AfOR (Association for Organics Recycling) is a UK-based organization that provides certification services for compostable products. The AfOR compost certification rules highlight the circumstances under which compost can be considered a ‘product’ and when it is regarded as ‘waste’. Any composts sold in England and Wales for any use must comply with the PAS 100 & CQP (the British Standards Institution's Publicly Available Specification for Composted Materials and the Environment Agency and Waste and Resources Action Programme's Compost Quality Protocol).
