Topic 14: Circular Economy Flashcards
What does the circular economy involve?
An analysis of human activities/ assessment of how using the principles of natural systems would create more sustainable lifestyles
what is the circular economy?
An economic system based on the reuse and regeneration of materials/products especially as a means of continuing production in a sustainable way
10 principles of the circular economy
Cycling of materials
Energy derived from renewable resources
Human activities should support ecosystems
Diverse systems are more resistant to change
Connected systems
Design products for extended use and for end of life reuse
Separation of technical and biological materials
Optimism production rather than maximum
Technology to design new products/improve system effectiveness
Explain cycling of materials as a principle of the circular economy
Biogeochemical cycles involve interconnected physical and biochemical processes where the waste from one processes is the raw materials for another
This way there is no resource depletion or build up of wastes
Explain energy being derived from renewables as a principle of the circular economy
Almost all natural processes are driven by renewables e.g. solar
Explain why ‘human activites should support ecosystems’ is a principle of the circular economy
Human survival relies on services provided by natural ecosystems
So it is important that human activites dont destroy them
Explain why ‘diverse systems are more resistant to change’ is a principle of the circular economy
Each component of a diverse system is less likely to be important
Impact of any changes to them would therefore be smaller
Explain connected systems as a principle of the circular economy
Natural systems are usually connected wen the waste of one is the raw material of another
Explain why ‘designing products for extended use’ is a principle of the circular economy
They have longer lives which reduces the oppeetuinties for material loss at the end of product life
Been thoroughly used
Explain why designing products for end of life reuse is a principle of the circular economy
Reuse/recycling is easier if an item is designed so materials can be easily identified, sepearated and reused
Explain the separation of technical and biological materials as a principle pf the circular economy
It is important because metals and plastics require different reprocessing methods for example
Explain optimum production instead of maximum production as a principle of the circular economy
Matural systems usually over produce, the surplus then supports prcocesses the system relies on
This contrasts agroecosystems which aim for maximum harvestable yield
Explain technology ro design new products and improve system effectiveness as a principle for the circular economy
Improved design increases efficiency of energy use, reduces material use and enables dismantling for re use
What activities can be sustainably developed by applying the principles of the circular economy?
Land uses that support natural ecosystems
Water supply
Mineral resource management
Waste management
Pollution control
Energy supplies
Food production
Diverse systems
How can urban development support natural ecosystem?
Management of green spaces,gardens and buildings
Allow wildlife to colonise
