Collecting and processing animal by-products

Handling animal by-products (ABP) and public services

Complete solution in handling ABP includes collecting and processing Category 3 ABP and providing a general economic service for Category 1 and 2 ABP. 


Animal by-products (ABP) come as the result of animal slaughter or death i.e. processing animal products. This can include entire carcasses or animal parts, products of animal origin or other products obtained from animals that are not intended for human nutrition. If they are incorrectly used or disposed of, they can be a threat to the health of people and animals and can harm the environment, which is why the handling of such material is regulated by both EU and Slovene legislature.

They are grouped into three different categories, each indicating a level of risk for public health and health of animals: 


  • Category 1 ABP are materials containing potentially dangerous substances and are therefore processed and eliminated as waste through incineration. This most commonly includes infected or possibly infected animals i.e. containing prohibited substances, which can act as dangerous pollutants. Category 1 ABP also includes carcasses of pets, ZOO animals, and catering waste from international transport.
  • Category 2 ABP are also materials containing potentially dangerous substances. They include dead animals, digestive tract content, floating layers, rotten meat, faeces etc. Category 2 ABP is processed similarly to Category 1 ABP. 
  • Category 3 ABP are edible substances of animal origin, but are commonly not used and discarded due to commercial reasons. This includes e.g. animal parts (hides, hooves, horns, pig bristles, bird feathers, and blood), excess products from the food industry, eggs, milk, fish,etc. Appropriate processing of Category 3 ABP produces substances that can used as pet food and fertiliser, and quite often in the technical, pharmaceutical, and cosmetics industries.

Slovenia produces more than 150 tonnes of animal waste per day. KOTO provides a safe way of collecting and processing the waste, so that this waste no longer poses a threat to the environment.

Collecting and processing Category 1 and 2 ABP

Producers of Category 1 and 2 ABP must hand over the hazardous material to authorised processors with the permit for handling this type of substances. In Slovenia, KOTO signed a five-year concession agreement with the state for providing the mandatory state commercial public service of handling Category 1 and 2 ABP. 
All relevant information regarding the pickup of C1 and C2 ABP is available in the Instructions and information for users of the public service >>
