Landfill is a type of biomass; biological material used as a renewable energy source. It usually comes from waste plant and animal matter. When they decompose, they produce a mixture of methane and carbon dioxide, both greenhouse gases. This mixture is known as ‘landfill gas’.
These green house gases escape into the atmosphere if not collected. Landfill gas is a valuable resource and can be extracted. It can be used as a clean and safe energy source to produce electricity or heat.
