Method for treating organic waste by larvae of hermetia illucens

The present invention relates to agricultural production. The method comprises the bioconversion of a broad range of agricultural (organic) wastes, including manure and litter, distillery stillage, brewer grains, grain wastes, unusable grains of different crops, slaughterhouse wastes, sugar industry wastes, various press cakes and meals, dairy wastes, food wastes, etc., using larvae of Hermetia illucens flies. The method for treating organic wastes comprises providing eggs of Hermetia illucens flies, next incubating the eggs and growing the larvae on a growth medium; separating the larvae from the growth medium and sizing thereof; homogenizing the organic wastes to produce a substrate having a moisture level of 70-55%; populating the feed substrate with larvae of the same size and a predetermined density; bioconverting the substrate. The stage of separating the larvae and populating the substrate with larvae of the same size and a predetermined density allows a high conversion rate of the substrate treatment and a maximum yield of the biomass on various substrates.
