Green waste

Green waste is biodegradable waste that can be composed of garden or park waste, 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.
