Landfill
If you take a trip to the tip, you may see lots of seagulls.

Landfill

Landfill is a sub topic of your geography studies of waste and pollution and the GCSE syllabus requires that you show an understanding of similarities and differences between the production and handling of a variety of waste products and pollution. You also need, as usual, to be aware of the differences between the richer and poorer countries.

The quantity of waste and pollution varies between countries. In the richer countries, consumerism is much greater as the population has a higher disposable income. As a result, they produce a lot of waste that goes into landfill sites. The UK produces over 500 kg of waste per person per year where poorer countries like Estonia and Poland produce only half of that. The world's poorest countries produce only about 100 kg of waste per person per year.

1.
Which of the following does not end up in a landfill site?
Waste water
Old mattresses
Certain plastics
Painted wood
Local authorities make an effort to ensure that anything that can be recycled or reused stays out of landfills. Landfills are intended for solid waste only
2.
Which of the following gases is a danger to homes near a landfill site?
Methane
Carbon monoxide
Low level ozone
Nitrogen oxides
The other three gases are associated with air pollution from combustion
3.
One of the reasons that LEDCs produce less waste than MEDCs is that ...
people buy food from supermarkets
people buy food from street traders
people use a lot of disposable items
it is impossible to buy disposable items
There is little or no packaging for disposal, not like when you buy from a supermarket where almost everything is packaged
4.
Why must a landfill site be chosen carefully?
So that red squirrels don't get poisoned
So that farmers don't get annoyed
So that local people can't see the refuse trucks delivering the waste to the site
So that water supplies are not contaminated
Quite often, old quarries are used for landfill
5.
As a poor country becomes wealthier, the amount of waste reaching landfill sites increases because...
the rural population increases
the rural population decreases
consumer items are bought and replaced more frequently
more cash crops are grown
This is possible because the disposable income of the population is higher
6.
Why is consumerism greater in some countries than others?
There are more things available to buy in the shops
The packaging is more attractive
In MEDCs, disposable income is higher
Some governments put people in prison for not spending a lot of money
In wealthy countries, there is more money to spend and consumer items are plentiful. In poorer countries, the opposite is true
7.
One way to reduce the amount of material going to landfill is ...
to dump it at the side of the road in a layby
to put it into the nearest river so that it gets washed out to sea
to hide it somewhere
avoid using packaging when it is not actually needed
Some packaging is used for no other reason than items are easier to move around and easier to stack in shops and supermarkets. Some packaging, e.g. for electrical items, is essential for protection and to keep all the different parts (like the charger, remote control, SIM card and leads) together. It is not really possible to reduce packaging to zero
8.
Some local councils have established combined heat and power systems. Why?
They keep the council offices warm in the winter months
They use burnable waste so less material needs to be sent to landfill
It encourages people to reuse and recycle items
It is pollution-free
Burnable waste is burnt in incinerators in controlled conditions to produce as little air pollution and ash as possible. The heat is used to produce electricity for the National Grid and hot water that can be piped to nearby buildings for heating
9.
When a landfill site is full ...
it is landscaped
it is surrounded by a barbed wire fence with 'Keep Out' notices
it is left exactly as it is for everything to rot down so that it can be used again in the future
the local council comes along and empties it
It is covered with soil and planted with grass and trees for hygiene and safety
10.
Why are disposable items like razors and babies nappies used more in wealthier countries?
They are more readily available
Even though they are more expensive in the long term, populations in MEDCs have enough money to regularly buy them
They are usually more convenient to use
All of the above
Since these are not designed to be reused or repaired, disposable items create more waste
