Quality protocols set out end of waste criteria for the production and use of a product from a specific waste type. Compliance with these criteria is considered sufficient to ensure that the fully recovered product may be used without undermining the effectiveness of the Waste Framework Directive and therefore without the need for waste management controls.
The Quality Protocol was developed by the Environment Agency and WRAP (Waste & Resources Action Programme) in consultation with Defra, industry and other regulatory stakeholders. The Quality Protocol is applicable in England and Wales. It sets out the end of waste criteria for the production and use of biomethane arising from the degradation of organic wastes in a landfill site or anaerobic digestion plant, for injection into the gas grid or use in an appliance suitably designed and operated for natural gas, such as vehicles, turbines or heating appliances.
