Coal from a landfill can be recycled into concrete, which can then be used to build houses.
But it’s a tricky process, as it takes years to break down the coal.
This means that concrete from the landfill is often cheaper to use.
So you might be surprised to find out that this cheaper concrete can be made into a cheaper plastic recycling material.
BBC News: How much does a single square foot of concrete cost?
How much is the plastic equivalent of a square foot?
The answer depends on how much the waste is recycled.
BBC reporter Mark Allen explains how the waste can be used.
Plastic Recycling: How Much Is the Plastic Equivalent of a Square Foot?
1,200,000 cubic metres or about 1,000,000 litres of plastic waste A square metre is equal to 2.9 square feet 2.89 square metres is equivalent to 1,100 square feet 1,110 square metres would be equivalent to about 830,000 square feet – a total of about 1.6 billion cubic metres – Plastic recycling Plastic waste is produced by the burning of wood or coal and can be reused to make other materials.
The plastics used in plastics are mainly recycled from paper, glass and metal.
Plastic recycling is also used in other industries, such as plastics, cardboard and cardboard products, and plastic packaging.
Some plastics can be transformed into other materials using processes such as polymerisation and biodegradation.
Plastic materials can be converted to paper by heating them at temperatures of up to 100 degrees Celsius (212 Fahrenheit).
A plastic film can then form on a plastic surface.
Plastic can also be used as a building material.
A plastic pipe is used to make the plastic roof of a building.
There are also a range of other materials that can be turned into plastics.
The plastic used in these products is typically polyethylene, a synthetic polymer that is used in the production of car parts, plastics and rubber.
Plastic bags are often used in packaging.
Plastic from plastic packaging can also form into plastics and paper products, such the polystyrene film used in plastic bags.
These plastic materials can then either be reused for other products or recycled.
Plastic packaging has the advantage of not requiring large amounts of water to form a solid product.
The polymer can then simply be melted into a solid form.
Plastic bottles can be manufactured in a similar way, although they must contain water and a certain amount of salt.
How Much Does a Square Meter of Concrete Cost?
A square meter is equal the area of an acre.
An acre is about 30 square kilometres.
A square foot is equal 3.4 cubic metres.
1,800 cubic metres is equal about 15,000 gallons.
So a cubic metre of concrete can cost around £11.50.
The cost of a cubic meter of concrete is equal: (a) to £11,50 + (b) to the cost of the landfill + £11 to the waste cost per cubic metre (0.6 cubic feet of waste = 0.6 square metres).

A plastic waste is essentially waste material that has been separated into smaller pieces.
This has the same properties as concrete, but it is cheaper.
It can be broken down and used to create more plastic.
The waste that has already been removed from the landfills is usually discarded in landfill sites and recycled into plastic.
This process produces waste that is less harmful to the environment and more expensive to recycle.
