Animal by-products and food waste

Disposing of animal by-products

Guide

If you have animal by-products, you must send them to approved premises for treatment or disposal. Ideally, different categories of animal by-product should be handled at different sites - see animal by-product categories.

Disposal of category 1 material

Category 1 material must be disposed of by:

  • direct incineration
  • rendering - followed by incineration or landfill

See guidance on incineration and rendering of animal by-products.

International catering waste may be disposed of at a landfill site authorised by the Divisional Veterinary Office.

Disposal of category 2 material

Category 2 material must be disposed of by:

  • direct incineration
  • rendering or other authorised treatment process - followed by incineration, landfill, composting or biogas treatment

Category 2 material can be pressure-rendered and then used for the production of organic fertilisers and soil improvers. It can also be pressure-rendered and used in an approved composting or anaerobic digestion plant.

Find out more about composting and anaerobic digestion of animal by-products.

A very limited number of category 2 materials (manure, digestive tract content, milk and milk-based products and colostrum) may be applied directly to land without processing provided there is no risk of transmitting a disease.

Disposal of category 3 material

Category 3 material must be disposed of by:

  • incineration
  • rendering - followed by incineration or landfill
  • anaerobic digestion
  • alkaline hydrolysis plant
  • composting or biogas plant

Category 3 material can be rendered for the production of pet food and organic fertilisers or soil improvers. Rendered category 3 material can also be used in the production of animal feedingstuffs, though there are some restrictions in place.

Certain category 3 material such as raw milk, colostrum and products derived from these can be applied directly to land provided there is no risk of transmitting a disease. Shells from shellfish and eggshells may be applied to land in accordance with national rules.
