Green waste

Green waste

Green waste is biodegradable waste that can be comprised of garden or park waste [ [http://www.winwaste.com/CaseStudy3.aspx Green waste removal case study] ] , such as grass or flower cuttings and hedge trimmings.

Green waste is often collected in municipal kerbside collection schemes or through private waste management contractor businesses and subject to independent audit.

Biodegradable

The green waste fraction of the overall waste stream is important as a biodegradable waste. If the waste is not either composted or anaerobically digested and it is disposed of in landfill it is an environmental liability.
Biodegradable waste in landfill breaks down to biogas containing methane, which if not captured is a potent greenhouse gas and contributes to global warming

Biofuels

Biogas captured from biodegrable green waste can be use as biofuel.

Also green waste can be used as non food crop to produce cellulosic ethanol.
