Waste Flashcards
Define the following:
- Consumer society
- Throwaway society
- Landfill
- Incineration
- Where people continually buy new things - Where people throw things away, even if they are still working - Where waste is buried underground - When waste is burned
Define domestic waste
Domestic waste is waste produced in the home
What are the 3 types of domestic waste?
- White goods
- Packaging
- E-waste
Describe the differences in waste production by HICs and LICs
HICs:
- A lot more waste
- More newspapers
- More e-waste
LICs:
- Less glass
- Less waste
- Less packaging
Why do some countries produce more waste that others?
- HICs produce packaging for advertising and transport - Low literacy levels therefore less newspapers - Throw away things before the end of their life - More money therefore buy more
Use a case study to explain how waste is recycled locally
- Green waste
- Textiles
- Mixed cans
- Glass and cardboard
- Green and food waste - sent to Ardley to be turned into fertiliser by anaerobic digestion - Textiles - sent to Oxfam to be sent to LICs - Mixed cans - sent to Oxfam to be recycled - Glass and cardboard - sent to Enstone to be recycled
How can the following products be recycled?:
- Paper
- Glass bottles
- Aluminium cans
- Vegetable peelings
- Turned into pulp, then squeezed out into paper - Broken down into cullets and then used for new glass - Shredded, melted and turned into steel rings - Composted
Use a case study to explain how HICs dispose of different types of waste
- Packaging
- Nuclear
- E-waste
- Domestic
- Packaging - green dot scheme where produced can be returned to manufacturer, more packaging increases cost of green dot
- Nuclear - buried in old mines in Saxony
- E-waste - sent to Ghana
- Domestic - recycled or
sent to incinerators, pay
as you throw
What are the advantages and disadvantages of landfill?
Advantages: - Produces methane which can be burnt as a fuel source - Anything can be buried - Can be built on when finished with
Disadvantages: - Running out of space - EU tax on landfill - Can pollute water supplies - Visual pollution and smells
What are the advantages and disadvantages of incineration?
Advantages: - Little waste produced - Ash can be used on roads and in construction - Can be used to produce electricity
Disadvantages:
- Concern that emissions
can cause cancer
- Visual pollution
Define the following and give an example:
- Renewable resources
- Non-renewable resources
Renewable: a resource that won’t run out, eg. wind
Non-renewable: a resource that will eventually run out
What are the advantages of producing and developing one renewable and one renewable resource?
Renewable (wind): - Wind is free - No greenhouse gases - Can be used on land and at sea
Non-renewable (coal): - Coal is found in many countries - Relatively cheap to mine - Relatively easy to convert
What are the disadvantages on the global environment of one non-renewable and one resource?
Renewable: - Unsightly - Greenhouse gases - Disturb migration of birds - Doesn't work in too much wind or not enough
Non-renewable: - Waste-heaps - Deep mining can be dangerous - Acid rain is a problem - Greenhouse gases emittes
Explain why the energy mixes varies
- HICs have more money so can afford to use more energy - HICs have more money so can afford to buy more things which need energy - Those places with a higher population will need more energy - Some countries have their own sources of energy so are able to use it more
Explain how energy is being wasted domestically and industrially
- Lights left on
- TVs on standby
- Windows open when
heating is on - Lack of insulation
