nextProtein· Paris, Île-de-France, France
The world’s population is estimated to reach more than nine billion by 2050. Global food production will have to increase by 70 per cent to feed everyone. Meanwhile one third of all food produced is wasted.At nextProtein we’re driven by a personal desire to address land and resource scarcity and feed a rising population sustainably. nextProtein can produce the equivalent amount of protein from 100sqm as 100ha of soya field.Founded by couple Syrine Chaalala and Mohamed Gastli, we produce insect-based protein for animal feedstocks with a negligible carbon footprint, at a lower cost and with the equivalent nutritional value of traditional protein production. We do this by taking otherwise unconsumed food on which to raise the insects, returning protein to the food cycle.nextProtein has years of experience in breeding Black Soldier Fly, which was selected specially for its beneficial, high-yield quality. Fly larvae are raised, harvested and then processed into valuable components of animal feed: an insect based protein for aquaculture, livestock and pets, an extracted fat and a natural fertilizer for use in agriculture.Our process is EU-approved for aquaculture and pet food and is suitable for feedstocks for the poultry and pork industries. Based in France with production operations in Tunisia, nextProtein is also backed by a range of high-profile international investors and business angels who have recognised our potential to revolutionise the industry.
