What is Rendering?

Rendering animal by-products (ABP) became a widespread and efficient practice in the 20th century meat industry, a practice dating back to ancient times when animal skins provided shelter and clothing and tallow was made into soap and candles. 

It is a cooking or drying process that destroys pathogens and stabilises animal by-products, removing the moisture and separating the fat and protein meal components into a range of marketable products. 

A typical rendering process is shown in Figure 1 and includes size reduction, cooking and separation of fat from protein.

KEY BENEFITS

• All categories of ABPs can be rendered

• Strictly controlled bio-secure processing

• High value, low carbon products derived

• No waste

Rendering is the most bio secure and most sustainable method of processing animal by-products, deriving useful low carbon products used in the manufacture of animal feed, pet food, pharmaceuticals, organic fertilisers, biofuels, cosmetics and oleochemicals.
