Renderers:

Renderers collect animal mortalities, animal and food by-products and waste materials from animal production facilities, slaughter houses, packing plants, supermarkets, butcher shops and restaurants. Renderers use a cooking process to remove moisture and kill harmful bacteria. This allows animal and food waste products to be turned into useful commercial goods, including tallow, protein meals, such as meat and bone meal, and yellow grease for use in animal feeds, fertilizers and industrial applications. Many renderers also service the restaurant industry by removing used cooking oil and reprocessing it into an animal feed ingredient.
