The quality protocol for the production and use of quality outputs from anaerobic digestion of source-segregated biodegradable waste.

This Quality Protocol was funded by Defra as a business resource efficiency activity. It 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 both England and Wales. It sets out criteria for the production and use of quality outputs from anaerobic digestion of source-segregated biodegradable waste.
