Green waste is biodegradable waste that can be composed of garden or park waste[1], such as grass or flower cuttings and hedge trimmings, as well as domestic and commercial food waste. The differentiation green identifies it as high in nitrogen, as opposed to brown waste, which is primarily carbonaceous.
Green waste is often collected in municipal curbside 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.
