Value-add to livestock value chain residues South African Case Studies

The document outlines five South African case studies focused on livestock residue valorization. These include biogas installations at Zandam Piggery & Cheese and Uilenkraal Dairy, insect protein production from organic waste by AgriProtein and Khepri Innovations, and open wind-row composting at the Robertson Abattoir.

• Biogas installations at livestock facilities produce electricity, heat, and digestate, though they face challenges with capital costs and digestate management. Zandam Piggery & Cheese has a capital cost of approximately R9 million and an electrical output of ≤100 kW, while Uilenkraal Dairy has a capital cost of approximately R10 million and an electrical output of ≤400 kW.
• Insect protein production using fly larvae fed on organic waste creates high-value substitutes for soy and fish-meal, as well as soil conditioners. AgriProtein produces MagMeal, MagOil, and MagSoil, with capital costs estimated between R60 and R100 million for 100 t/day feed. Khepri Innovations operates on a smaller scale, utilizing solar energy for larvae drying and testing abattoir waste as feedstock.
• The Robertson Abattoir implemented open wind-row composting of approximately 10 t/d of abattoir and green waste, driven by tightened waste regulations and high management costs.
