![]() “An ingredient has to be either Generally Recognized as Safe (GRAS) or it must be reviewed and approved by the US Food and Drug Administration (FDA). However, the company also needs to demonstrate the safety and utility of its feed to comply with regulatory requirements. Olivier said that Prota Culture has also produced fish feed ingredient at the Oceanic Institute in Hawaii and is in discussions to commence feeding trials on tilapia and shrimp. In 30 years, Hawaii’s annual production of eggs has gone from 229.3 million in 1979 to less than 5.9 million in 2010 (USDA 1979, 2010).Ī local production of a cheap protein source for poultry feed could revitalize the sector, making the islands self-reliant in terms of supplying eggs and chicken. No soy or corn is grown in Hawaii, and, the ever increasing freight cost for imported feed has made purchasing it prohibitive, with the net result being a once vibrant poultry industry is now severely curtailed. He said that CTAHR based PhD students will explore the prepupae’s use in both standard and tropical poultry diets. It’s a small study but, already, we can see that egg production has been phenomenal,” said the entrepreneur. “We are currently conducting a USDA feed trial in Maui with 120 birds. Olivier said Prota Culture is working in tandem with Hawaii’s College of Tropical Agriculture and Human Resources (CTAHR)’s Bioenergy and Environment Research Group to trial the prepupae yielded by the BSF larvae as feed for layers. But before we think about marketing the units, we have to validate the process, and evaluate performance over one week, three months or six months,” said the CEO. “There is a significant amount of interest from commercial parties in the reactor technology. ![]() The land space required for a production unit would be around 14 square feet (1.3 square meters). The company uses 180kg of food waste per day to feed its four pilot scale reactors. The technology allows for commercial quantities of diverse organic materials to be processed daily without needing to shred the material, or analyze it for nutrient or moisture content,” said Olivier. “Our system, unlike ones that rely on thousands of shallow trays for insect farming, is not capital or labor intensive either - the operator only has to load the unit with feedstock to its maximum level once a day. Subsequently, the larvae don’t just reside then on the top layer of the feedstocks, as they do in other organic material transformation methods, but are eating throughout the entire reactor, enabling a level of bioconversion efficiency previously unseen and resulting in minimal compost production, he added. So, in effect, we have learnt how to slow down the food waste composting process in a reactor, giving the larvae enough time to catch up,” Olivier told feednavigator. “What we have done is biostabilize the waste bioconversion process, through homeostatically controlling all the parameters in our reactors through a sensor board, meaning we avoid the conditions that allow a build-up of thermophilic bacteria that start the composting process. The US Department of Agriculture (USDA) is backing its bid to restart local production of poultry feed in Hawaii, and last week saw the company awarded $75,000 from US non-profit group, Energy Excelerator, towards its research. Prota Culture has raised over $1million in grants and funding from multiple sources, to develop its novel bioconversion technology. Policymakers and the investment community seem to agree. I can go so far as to say that our method represents the paradigm shift in insect farming,” he said. Our technology is just that – the 10x change – the breakthrough. “Sometimes new innovations bring about a 10% rate of improvement, sometimes they result in 10 times a difference. The fattened grubs are then processed into poultry feed.īut it is the reactor technology behind the waste to feed process that is the real game changer, said Olivier. ![]() The company’s process is based on black solider fly (BSF) larvae eating waste sourced from grocery stores or school cafeterias.
