 In addition to animal proteins, fats and oils are the other main products resulting from the rendering process. Originally used centuries ago to make soap and candles, animal fat (or tallow) is now refined to yield products such as stearic and oleic acids and glycerin, used in dozens of commercial applications.
Tallow’s chemical structure can also be altered to produce fatty acids, maybe the most versatile derivative of rendered fats. Fatty acids are already used in plastic goods, cleaners and printers' inks, and researchers see an exciting range of possibilities for future applications.
Feed grade fat, or yellow grease, is also produced through the rendering process, but is more commonly produced by recycling the used cooking oil we pick up from restaurants and food processing facilities. This product is used as a high-energy liquid feed additive in livestock and pet foods. It is also increasingly being used as a source for renewable energy, either as raw stock for bio-fuels, or as fuel to power several of our processing facilities.
Key Benefits:
- used in numerous consumer goods
- high-energy feed additive
- derived from used cooking oil
- environmentally friendly
- can be converted and used as bio-fuel
