rasvatööstus

Rasvatööstus, often translated as the fat industry or rendering industry, refers to the sector involved in the collection, processing, and utilization of animal fats and oils. This industry plays a crucial role in the circular economy by converting by-products from animal slaughterhouses, butcher shops, and food processing plants into valuable commodities. These by-products, which include animal carcasses, fat trimmings, bones, and used cooking oils, would otherwise be discarded as waste.

The primary process within the rasvatööstus is rendering, which involves heating these materials to separate the fat from protein and water. This can be done through wet or dry rendering methods. The resulting rendered fats and oils, known as tallow, lard, or grease, have a wide range of applications. Historically, they were a staple in soap making and candle production. Today, their uses have diversified significantly.

Rendered animal fats are commonly used in the production of animal feed, providing essential nutrients and energy. They are also a key ingredient in the manufacturing of biodiesel, a renewable fuel source. Furthermore, these fats find applications in the cosmetics and personal care industry, as well as in the production of lubricants, paints, and other industrial products. The efficient management and processing of animal by-products by the rasvatööstus contribute to reducing environmental impact and maximizing resource utilization within the broader agricultural and food sectors.
