L6 Engineering Design for Environment
What is Engineering Design?
• Is the process of developing a component, product or process to meet desired need.
• Involved engineering decisions – to make stated functional objectives with an agreed allocation of resources (budget)
What is ED for the environment?
• Involves eng. Decision making to meet objectives with an eco-efficient allocation of resources that comply with the
principle of social, economic and ecological sustainability (TBL)
• Also called eco-design, sustainable design, environmentally sustainable design, environmentally conscious design.
What makes for a good engineering design?
• Highly functional
• Efficient – using material efficiently, energy, water
• Cost effective
• Design features, more functional, stylish
• Safety features
• Longevity – well built for the environment
What makes for good engineering design for the environment?
• Recyclable, non-toxic and energy efficient
What is the engineering design process?
• Define the problem
• Do background research
• Specify requirements
• Brainstorm solutions
• Choose the best solution
• Do development work
• Build a prototype
• Test and redesign
Where does engineering design for the environment come in? – specify requirements
Design for the environment – reducing the environment impact of a product throughout its entire life (from manufacturing,
packaging, distribution, installation use and end of life)
What roles do engineers play? Why is engineering design for the environment important?
• Because we are part of the issue and we are required for the solution
• To understand the life cycle implications of our design making
• The decisions made leaves an impact on the environment
How can engineers tackle the challenges?
• Elevate our perspective and understanding
• Life cycle perspective and everything has a positive and negative impact
• Using a systematic view
• Acknowledge the problems are multi-disciplinary and will require inter-disciplinary solutions
The product of life cycle
1. Sourcing -obtaining raw materials
2. Manufacture – transforming the raw materials into the product and packaging
3. Distribution – moving the products from the production facility to retailers for sale
4. Use - the resources consumed when using the product over its lifetime
5. Recovery – waste – collecting, sorting, recycling and disposal
6. Transport – the waste – moving goods back and forth, used throughout the life cycle
SOURCING
What kind of improvements can be made?
• Alternative chemical processes that consume less energy and resources
• Minimize waste that generate through the extraction process
• Reduce the energy required to process the materials
• Replace inputs with environmentally friendly materials
• Reduce the number of inputs required for the final product
MANUFACTURE
What kind of improvements can be made?
• Reduce amount of packaging
• Improve efficiency of manufacturing process
