Sustainability Flashcards
6Rs
Repair Reduce Rethink Recycle Refuse Reuse
Repair
When a product breaks don’t or not work, fix product instead of throwing it
or have it so parts can be replaced instead of whole to repair
E.g tires and cars, replace tires instead of whole car
Refuses
Refuse to use material that impact environment or is not sustainable/ recyclable
Refuse to buy product that isn’t
Rethink
Rethink design (disassembly, longevity, dematerialisation) rethink if product is needed, rethink properties (how to make to recycle or last longer), rethink materials used
Recycle
Use recyclable or recycled materials
Recycle product after use
Obey recycle laws
Reuse
Reuse product Reusable product EG reuseable cloth masks Reusable lunch box Reusable water bottle
Reduce
Reduce energy used
Reduce material used
Product life cycle
From the collection of raw materials, transport, manufacturing, use, to the recycling or disposal at the end of the product’s life
Life cycle assessment define
A process of scientific investigation that explores the whole of life environmental impacts of a product
Why are life cycle assessments conducted/important
To get a better understanding of the products hidden environmental impacts
Customer often expect products to be daughter abd manufactured in a way that does little or no damage to the environment throughout their entire lifetime
Life cycle stages (6 marks)
Raw material extraction Transport Manufacture Transport and packaging Use Recycling or disposal
Life cycle inputs and outputs
Input: materials, output: waste
Input: energy, output: carbon emissions
Eco design strategies
Design for disassembly (designing a product so it can pulled apart easily)
Design for longevity (lasts longer)
Design for dematerialisation (using less materials without losing quality)
Decrease environmental impacts
Manufacture from sustainable, recyclable materials
Produce as little pollution as possible
Use as little energy/ fuel as possible
What is design for longevity
Design so product lasts longer
