Animal by-products

Animal by-products (ABPs) are generated during the slaughter or death of animals or during the processing of products of animal origin.

In Slovenia, more than 150 tons of animal waste are produced daily. At KOTO, we ensure their safe collection and proper processing, so they no longer pose a threat to the environment.
