Q

10 principles of the circular economy

A

Cycling of materials
Energy derived from renewable resources
Human activities should support ecosystems
Diverse systems are more resistant to change

Q

Explain cycling of materials as a principle of the circular economy

A

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

Q

Explain why ‘human activites should support ecosystems’ is a principle of the circular economy

A

Human survival relies on services provided by natural ecosystems
So it is important that human activites dont destroy them

Q

Explain why ‘diverse systems are more resistant to change’ is a principle of the circular economy

A

Each component of a diverse system is less likely to be important
Impact of any changes to them would therefore be smaller

Q

Explain connected systems as a principle of the circular economy

Q

Explain why ‘designing products for extended use’ is a principle of the circular economy

A

They have longer lives which reduces the oppeetuinties for material loss at the end of product life
Been thoroughly used

Q

Explain why designing products for end of life reuse is a principle of the circular economy

A

Reuse/recycling is easier if an item is designed so materials can be easily identified, sepearated and reused

Q

Explain the separation of technical and biological materials as a principle pf the circular economy

A

It is important because metals and plastics require different reprocessing methods for example

Q

Explain optimum production instead of maximum production as a principle of the circular economy

A

Matural systems usually over produce, the surplus then supports prcocesses the system relies on
This contrasts agroecosystems which aim for maximum harvestable yield

Q

Explain technology ro design new products and improve system effectiveness as a principle for the circular economy

A

Improved design increases efficiency of energy use, reduces material use and enables dismantling for re use

Q

how can agriculture be developed to support natural ecosystems?

A

Agriculture-environmental schemes
They can optimise yields whist benefiting wildlife

17
Q

How can forestry be developed to support natural; ecosystems

A

Mixed species forests of indigenous trees
Increases wildlife value

18
Q

How can fishery management be developed to support natural ecosystems?

A

Improve fishing methods so fish populations are sustainably exploited, bycatch is reduced, as is environmental damage

19
Q

How can mineral resources be developed to support natural ecosystems?

A

Extraction will always cause habitat damage
Good management will reduce the impact, as will site restoration after mine closure

20
Q

How can waste management be developed to support natural ecosystems?

A

Good waste management reduces pollution including that, that harms wildlife

21
Q

How can the principles of the circular economy be applied to water supply

A

Good management of water catchments, aquifers and water conservation
Will reduce impact sof water uses on wildlife

22
Q

How can the principles of circular economy be applied to mineral resource management

A

Increasing reserves by exploiting low-grade orders
Better design of products to extend lives
Replaceable parts with good quality spares/technical support
Reduce unnessesary use e.g. excessive packaging

23
Q

How can the principles of the circular economy be applied to waste management?

A

Repair,reuse,refurbish,recycle
Redesign to make reuse easier

24
Q

How can the principles of the circular economy be applied to pollution control

A

Move from post production treatment to non-release by changing technology/processes
Industrial synergy-waste becomes resource
Better design so waste is separated

25
Q

How can the principles of the circular economy be applied to energy supplies?

A

Use renewables and low temperature manufacturing processes
Development of storage methods to make renewables easier to use
Development of methods that improve energy densities so fossil fuels can be replaced

26
Q

How can the principles of the circular economy be applied to food production?

A

By including natural processes into nutrient supply, pest control,soil maintenance

27
Q

how can the principles of the circular economy be applied to diverse systems?

A

Diverse technical system would be more stable, like diverse systems are
E.g. societies relying on a range of renewables rather than one only

28
Q

What areas of focus has the EU aimed proposed/introduced initiatives at, to reduce environmental impacts/support the circular economy?

A

Conservation of biodiversity
Waste management/pollution control
Water
Energy
Design of manufactured appliances

29
Q

Give examples of proposed/introduced EU initiatives to support the circular economy in terms of conservation of biodiversity

A

Better protection of ecosystems and habitats
Development of green infrastructure
Better management of fish stocks
More sustainable agriculture and forestry
Better control of introduced species

30
Q

Give examples of proposed/introduced EU initiatives to support the circular economy in terms of waste management and pollution control

A

Better control of urban waste water
Minimal landfill use
More recycling of electronics/electrical appliances/batteries/packaging
More control of industrial emissions
More use of composted materials as fertilisers
Reduced food waste/use of packaging

31
Q

Give examples of proposed/introduced EU initiatives to support the circular economy in terms of water

A

More re use
Better management of the quantity and quality of resources

32
Q

Give examples of proposed/introduced EU initiatives to support the circular economy in terms of energy

A

More use of biofuels/other renewables for transport
Improved energy efficiency of fridges/freezers
Increased use of waste for energy generation
Increased use of renewables

33
Q

Give examples of proposed/introduced EU initiatives to support the circular economy in terms of design of manufactured appliances

A

Improve design so they can be repaired to extend life
So Materials can be reused/recylced
Reduced use of toxic materials e.g. in electrical appliances
More use of recylced materials in road/building construction
Easier battery replacement
Vehicle manufacture using recycled materials

34
Q

Why is it difficult for governments to implement the principles of the circular economy however much they want to protect the environment/

A

The cost of implementing these schemes is expensive
Companies in countries where these initiatives are in place are at more of an economical disadvantage than companies in countries where they aren’t in place

35
Q

How could governments implement initiative e to support the circular economy in a more effective way?

A

More even approach if groups of countries use a common approach
A group would have better coordination/regulation/monitoring of activities than an individual
As a group allows more successful and effective environmental protection- also allows countries that aren’t successful to be supported
