Industrial Ecology and Sustainable Engineering (ES99L-15)

Summary

Contemporary global economic challenges, which are exacerbated by intensive competition through international trade and the rapid growth in population has led to negative impact on environmental systems (such as the diminishing finite natural resources and environmental impacts) as well as on socioeconomic systems. Addressing these challenges, without destabilising industrial and business processes whilst operating within the safe operating zone of the planetary boundaries has, therefore, become a matter of global concern and urgency. The associated complexities of these challenges including technology development, economic growth, environmental management, and social change have led to a surge in demand for the requisite knowledge and skills in the area of Industrial Ecology and Sustainable Engineering.

Industrial Ecology is an emergent interdisciplinary scientific discipline of developing nearly closed-loop industrial ecosystems of material exchange and efficient energy cascading by mimicking natural systems. Sustainable Engineering, on the other hand, supports the development of products and processes through the lens of the triple bottom line (TBL) framework, based on a balanced view of economic, environmental and social aspects. As such, sustainable engineering could be considered the operational aspects of industrial ecology in that it adopts industrial ecology tools such as lifecycle, input-output, techno-economic and material flow analyses across a range of environmental, economic, and social sustainability indices. It then adopts sustainable engineering methods to integrate that knowledge into products, processes, and services design and management. These analyses form the basis of industrial ecology and sustainable engineering that seeks to develop and manage products, processes and services that satisfies human needs in a sustainable manner.

This module is designed for students from diverse disciplinary backgrounds and aims to provide them with critical knowledge and skills to analyse and contribute to sustainable technical solutions in industry, consultancy, governmental agencies, and research. The module covers aspects including but not limited to key concepts of industrial ecology (industrial ecosystems, industrial symbiosis, and industrial metabolism), industrial ecology tools (lifecycle, input-output, techno-economic, and material flow analyses), sustainable engineering and design for environment, environmental impact assessment, sustainable production and consumption, resource/material efficiency and circular economy strategies (e.g. reuse, repair, remanufacturing and recycling), pairing disruptive digital technologies with the circular economy, sustainability in the supply chain, multi-criteria decision analysis, energy and transportation (e.g. battery systems and electric vehicles) amongst others.

Module aims

The module aims to provide students with a rich understanding of how industrial ecology and sustainable engineering serve as a framework for the consideration of environmental and sustainability-related aspects of products and processes. Drawing from multiple disciplines, including engineering, management and sustainability sciences, students will garner knowledge on underlying principles and visions as well as theory and tools that support the establishment and assessment of resource-efficient and circular measures. By exploring real-world examples, students will be able to synthesize and apply the knowledge acquired. In doing so, students would have gained broad awareness and profound understanding of the environmental, economic, social and ethical challenges as well as opportunities facing humankind.

A further module aim is that students will gain knowledge and skills about some of the analytical tools and methods applied in industrial ecology and sustainable engineering to support them to assess critical aspects of sustainability, focus on environmental impacts and resource constraints, and to suggest measures towards sustainable development.

Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

The module will be delivered across five days sessions and covers aspects including but not limited to key concepts of industrial ecology (industrial ecosystems, industrial symbiosis and industrial metabolism); industrial ecology tools (lifecycle, input-output, techno-economic and materials flows analyses; environmental impact assessment); resource/material efficiency and circular economy strategies (e.g. reuse, repair, remanufacturing and recycling); pairing disruptive digital technologies with circular economy; sustainability in the supply chain; energy and transportation (e.g. battery systems and electric vehicles) amongst others. Indicative delivery plan across the five days are detailed below:


Day 1:
Welcome and introduction to the module. Climate change and the need for mitigation strategies; industrial and natural ecosystem metaphor; ecosystems classifications; introduction, definition, goals, analytical components of industrial ecology framework (industrial ecosystems, industrial symbiosis and industrial metabolism); social dimension of industrial ecology; Eco Industrial Parks; IPAT equation (population and carrying capacity, consumption patterns and technology). Guest lecturers are invited.


Day 2:
Perspectives on the concept of sustainable development and humankind’s interaction with nature; definition and drivers of sustainability; sustainability indicators; resource sustainability challenges and opportunities (materials, energy, water); roots, rationales and core elements of resource-efficiency and the circular economy including strategies such as reuse, repair, remanufacturing and recycling; pairing disruptive digital technologies with circular economy. Real-world examples of resource-efficient and circular solutions will be explored through various lenses, aiming for gradual synthesis and applications.


Day 3:
Introduction to industrial ecology and sustainable engineering tools including lifecycle, input-output, techno-economic and material flow analyses to model product’s environmental impacts and resource constraints; case studies application of lifecycle assessment; Hands-on practical application of the tools using spreadsheet to create simple models. Overview of environmental impact assessment (EIA) and Strategic Environmental Assessments (SEA).


Day 4:
Hands-on practical application of the tools using spreadsheet to create simple models continued.


Day 5:
Energy and transportation. This will focus on battery systems and electric vehicles covering the rationale, supply chain complexities, challenges, environmental impact, recycling, opportunities and outlook. Battery electric vehicles vs. internal combustion engine vehicles. Societal attitudes to electric vehicles; recharging infrastructure. Review of the module content and discussion on the individual report.

Learning outcomes

By the end of the module, students should be able to:

  • Comprehend and synthesise the concepts of industrial ecology & sustainable engineering as frameworks for the consideration of the triple bottom line based on a balanced view of economic, environmental and social aspects of science, technology, and policy
  • Apply industrial ecology & sustainable engineering tools and techniques including lifecycle, input-output, techno-economic and material flow analyses across a range of environmental, economic, and social sustainability indices
  • Demonstrate that industrial ecology & sustainable engineering provide a solution-oriented approach to environmental and sustainability problems and understand the relationships among production, consumption, sustainability, and industrial ecology
  • Understand how the private sector, government, and NGOs can consider the values and trade-offs associated with various sustainability goals, with other quantitative analyses when approaching business, investing and policy decisions
  • Communicate orally and in writing the knowledge and skills acquired
