Recycling helps to reduce the need for landfill and more costly forms of disposal. Recycling also reduces the need for extracting (mining, quarrying and logging), refining and processing raw materials all of which create substantial air and water pollution. This helps to save energy, reducing greenhouse gas emissions and helping to tackle climate change.
If contamination is put into recycling green or brown bins it can mean a whole lorry-load of recycling can’t be recycled. This costs additional money and the waste is sent for landfill or energy recovery.
