Using Larvae to Convert Food Waste into Animal Feed

JM Green uses larvae in its treatment technology to convert food waste into a nutritious animal feed, reducing the need to trawl for fish.

With the use of 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 process the organic waste, after which the larvae are separated from the residuals, and then sterilized and washed. The larvae are sold as high-protein animal feed in agricultural production, presenting a viable alternative to animal protein used in regular poultry feed and fish farming.

China produces 60 million tons of food waste every year, equivalent to the food of 200 million people.<sup>1</sup> According to JM Green, their technology can convert 100 metric tons of organic waste into 20 metric tons of larvae and 40 metric tons of fertilizer. The company currently processes 110 metric tons of organic waste per day.

Relevance of solution

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.2 The solution helps address food waste and overfishing by bringing a highly nutritious insect protein to the livestock feed market.

Triple Bottom Line


By reducing the need for fishmeal trawling, the solution can help replenish the ocean’s natural stocks.


In contrast to other fly species, the Black Soldier Fly does not carry or spread disease when processing organic waste.


Insects are a viable alternative to traditional livestock feed made of fishmeal and land-and plant-based proteins, which are either increasingly expensive to produce or contain less relevant amino acids.
