Using Larvae to Convert Food Waste into Animal Feed

Using black soldier flies, JM Green turns food and organic waste into a nutrient-rich animal feed and organic fertilizer. Food waste is collected, automatically sorted and crushed before being put into large containers filled with black soldier fly larvae. The larvae consume and process the organic waste, after which the larvae are separated from the residuals, to be sterilized, washed and packaged. The larvae are sold as high-protein animal feed, presenting a viable alternative to conventional animal and fish proteins typically used in feed for poultry and fish farming.

China produces 60 million tons of food waste every year, equivalent to the food requirements of 200 million people. According to JM Green, their technology can convert 100 tons of organic waste into 20 tons of larvae and 40 tons of fertilizer. The company was processed 150 tons of organic waste per day in 2016.

Why you should care

Statistics show that 30 to 50% of the world’s annual food production is wasted, while the global fishing fleet is two to three times larger than the oceans can sustainably support. A significant portion of the proteins used in livestock and fish farming feeds come from trawled fish. This solution helps address food waste and overfishing by growing highly nutritious insect protein from food waste, which is then used in the livestock and fish feed market.
