Paper Two: Environmental issues Flashcards
How was sustainable development introduced
- in 1987, the World Commission on Environment and Developmen introduced this concept
- it was defined as ‘development which meets the needs of current generations without compromising the ability of future generations to meet their own needs’
What three strands of sustainable development must be considered when designing and manufacturing
- economic
- social
- environmental
ways the designer/manufacturer can reduce environmental impact of a product: REDUCE
- cut down amount of material & energy
- eg water bottle- uses as little material as possible while still maintaining strength
ways the designer/manufacturer can reduce environmental impact of a product: REUSE
- reuse products for the same/different use at the end of life
- eg glass coffee jars can be used again with refill packs
ways the designer/manufacturer can reduce environmental impact of a product: RECYCLE
- convert waste products into new materials
PRIMARY: using functioning secondhand products (eg charity shops etc)
SECONDARY: materials recycled into different products (eg boat sails > bean bags/sailing jackets)
TERTIARY: completely breaking down product and reformulating it using chemical process (eg water bottle > fleece)
ways the designer/manufacturer can reduce environmental impact of a product: REPAIR
- fix a product when it breaks rather than discarding (eg repairing a puncture)
ways the designer/manufacturer can reduce environmental impact of a product: REFUSE
- consumer choice of whether or not to buy a product or not
- eg considering whether it has been made sustainably & ethically or not, refusing less efficient white goods- fridge, dishwasher, etc
ways the designer/manufacturer can reduce environmental impact of a product: RETHINK
- rethink the way products are designed & manufactured to be more efficient
- eg using SMAs to aid disassembly
primary carbon footprint (definition)
measures direct CO2 emissions from burning fossil fuels. Includes transport & domestic energy
secondary carbon footprint (definition)
measures indirect CO2 from products used
Economic sustainable development
- materials choice-such as the cost, use of finite resources and obtaining the original source
- processing implications-energy cost, costs associated with dealing with potential pollution
- manufacturing-cost of ensuring good working conditions for those involved in the manufacturing process
Social sustainable development
- processing implications-pollution and the impact on people’s health
- manufacturing-working conditions for those involved in the manufacturing process
Environmental sustainable development
- material choice-use of finitre resources and end of product life recycling
- processing implications-energy use and initial source and pollution
Designers and manufacturers need to consider factors that use the optimum amount of packaging to protect/preserve products and prevent waste. What are some examples of these factors
- making the packaging lightweight
- using recycled content
- making the packaging recyclable or reusable
- the use of refills and concentrates
- using minimal packaging material
- charging for items-supermarket bags
Example of product that has been designed to reduce the environmental impact
- KeepCup- a reusable coffee cup
- designed to reduced environmental impact caused by disposable cups
- 20 disposable cups and lids=enough polymer for one KeepCup
