EnviroFlight uses the co-product from breweries, ethanol production, and pre-consumer food waste as a feedstock for Black Soldier Fly larvae (Hermetia illucens). The larvae feed off and bioconvert the material. By doing so, the frass — the waste product created by insects after digesting the feedstock — becomes a high protein, low fat feedstuff for omnivorous species such as tilapia, freshwater prawns, catfish. The material is also beneficial as a protein source for poultry, swine and cattle.
The larvae are used as a high protein, high fat ingredient for carnivorous fish including rainbow trout, perch, bass, and bluegill. The larvae are cooked, dried and converted into a meal that is 40% protein and 46% fat. The oils can be extracted, which boosts the protein content to above 70%. We are currently producing and testing aquaculture feeds, as insect meal acts as a fish meal replacement. Enviroflight has developed and tested a number of feed formulations using insect meal and other locally available ingredients for complete diets for multiple species of fish.
Key to our process is the prevention of ammonia creation in the frass by stabilizing the material immediately after the insect larvae consume the feedstock. This keeps the nitrogen fixed and eliminates odor; it also mitigates the formation of molds and mycotoxins. The frass is also beneficial as a natural, animal-safe fertilizer. The N-P-K value (nitrogen – phosphorous – potassium) level is 5% – 3% – 2%, and as such is ideal for vegetable growth.
The entire system is comprised of proprietary bioreactor, breeding, and nursery systems. The system is designed to be located anywhere in the world and optimized for operation in developing nations. The breeding system is able to produce mating events and eggs in any climate. Because of this there is a continual source of eggs in all weather conditions.
