Sanergy harvests waste from toilets it operates in a franchise network in Nairobi's slums and feeds it to fly larvae, which become high-quality animal feed. HARVESTING INSECTSAs the world looks to feed 10 billion mouths by 2050, businesses harvesting insects — either for human consumption or as animal feed — are growing. Fast food giant McDonald’s and US agricultural powerhouse Cargill Inc are among many large companies studying the use of insects for chicken feed to reduce reliance on soy protein in the $400 billion-a-year animal feed business. That produces two products for farmers: fertiliser and animal feed. The larvae are then sold to animal feed millers, who grind them into powder mixed with other ingredients to create a balanced diet for poultry, pigs and fish.
