about the UN SDGs is that there are so many, meaning that there is the possibility of a chemical process having both positive and negative impacts on different SDGs. This means that groups really need to consider all of the SDGs.  This might be conveniently demonstrated as per Table 1.  Certainly, it would be hoped that there are more ticks in column 2 than in column 3.  Column 4 corresponds to minimal change, and column 5 where there is not enough information to determine any impact. 

 

Table 1: Sustainability rating form for design project submissions   

As an example, consider a design project which is based on better utilisation of green waste.  Let us say that this results in less greenhouse gas emissions, as well as there being less need to plant and harvest plants.  This will result in positive outcomes for SDG12 and SDG13.  There are also positive effects because more land can be used for crops, and there will be higher plant coverage during the year.  It could be argued then that there are minor positive effects om SDG2 and SDG3.  The subsequent SDG profile in Table 1 shows two major impacts and two minor impacts – this might be typical for DPs.  

 

4. Assessment of sustainability in the design project:

Table 2 shows the typical sections in a DP submission.  For convenience these are shown as having equal 20-mark contributions.  One way of determining marks is to divide these sections into a number of dimensions, for example: use of the literature, technical knowledge, creativity/innovation and style/layout.  Sustainability could then be included as a fifth dimension.  It is then a case of determining the sustainability dimension for each of the marking sections.  It could be argued that sustainability is particularly important at the start of the project (when feeds and amounts are being decided) and at the end (when the final process is being assessed).  This explains the larger weightings in Table 2. Coherence refers to how well the submission reads in terms of order and consistency and is thus independent of sustainability.  The weightings are subject to debate, but they do at least give the potential for consistent (and traceable) grading between different assessors.

Premise:  

Education for Sustainable Development (ESD) is defined by UNESCO (2021) as:  “the process of equipping students with the knowledge and understanding, skills and attributes needed to work and live in a way that safeguards environmental, social and economic wellbeing, in the present and for future generations.” All disciplines have something to offer ESD, and all can contribute to a sustainable future. This guide presents how to embed the Sustainable Development Goals (SDGs) into undergraduate computing projects, using problem-based learning and teamwork as the main pedagogical tools (Mishra & Mishra, 2020).  

 

Embedding Sustainable Development Goals (SDGs) into computing group projects: 

Typically, the aim of the undergraduate Computing Group Project is to: 

This type of project provides students with an opportunity to integrate various skills, including design, software development, project management, and effective communication.  

 

In this project setting, the students can be asked to select a project theme based on the SDGs. The module team then can support student learning in three key ways: 

1. Lectures, labs, and regular formative assessments can build on lab activities to walk the project groups through a sustainability journey that starts from a project pitch, continues with design, implementation, and project progress reporting, and ends with delivering a final demo.

2. Blending large classroom teaching with small group teaching, where each group is assigned a tutor, to ensure timely support and feedback on formative assessments.

3. A summative assessment based on a well-structured project portfolio template, guiding students to present and reflect on their individual contribution to the group effort. This portfolio may form the only graded element of their work, giving the students the opportunity to learn from their mistakes in formative assessments and present their best work at the end of the module.  

 

Mapping the learning outcomes to the eight UNESCO key competencies for sustainability (Advance HE, 2021), the students will have the opportunity to experience the following: 

 

More specifically, sustainable development can be embedded following a lecture-lab-formative assessment-summative assessment path: 

1. Introduction lecture: Introduce the SDGs and give real-life examples of software that contribute to SDGs (examples include: for SDG 2 – Zero Hunger, the World Food Programme’s Hunger Map; SDG 13 – Climate Action, Climate Mind ). The students then can be instructed to do their own research on SDGs. 

2. Apply design thinking to project ideation: In a lecture, students are introduced to design thinking and the double-diamond of design to use a diverge-converge strategy to first “design the right thing” and second “design things right.” In a practical session, with teaching team support, the students can meet their groups for a brainstorming activity. It is essential to inform students about setting ground rules for discussion, ensuring all voices are heard. Encourage students to apply design thinking to decide which SDG-based problem they would like to work on to develop a software solution. Here, giving students an example of this process based on a selected SDG will be useful. 

3. Formative assessment – project pitch deliverable: The next step is to channel students’ output of the design thinking practical to a formative assessment. Students can mould their discussion into a project pitch for their tutors. Their presentation should explain how their project works towards one or more of the 17 SDGs. 

4. Summative assessment – a dedicated section in project portfolio: Finally, dedicating a section in a project portfolio template on ideation ensures students reflect further on the SDGs. In the portfolio, students can be asked to reflect on how individual ideas were discussed and feedback from different group members was captured. They should also reflect on how they ensured the chosen problem fits one or more SDGs, describe the selection process of the final software solution, and what alternative solutions for the chosen SDG they have discussed, elaborating on the reasons for the final choice. 

 

Conclusion: 

Computing projects provide an excellent opportunity to align teaching, learning, and assessment activities to meet key Sustainable Development competencies and learning outcomes. The projects can provide transformational experiences for students to hear alternative viewpoints, reflect on experiences, and address real-world challenges.

Premise:  

Global challenges that call for environmental, sustainable and innovative solutions have consistently pushed us to be open to the changes and challenges within engineering education (Graham, 2012; Graham, 2018; Crawley et al., 2014; Lawlor, 2013; The Royal Academy of Engineering, 2007). Despite the prevalence of the UN Sustainable Development Goals (SDGs) since 2015, several reports and studies (Mulder et al., 2012; Buckler and Creech, 2014; Lazzarini et al., 2018; Morrissey, 2013; Neubauer et al., 2017; Wals, 2014; Miñano Rubio et al. 2019) have noted that the incorporation of sustainability within universities finds the greatest barrier in the field of teaching, with curricula often failing to address key environmental and ethical issues. This situation reflects the need for educators to develop a toolkit of resource materials that can serve as a reference guide for the effective and systematic integration of sustainability into university engineering curricula (Thürer et al., 2018).  

 

Basic principles for embedding sustainability and ethics:  

The principles for integrating sustainability into mathematical problems and exercises within the engineering curricula share strong parallels to the embedding of ethical components, as documented within several guidance articles from the EPC’s Engineering Ethics Toolkit. Some of these include:  

 

 

 

 

 

Examples of mathematical problems with embedded sustainability:  

The following three example problems from Chiodo and Muller, 2023 with minor adaptations (as permitted under the Creative Commons License CC BY-SA 4.0), illustrate ways in which sustainability aspects can be integrated within traditional technical exercise questions found in engineering mathematics courses:  

Partial solution comments have been included here for brevity, please refer to Chiodo and Muller, 2023 for full solution details.  

 

Problem 1: Pipeline construction 

Topic: Optimisation. 

SDG mapping: SDG 7 (Affordable and Clean Energy), SDG 9 (Industry, Innovation and Infrastructure), SDG 14 (Life Below Water), SDG 15 (Life on Land). 

An oil company wants to build a pipeline connecting an oil platform to a refinery (on land). The coastline is straight. The oil platform is at a distance of 13km from the coast. The refinery is on the coastline, a distance 10km from the point on the coast closest to the platform. Building the pipeline will lead to a cost of £90,000 per km at sea and £60,000 per km on land.  

 

Calculate the optimal length for building the pipeline. What are the factors that need to be considered when providing a response to this question?  

 

Solution comments: The cost-minimising path is given by Snell’s law and is an exercise in trigonometry and calculus. But who said we were optimising over cost? This is an assumption often engrained into engineers while they are students, but it need not always be the right way to optimise. How many decisions made by government agencies (often based on advice offered by mathematical consultants) use economics as the sole criterion for optimisation?  

Economic actions almost always have externalities, such as possible damage to the environment (the pipe may go through a coral reef or protected habitat) or to existing infrastructure (it may go through a school or a site of archaeological significance). How could we mathematically model the environmental and human impact of laying this pipe? There are numerous factors to consider and students, much like policymakers would, should take a holistic view of these effects and at least be aware of, and question the implications of basing decisions solely on economic factors. 

 

Problem 2: Environmental disasters 

Topic: Differential equations. 

SDG mapping: SDG 6 (Clean Water and Sanitation), SDG 12 (Responsible Consumption and Production). 

A chemical accident took place near a small village in Peru. The region’s local water reservoir has a volume V. The inflow and outflow of the reservoir is given by the flow rate r. Let x(t) be the amount of mercury in the reservoir at time t. Assume that the reservoir was clean at the beginning i.e., x(0) = 0. Let C(t) be the concentration of mercury flowing into the reservoir.  

 

a. Set up and solve a differential equation describing the concentration of the reservoir.  

b. How can you use your solution to model repeated pollution (e.g., criminals dumping mercury near the reservoir every weekend)?  

c. What are some relevant questions you can ask about the concentration of mercury in the reservoir?  

d. Suppose that the polluter is caught and after some cleaning, the incoming water is clean. How can you use your model to analyse when the water in the reservoir will be safe again? How sure are you of your answer and how much does it matter?  

 

Solution comments: This question is designed to show students that very simple mathematics can be used to model local environmental disasters, which can often be an example of how it may be used unsustainably. It teaches students to find good questions instead of merely answering someone else’s questions. 

For part c), possible questions for students to consider can include:  

For part d) for the sub question “How sure are you?”, students will need to explore what the ‘known’ unknowns are e.g., errors in the measurement apparatus, non-uniform mixing, samples taken in a very clean/dirty part of the stream or reservoir. They may also need to consider any ‘unknown’ unknowns e.g., other sources of pollutants, samples being tampered with accidentally or deliberately, etc. 

For part d) for the sub question “How much does it matter?”, students should identify that we are dealing with poison in drinking water, so it matters immensely! They should understand that this is an estimate, which helps forecast when the water might be safe to drink (the only way to actually know is to thoroughly test it). This question helps students to realise that the mathematics is simply one part of a much bigger solution and should not be relied upon as a definitive answer to a question as serious as the safety of drinking water.  

 

Problem 3: Simpson’s paradox 

Topic: Probability. 

SDG Mapping: SDG 5 (Gender Equality), SDG 10 (Reduced Inequalities). 

In a particular admissions cycle, a mathematics department observes a higher success rate for male applicants than for female applicants. To investigate whether this is the same across he two sub-departments of Pure Mathematics and Applied Mathematics, the following year the department asks each applicant to give their preference for pure or applied mathematics (they are not allowed to be ambivalent) and records the resulting statistics as shown in Figure 4 below:  

                                                                            Total

Applications Successful
Female 300 30
Male 1000 210
              Prefer applied

Applications Successful
Female 270 18
Male 350 15
                     Prefer pure

Applications Successful
Female 30 12
Male 650 195

 

 

          Figure 4: Admission statistics for male and female applications to study mathematics  

 

 

a. Compare the success rates for male and female applicants that prefer applied mathematics, prefer pure mathematics and their success rates overall.  

b. What do you notice? Why is this possible? This is known as Simpson’s Paradox.  

c. If possible, find the admission statistics by gender and mathematics preference (pure/applied) from your university’s mathematics department and see if the same phenomenon occurs.  

 

Solution comments: The purpose of this question is to demonstrate Simpson’s paradox in which a trend appears in several different groups of data but disappears or reverses when these groups are combined. It also attempts to highlight the immense gender disparity in many mathematics departments around the world.  

For part b) it is evident from the calculations in part a) that females with a given preference (pure/applied mathematics) have a higher success rate than males with the same preference, but lower overall. This is Simpson’s Paradox. The heuristic reason for why this is possible is that the largest male cohort (those that prefer pure) has a much higher acceptance rate than the largest female cohort (those that prefer applied). So, the overall acceptance of men is dominated by those who prefer pure, while the overall acceptance of women is dominated by those who prefer applied. This is a great lesson in why it is usually a terrible idea to take “averages of averages”. 

The main purpose of part c) is not so much for students to redo the calculation (it is not a given that Simpson’s Paradox will always arise here), but rather to illustrate the immense gender disparity in many mathematics departments around the world.  

  

Conclusion:  

The aim of this article is to provide academics and educators in higher education with an insight into how sustainability concepts may be integrated into technical, mathematical problems prevalent throughout engineering curricula. This should hopefully motivate lecturers to design their own versions of similar exercises to embed within their own courses and help build on ongoing calls to enhance the restructuring of our university programmes to better prepare future engineers to tackle global sustainability challenges by drawing not only on their technical and scientific knowledge, but also on their creativity, ethical, professional and leadership skills.

Who is this article for? This article should be read by educators at all levels in higher education who are curious about how maker spaces and communities can contribute to sustainability efforts in engineering education. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise:  

Makerspaces can play a valuable role in Education for Sustainable Development (ESD). In this article, we highlight three specific contributions they can make to ESD in Engineering: Makerspaces enable engineering in real-world contexts; they build cross-disciplinary connections and inclusive learning; and they promote responsible consumption.   

 

A brief introduction to makerspaces: 

In recent years, a ‘makerspace’ movement has emerged in Higher Education institutions. While most prevalent in the US, there are now a number of university-based makerspaces in the UK, including the iForge at the University of Sheffield, the Institute of Making at UCL, and the Makerspace at King’s College London. So what is a makerspace, and what do they have to do with Education for Sustainable Development (ESD)?  

Makerspaces are part of a larger “maker movement” that includes maker fairs, clubs and magazines. Within universities, they are “facilities and cultures that afford unstructured student-centric environments for design, invention, and prototyping.” (Forest et al., 2016). Successful and inclusive makerspaces are student led. Student ownership of makerspace initiatives deepens student motivation, promotes learning, and encourages peer-to-peer collaboration. Successful makerspaces produce thriving learning communities, through which projects can emerge organically, outside of curriculum structures and discipline boundaries.  

In terms of Education for Sustainable Development (ESD), this means that students can bring their passion to make a difference, and can meet other students with similar interests but complementary skill sets. With support from the University, they can then be given opportunities to put their passion and skills into practice. Below, we focus on three concrete contributions that makerspaces can make to ESD:  Opportunities for applied learning; expanded potential for cross-disciplinary learning, and the chance to deepen engaged learning on sustainable consumption.  

 

1. Maker communities enable engineering in real world contexts:

1.1 ESD rationale 

ESD enables students to think critically about possible solutions to global challenges. It encourages students to consider the social, economic, and political context in which change takes place. ESD also spurs students to engage, where possible, with those beyond the university.  

It may be tempting to think of engineering as simply a technical exercise: one in which scientific and mathematical knowledge is taken and applied to the world around us. In practice, like all other professions, engineers do not simply apply knowledge, they create it. In order to do their work, engineers build, hold, and share ideas about how the world works: how users will behave; how materials will function; how they can be repaired or disposed of; what risks are acceptable, and why. These ideas about what is reasonable, rational, and probable are, in turn, shaped by the broader social, political, and economic context in which they work. This context shapes everything from what data is available, to what projects are prioritised, and how risk assessments are made. Rather than trying to ignore or remove these subjective and context-based elements of engineering, we need to understand them. In other words, rather than ask whether an engineering process is impacted by social, political, and economic factors we need to ask how this impact happens and the consequences that it holds. ESD encourages students to think about these issues.  

 

1.2 The contribution of makerspaces 

The availability of both equipment and expertise, and the potential for practical solutions, means that makerspaces often attract projects from outside the university. These provide opportunities to practise engineering in real-world contexts, where there is the possibility for participatory design. All such projects will require some consideration of social, political, or economic factors, which are at the heart of the Sustainable Development Goals.  

One example of this is SheffHEPP, a hydroelectric power project at the University of Sheffield. In response to requests for help from local communities, students are designing and building small-scale hydroelectric power installations in a number of locations. This multidisciplinary project requires an understanding of water engineering, electrical power generation, battery storage and mechanical power transmission, as well as taking into consideration the legal, financial, and environmental constraints of such an undertaking. But it also requires Making – students have made scale models and tested them in the lab, and are now looking to implement their designs in situ. Such combinations of practical engineering and real-world problems that require consideration of the wider context provide powerful educational experiences that expose students to the realities of sustainable development. 

 

There are a number of national and international organisations for students that promote SDGs through competitions and design challenges. These include: 

 

Student engagement with such activities is growing exponentially, and makerspaces can benefit students who are prototyping ideas for the competitions. At Sheffield, there are over 20 co-curricular student-led projects in engineering, involving around 700 students, many of which engage with the SDGs. In addition to SheffHEPP and teams entering all of the above competitions, these include teams designing solutions for rainwater harvesting, vaccine storage, cyclone-proof shelters for refugees, plastics recycling, and retrofitting buildings to reduce energy consumption. As well as the employability benefits of such activities, students are looking for ways to use engineering to create a better future, with awareness of issues around climate change and sustainability increasing year on year. And none of these activities would be possible without access to maker facilities to build prototypes.  

 

Linked to the makerspace movement is the concept of hackathons – short sprints where teams of students compete to design and prototype the best solution to a challenge. At Sheffield, these have included: 

 

In summary, Makerspaces enable students to access multiple initiatives through which they can engage in learning that is potentially participatory and applied. These forms of learning are critical to ESD and have the potential to address multiple Sustainable Development Goals.  

 

2. Maker communities build cross-disciplinary connections and encourage inclusive learning:

2.1 ESD rationale 

Global complex challenges cannot be resolved by engineers alone. ESD encourages students to value different forms of knowledge, from within and beyond academia. Within academia, makerspaces can provide opportunities for students to collaborate with peers from other disciplines. Cross-disciplinary knowledge can play a crucial role in understanding the complex challenges that face our world today. Makerspaces also offer an opportunity for students to engage with other forms of knowledge – such as the knowledge that is formed through lived experience – and appreciate the role that this plays in effective practices of design and creation. Finally, makerspaces can help students to communicate their knowledge in ways that are understandable to non-specialist audiences. This inclusive approach to knowledge creation and knowledge sharing enables students to think innovatively about sustainable solutions for the future.  

 

2.2 The contribution of makerspaces   

Cross-disciplinary spaces  

Student-led makerspaces encourage students to lead in the creation of cross-disciplinary connections. For example, at the University of Sheffield, the makerspace has primarily been used by engineering students. Currently, however, the students are working hard to create events that will actively draw in students from across the university. This provides students with a co-created space for cross-disciplinary exchange as students train each other on different machines, learning alongside each other in the space. At other times, staff from different disciplines can come together to create shared opportunities for learning. 

The cross-disciplinary nature of makerspaces and the universality of the desire to create encourages a diverse community to develop, with inclusivity as a core tenet. They can often provide opportunities for marginalised communities. Makerspaces such as the ‘Made in Za’atari’ space in Za’atari refugee camp have been used to give women in the camp a space in which they can utilise, share, and develop their skills both to improve wellbeing and create livelihoods. Meanwhile, projects such as Ambessa Play have provided opportunities for young people in refugee camps across the world to learn about kinetic energy and electronic components by creating a wind-up flashlight.  

 

Spaces of inclusive learning  

Maker projects also allow students to engage with their local communities, whether creating renewable energy installations, restoring community assets or educating the next generation of makers. Such projects raise the profile of sustainable development in the wider public and give students the opportunity to contribute to sustainable development in their neighbourhoods. 

 

3. Maker communities promote responsible consumption:

3.1 ESD rationale 

ESD does not just influence what we teach and how we teach; it also shapes who we are. A central tenet of ESD is that it helps to shape students, staff, and educational communities. When this happens, they are – in turn – better able to play their part in shaping the world around them.  

 

3.2 The contribution of makerspaces  

Even before the concept was popularised by the BBC’s ‘The Repair Shop’, repair cafes had begun to spring up across the country. Such facilities promote an ethos of repair and recycling by sharing of expertise amongst a community, a concept which aligns very closely with the maker movement. Items repaired might include furniture, electrical appliances, and ornaments. Related organisations like iFixit have also helped to promote responsible consumption and production through advocacy against built-in obsolescence and for the ‘Right to Repair’. 

The same principles apply to Making in textiles – sustainable fashion is a topic that excites many students both within and outside engineering, and makerspaces offer the opportunity for upcycling, garment repair and clothes shares. Students can learn simple techniques that will allow them to make better use of their existing wardrobes or of used clothing and in the process begin to change the consumption culture around them. At the University of Sheffield, our making community is currently planning an upcycled runway day, in which students will bring clothing that is in need of refresh or repair from their own wardrobes or from local charity shops. Our team of peer-instructors and sewing specialists will be on hand to help students to customise, fit, and mend their clothes. In doing so, we hope to build an awareness of sustainable fashion amongst our students, enabling an upcycling fashion culture at the university.  

 

Conclusion: 

Education for Sustainable Development plays a vital role in enabling students to expand the knowledge and skills that they hold so that they can play their part in creating a sustainable future. Makerspaces offer a valuable route through which engineering students can engage with Education for Sustainable Development, including opportunities for applied learning, cross disciplinary connections, and responsible consumption.

Who is this article for? This article should be read by educators at all levels in higher education who wish to consider how to navigate tradeoffs between economic and environmental sustainability as they apply to engineering. Engaging with this topic will also help to prepare students with the soft skill sets that employers are looking for. 

 

Premise:  

In the face of the ever-growing need for economic progress and the escalating environmental crises, the engineering profession finds itself at a crossroads. Striking a delicate balance between economic growth and environmental sustainability is no longer an option but an imperative. This article delves into the pivotal role of engineering educators in shaping the mindset of future engineers, offering an expanded educational framework that fosters a generation capable of harmonising economic prosperity with environmental responsibility. 

  

The uneasy truce:  

Developing nations, with burgeoning populations and aspirations for improved living standards, grapple with the paradox of rapid economic expansion at the expense of environmental degradation. This necessitates a shift in focus for engineering educators, who bear the responsibility of cultivating engineers with a foresighted perspective. Rather than demonising economic growth, the goal is to instill a nuanced understanding of its interdependence with environmental well-being. For example, in developing countries like Brazil, rapid economic expansion driven by industries such as agriculture and logging has resulted in extensive deforestation of the Amazon region. This deforestation not only leads to the loss of valuable biodiversity and ecosystem services but also contributes to climate change through the release of carbon dioxide. Similarly, in industrialised nations, the pursuit of economic growth has often led to the pollution of air, water, and soil, causing adverse health effects for both humans and wildlife. 

 

Equipping our future stewards: 

To navigate this delicate landscape, educators must move beyond traditional technical expertise, fostering a holistic approach that integrates ethical awareness, interdisciplinary collaboration, localised solutions, and a commitment to lifelong learning. 

1. Ethical awareness: One potential counterargument to the expanded educational framework may be that the focus of engineering education should remain solely on technical expertise, with the assumption that ethical considerations and interdisciplinary collaboration can be addressed later in a professional context. However, research has shown that integrating ethical awareness and interdisciplinary collaboration early in engineering education not only enhances problem-solving skills but also cultivates a sense of responsibility and long-term thinking among future engineers. 

2. Holistic thinking: Research has shown that interdisciplinary collaboration between engineering and social science disciplines can lead to more effective and sustainable solutions. For instance, a study conducted by the World Bank’s Water and Sanitation Program (WSP) found that by involving sociologists and anthropologists in the design and implementation of water infrastructure projects in rural communities, engineers were able to address cultural preferences and local knowledge, resulting in higher acceptance and long-term maintenance of the infrastructure. Similarly, a case study of a renewable energy project in Germany demonstrated how taking into account the geographic nuances of the region, such as wind patterns and solar radiation, led to more efficient and cost-effective energy solutions. Presently, Germany boasts the world’s fourth-largest installed solar capacity and ranks amongst the top wind energy producers.  

3. Localised solutions: Students must be required to consider the social, cultural, and geographic nuances of each project. This means moving away from one-size-fits-all approaches and towards an emphasis on the importance of context-specific solutions. This ensures that interventions are not only technologically sound but also culturally appropriate and responsive to local needs, fostering sustainability at both the project and community levels. 

4. Lifelong learning: Empower students with the skills to stay abreast of emerging technologies, ethical frameworks, and policy landscapes. Recognise that the landscape of sustainability is dynamic and ever evolving. Foster a culture of continuous learning and adaptability to ensure that graduates remain true stewards of a sustainable future, equipped to navigate evolving challenges throughout their careers. 

 

A compass for progress:  

By integrating these principles into engineering curricula, educators can provide students with a moral and intellectual compass—an ethical framework guiding decisions toward a future where economic progress and environmental responsibility coexist harmoniously. Achieving this paradigm shift will require collaboration, innovation, and a willingness to challenge the status quo. However, the rewards are immeasurable: a generation of engineers empowered to build a world where prosperity thrives alongside a healthy planet—a testament to the true potential of the engineering profession. 

Engineering teachers can raise a generation of engineers who can balance economic growth with environmental responsibility by embracing a broader educational framework that includes ethical awareness, cross-disciplinary collaboration, localised solutions, and a commitment to lifelong learning. Through the adoption of these principles, engineering curricula can provide students with a moral and intellectual compass, guiding them toward a future where economic progress and environmental sustainability coexist harmoniously.

Premise: 

Engineering has always responded to the societal challenges of humanity, contributing to its progress and economic development. However, the synergetic effects of fossil-based economic growth together with large-scale engineering projects have also caused great pressures on natural resources and ecosystems leading to over-exploitation and degradation. In consequence, in the last decades, a multidimensional perspective on sustainability perspective has arisen, and has been acknowledged by social movements, governments and institutions.   

Meanwhile, this assumes deep epistemological changes, requiring holistic and transdisciplinary approaches that must be considered by engineering professionals, establishing communication based on new ways of thinking. There is the need to interweave disciplines, to establish complementary relationships, to create associations in order to root new knowledge, enabling communication between the sciences. In doing so, transdisciplinary science has emerged, i.e. the science that can develop from these communications. It corresponds to a higher stage succeeding the stage of interdisciplinary relationships, which would not only cover interactions or reciprocities between specialised research projects, but would place these relationships within a total system without any firm boundaries between disciplines (Piaget, 1972).  

Currently, the complexity associated with climate change and the uncertainty of the link between global loss of biodiversity and current loss of public health, are demanding innovative knowledge, needing those holistic and transdisciplinary approaches.  Engineering professionals must therefore give additional attention to ecological sustainability. 

 

The challenges of sustainability: 

The term “sustainability” portrays the quality of maintenance of something which can continue for an indefinite time, such as biological species and ecosystems. Sustainability is based on a dynamic balance between natural and human ecosystems, in order to maintain the diversity, complexity and functions of the ecological systems that support life, while contributing to prosperous and harmonious human development (Costanza, 1997). This strong perspective of sustainability needs to have a prominent place in land use management which must consider the carrying capacity of natural ecosystems.  

Ecological sustainability in particular aims to maintain the earth’s natural potential and the biosphere, its stock of natural resources, atmosphere and hydrosphere, ecosystems and species. Ecosystems should be kept healthy by preserving their “ecological integrity”, i.e. the capacity to maintain the structure and function of its natural communities, which includes biogeochemical cycles.  

Engineering professionals must therefore understand the global limits for water, land, and energy use (contributing to less atmospheric carbon emissions), and preserve other natural resources, such as nutrients or biodiversity. In the technical decision-making process, they need to understand the ecological impacts of big scale projects, such as transportation infrastructures, dams, deforestation, and others. Alongside other professionals, they need to contribute to the restoration, conservation and preservation of ecosystem services, e. g. support services, production services, regulating services and cultural services. These services result in benefits that people and organisations receive from ecosystems and constitute determinants of well-being (Millennium Ecosystem Assessment, 2005).  

Until now, technical solutions often focused on highly visible man-made structures, many of which stopped or disrupted natural processes. Presently, the importance of regulating natural ecosystem services such as water purification, water supply, erosion and flood control, carbon storage and climate regulation is beginning to be perceived. These are considered as soft engineering tools and must be highlighted by engineering educators and assumed in the practice. 

This ecological mindset would enable solutions that recognise management and restoration of natural ecosystems in order to curb climate change, protect biodiversity, sustain livelihoods and manage rainstorms. Nature-based solutions are a natural climate solution in cities, contributing to the mitigation and adaptation of climate change through green roofs, rain gardens, constructed wetlands that can minimise damaging runoff by absorbing stormwater, reducing flood risks and safeguarding freshwater ecosystems. They are essential in climate refuges for city residents during heatwaves and other extreme climate events. These solutions need specific and new knowledge made by ecologists working with engineers and others, which demands action beyond disciplinary silo, i.e., a transdisciplinary approach.  

Within this context, engineering professionals must consider specific operating principles of sustainability: 

These principles must be considered in engineering education, and require deep changes in teaching, because there is a great difficulty in studying and managing the socio-ecological system according to the Cartesian paradigm which breaks up and separates the parts of a whole. New ecological thinking emphasises holistic approaches, non-linearity, and values focused on preservation, conservation and collaboration (Capra, 1996). The transdisciplinary approach needs dialogic and recursive thinking, which articulates from the whole to the parts and from the parts to the whole, and can only be unchained with the connection of the different fields of knowledge, including knowledge from local communities in specific territories.   

In higher education, engineering students should establish face-to-face contacts with ecology students in order to better understand ecological sustainability and generate empathy on the subject. Engineering students must develop skills of collaboration and inter-cultural communication tools (Caeiro-Rodríguez et al., 2021) that will facilitate face to face workshops with other professionals and enrich learning experiences.  

In the 21st century, beyond the use of technical knowledge to solve problems, engineering professionals need communicational abilities to consider ecological sustainability, requiring networking, cooperating in teams, and working with local communities. Engineering educators must include trans-sectoral and transdisciplinary research and holistic approaches which make clear progress in tackling ecological sustainability. 

 

Conclusion: 

The interconnected socio-ecological system must be managed for sustainability by multiple stakeholders.  Engineering professionals need to develop a set of skills and competencies related with the ability to work with other ones (e.g. from the natural sciences) and citizens. Currently, beyond the use of technical knowledge to solve problems, engineers need to consider the sustainable development goals, requiring networking, cooperating in teams, and working with communities through transdisciplinary approaches.  

Education for Sustainable Development is required to empower engineering professionals to adopt strong sustainable actions that simultaneously ensure ecological integrity, economic viability and a just society for the current and future generations. Education is a fundamental tool for achieving the Sustainable Development Goals, as recognised in the 2030 Education Agenda, coordinated by UNESCO (2020).
