Animal By Products Regulations

The Animal By Products Regulations 1774/2002 originally came into force in 2003, were replaced by Regulations 1069/2009, and have subsequently been amended and consolidated as Regulation EU 142/2011. The Regulations cover the movement, use and disposal of any substances that contain materials of animal origin that people do not consume. The Animal By-Products (Enforcement) (Wales) Regulations (ABPR) 2011 is the enforcing legislation in Wales. They contain the national standards for AD plants as well as powers for inspectors, approval controls and appeals procedures.

Animal by products (ABP) are classified into three categories:

Category 1 – Highest risk materials and international catering waste. This material cannot be treated using anaerobic digestion and needs to be incinerated or rendered

Category 2 – High risk animal by products. This material cannot be treated using anaerobic digestion unless it has been pressure cooked to the European Standard (133°C/3 bar/20 minutes). However, although the following materials are listed as category 2 material they can be used in AD plants without ABP approval – Manure, Digestive Tract Content, Milk and Colostrum

Category 3 – Low risk animal by products. This material can be treated via a number of routes including anaerobic digestion. This material includes raw meat intended for human consumption, waste from food manufacturers and retailers, eggs, and other by products that do not show signs of transmissible disease. All UK derived catering waste (i.e. from domestic and commercial kitchens) where meat and non meat fractions are combined is also covered as Category 3 material

In order to treat Category 3 material an AD facility must be approved and incorporate a number of criteria. Further informatio can be found at

The Welsh Regulations state that an AD plant handling ABP material cannot be located on the same premises as livestock. This means that there needs to be a complete separation between the AD plant and the farm. A separate area has to be identified with separate access arrangements and no means of cross contamination.

The precise requirements under the ABPR are site specific and therefore early discussions with the Animal Health and Veterinary Laboratories Agency (AHVLA) (the Government's executive agency primarily responsible for ensuring that farmed animals in Great Britain are healthy, disease-free and well looked after) who are responsible for the issue of Animal By Product Approval is essential.

Local Authorities actually enforce the ABP Regulations and carry out risk assessed compliance visits.

If the plant is approved under the ABPR, the digestate can be spread on land as regulated by the ABPR. Where that land is pasture (land that is intended to be used for grazing or cropping for animal feeding stuffs), livestock must not be allowed access to land to which compost or digestion residues have been applied for the following minimum time periods: (a) in the case of pigs, eight weeks; (b) in the case of other farmed animals, three weeks. Similarly, animals must also not be fed with anything cropped from land to which compost or digestion residues have been applied, for the same time periods (eight weeks for pigs, three weeks for other farmed animals). You should also consult the requirements for land spreading of digestate under the Environmental Permitting Regulations and the PAS 110.
