Food waste eaten by fly larvae is making compost and then stock feed

Black Soldier Fly maggots – the key to solving food waste. CSIRO

It is well known that the life cycle of insects is from eggs to larvae to pupae to adults. It is the Black Soldier Fly larvae (maggots) that are of special interest as they consume food scraps. They are eating machines, turning scraps into compost at a very fast rate.

The start-up company Gottera, based in Canberra, Australia is processing five tonnes of food waste a day with these larvae. Goterra not only manages waste to compost it also sells the mature larvae, a rich source of protein, as stock feed. So far the maggots can be used by chicken and pork producers, zoos, fish bait suppliers and as an ingredient in aquaculture pellets but have much more potential.

Goterra is all about driving Australia towards a circular economy for food production. And breeding insects is critical to their vision. The original breeding research was done in partnership with the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Canberra. CSIRO’s research helped Gottera breed the flies for effective results.
