to the content of natural antioxidants and immunomodula- tory agents in the product, such as – chitin and melanin,” Istomin reveals. ZooProtein plans to enter the market of not only chicken feed, but also of unconventional poultry feed, including ducks, turkey, quail and so on. Also use in pig feed and feed for valuable fish species is on the radar. At the same time, the processed substrate, when the larvae is separated after harvesting, can be used as a mineral fertiliser, Istomin notes.
Huge savings A preliminary study showed that with the company’s tech- nology, an average poultry farm in Russia can reach annual savings of about Rub 40 million (US$800,000). “A poultry farm in Russia generates quite some waste, including dead chicks, by-products and so on. Russian legislation obligates a farm to dispose waste, which comes at a cost. On the other hand, most poultry farms in Russia are cultivating crops and for this purpose purchase fertilisers to be used at fields. Finally, the sources of protein in poultry feed are also expen- sive. Our technology brings savings in each of those seg- ments,” Istomin says. ZooProtein posted “a calculator of savings” on its website, where every farm can estimate how much money it can save, when installing the larvae rearing house. On average, it shows economy of Rub 9 (US$0.15) per kg of re-processed waste. “It nearly takes 10kg of waste to produce 1kg of protein-rich biomass. The production cost for 1kg of biomass nowadays reaches Rub 30 (US$0.5) per kg, but it can be reduced further until the technological pro- cess is optimised. Furthermore, the production cost, as well as the profitability depends on the size of poultry farm,” Istomin explains.
A revolution of minds Istomin states that at first Russian sanitary bodies were re- luctant to see the advantages of the new technology. This is partly because the national regulations in the area of feed safety haven’t been saying a word about the use of insects in animal feed. ZooProtein had to convince the authorities as well as the farmers that biomass derived from waste, re-pro- cessed by the common greenbottle fly is safe. Not an easy task when the fly itself is considered as something dirty and unhealthy. However, Istomin saw “a revolution in minds” af- ter he shared the science behind the process. “It is a remark- able fact that the maggots can disinfect waste. We tested it on the re-processing of waste, infected with bacteria of the 4th
class (highly pathogenic), that is salmonella and other
The biomass of processed maggots consists of 50% protein and 30% fat, according to official company information.

causative organisms. The flies turned it into a fully clean product,” Istomin notes. The company plans to shape up the technology in 2018 and install it at most of the local poultry farms shortly after. At the moment, the main goal is to achieve the full automation of all processes – so the system could operate without any human participation at all.
