Landfills are huge holes underground. These holes get filled by waste from homes and industry. Everyday the rubbish gets squashed so it is compacted. When the hole is full it gets covered with a layer of soil or dirt and it can be used as a playground, golf course or park.

Methane gas is produced by landfills. It is one of the "green house gases". Methane gas is smelly and highly explosive. It damages the enviroment, ozone layer and it is poisonous.

There are two ways of dealing with methane gas. It can either be burned off. This is called "flaring" or used as energy. It gets sucked up a pipe, if it is enough quantity and the quality is good it can be used to make electricity.
