// Animal by-product processing

Carcass preparation -
The foundation for quality

Animal carcass & slaughter by-product processing begins with the delivery of raw materials, which are categorized upon acceptance within the EU:

• Category 1: Material with highest risk - disposal.
• Category 2: Material with risk of non-communicable diseases - not for feeding.
• Category 3: Material that is generally no longer suitable for human consumption.

The delivered materials are then unloaded into collecting troughs, which enable hygienic interim storage of the materials and at the same time prevent contamination of the environment.

In a two-stage size reduction process, the animal body parts are first reduced to around 50 mm by a coarse crusher and then to around 25 mm by a fine crusher. This enables efficient further processing, after which the material passes through a metal separation system. Metallic impurities are removed from the material by means of inductive separation.

From raw materials to fat

After sterilization, the material is separated into its main components. In this process, meat, bones and fat are separated from each other. This is done using separation plants that work with different mechanical processes. Depending on the category of the raw material and the desired end products, the separated components are further processed in different ways:

• Bones: Are further crushed and ground into bone meal, which can be used as fertilizer or, in certain cases, animal feed.
• Fat: Is extracted and purified to make it usable for the production of soap, cosmetics or biodiesel.
• Meat and offal: Are processed into animal feed or used for other industrial purposes.
