What is Rendering?

Rendering is the process of transforming animal by-products — such as trimmings, bones, feathers, blood, and offal — into valuable protein meals, fats, and oils. Instead of going to waste, these by-products are processed at high temperatures to separate fat from protein and eliminate pathogens.

​

The result? Safe, nutrient-rich ingredients used in animal feed, pet food, and aquaculture diets.

At PSI, we supply rendered ingredients such as:

  • Meat and Bone Meal (MBM)

  • Poultry Meal

  • Feather Meal

  • Blood Meal

  • Fish Meal

The Benefits of Rendering

Rendering is a vital link in the global food chain and supports multiple industries while offering powerful environmental benefits:

​

Benefits

Impact

Waste Reduction

Prevents millions of tons of organic by-product waste from landfills

Carbon Savings

Reduces methane emissions vs. disposal methods like landfilling or composting

Energy Efficiency

Recovered fats and oils can be used as biofuels or for renewable energy

High-Quality Nutrition

Produces protein- and mineral-rich meals for pet food, livestock, and fish

PSI’s Role in Sustainable Protein Supply

At Protein Solutions International (PSI), rendering is at the heart of how we supply clean, traceable, high-quality protein to Africa and beyond.

We work exclusively with certified rendering operations in the UK and South Africa (Leo Group & BJK Industries) that operate under strict environmental, safety, and quality standards.

​

By importing rendered proteins in bulk and supplying them locally from in-country warehouses, PSI ensures:

  • Lower environmental footprint per ton delivered

  • Reduced reliance on traditional feed crops (like soy or maize)

  • Local availability of global-quality products for pet food, poultry, fish, and livestock producers

Why Rendering is the Future of Sustainable Protein

The demand for protein is rising — but so is pressure on land, water, and natural resources. Rendering offers a scalable, eco-efficient alternative by:

  • Extending the value of the existing food chain

  • Minimising the use of virgin resources

  • Supporting food security through responsible feed ingredients

PSI helps your business meet nutritional needs while supporting sustainability goals.
