2.8 Responsible Design Flashcards
What’s sustainable development?
Introduced by brundtland commission
- development that meets the needs of today without hindering the needs of future generations
What are the three strands of sustainable development?
Economic
Social
Environment
What are the 6 R’s?
Recycle
Reduce
Reuse
Refuse
Rethink
Repair
What does recycling achieve?
Maintaining resources
Reducing landfill
What issues prevent recycling?
Separation difficulty- materials not in pure state
What are the recycling numbers for Polymers?
1-7
7th is others, unrecyable
What does reducing achieve?
Using less
- finite resources
- producing waste
What’s an example of encouragement to Reduce?
Carrier bag charge
Caused a 71% drop in use
What’s meant by refusing?
Not using/ doing things harmful to the environment
What’s an example of refusing?
Buying a bottle instead of using single plastics
Electrics cars rather than diesel
What’s the issue preventing repair?
Companies make products so they can’t be dismantled
- using complex screws
Why do companies prevent repair?
Want you to rebuild
Costs more to be easily dismantled
Example company which encourage repair?
Fair phones
- easily repairable and changeable
- can buy new parts eg. New camera for £25, you can replace yourself
Why are more companies making products repairable?
There’s pressure in creating a right to repair law
What’s meant by rethink?
Finding alternatives
What are some examples of rethinking?
- bicycle scheme rather than your car (Boris bikes, lime)
- putting off upgrading your phone
Examples of reusing?
Buying off or selling off vinted
Buying a bottle, refilling
What’s primary carbon footprint?
Direct emissions
Making and production
- burning
- transport
- manufacture
What’s secondary carbon footprint?
Indirect CO2 emissions
During and after use
- product use
- disposal
What are the two carbon footprint third party ratings?
Carbon Trust
Ecovadis
What’s the difference between carbon Trust and ecovadis?
Carbon trust- products
Ecovadis- companies
(va for vast, broader)
What does carbon trust do?
Assess products from their carbon footprint
Promote if sustainable
What does Ecovadis do?
Assess companies sustainability, by visiting factories (like ofsted)
Provide ratings
What’s an carbon footprint case study?
A phone
Describe what stage of a phone produce carbon footprint?
- materials
- manufacture
- delivery
- usage
- disposal
Describe materials in terms of a phone:
Metal, created from mined ores
Glass
Describe manufacture in terms of a phone:
Packaging
Describe delivery in terms of a phone:
Trucks, travel
Petrol, oil
Describe usage in terms of a phone:
Charging
Describe disposal in terms of a phone:
- dissambly
- sorting
what is a circular economy?
sustainable practice - reuse of biological and technical nutrients, rather then throwing it away
companies:
- take > make > reuse > repeat
example of closed loop:
Dyson
offer to take back old items when you buy a new one
what’s meant by product miles?
the total distance of a product
raw materials > disposal / recycle
circular economy definition:
where materials never become waste, reducing new material dependency
what are the two components of a circular economy?
biological nutrients
technical nutrients
what’s meant by biological nutrients?
living
organic, non toxic materials
re-enter ecosystem without causing environmental harm
what’s meant by technical nutrients?
man made materials
designed to be used at the same high initial quality with minimal environment effects
what’s an example of a technical nutrient?
polymers and alloys
what are the 3 circular design principles?
- preserve
- optimise resource yields
- system effectiveness
what’s a composite?
materials made up of multiple elements, mix
cant be recycled
what is biomass?
burning of organic matter that’s produces steam, which then turns generators creating energy
advantages of biomass:
cheap
available source
long term and sustainable
disadvantages of biomass:
carbon neutral
- releases the CO2 which was trapped
what is geothermal energy?
fracking, to release steam
- water drilled at high pressure into the earths core
- pushing out steam
where is geothermal energy often used?
in volcanic region, easy access to tectonic plates
advantages of geothermal energy:
provides hot water and heat to nearby homes
disadvantages of geothermal energy?
extremely expensive to set up
risk of setting earthquakes
what’s the common advantage of renewable energy’s?
infinite supply
common disadvantages of renewable energy’s?
expensive
eye sore
large land / destroys it
