The European Union's Animal By-Products Regulations (Regulation No 1069/2009) allows for the treatment of some animal by-products in composting and biogas plants (anaerobic digesters). The following article describes procedures required to allow solid outputs (compost, digestate) from composting plants and anaerobic digesters onto land in the United Kingdom.

- Category 1: Very high risk
- Category 2: High risk
- Category 3: Low risk
Category 1
Must all be destroyed, not for use in composting or biogas plants

Category 3
- Catering waste from households, restaurants
- Former food
- Much slaughter house waste e.g. waste blood & feathers
Can be used in composting and biogas plants without pretreatment
