Can a bug fix help food waste?
Food waste from homes, grocery stores, restaurants, and dining services – over 1 billion tons annually – ends up in landfills. Some is composted or used in other ways, but much ends in waste with China, India, and the US generating the most. Once in a landfill, wasted food emits carbon into the atmosphere, especially in the form of methane. Diverting food to feed those in need is one path; when past edible status, composting is another.

From the Eiffel Tower, the view includes cafés, restaurants, bakeries, and boutique grocery stores. A gourmet nation, France banned grocery store food waste, requiring by law in 2016 that stores donate edible food. Norway pledged to reduce food waste by working with groceries to discount or donate before “sell by” dates; Denmark followed suit. Japan, with little space for landfills – the fate of much wasted food – created a national food bank, supported by a new law requiring food recycling, and included lessons on food waste in the national educational system. In the US, California, Connecticut, Massachusetts, New York, Rhode Island, and Vermont developed no-landfill policies, introducing waste management systems and composting services.

But more is needed. Enter the black soldier fly larvae (BSFL). These critters have a hearty appetite and an impressive digestive track that can transform food waste into material for animal feed, prebiotics, cosmetics, and soil-amendment fertilizer, biogas, and even biohydrogen now in development- all from their own waste, termed “frass.” (Interested in that term? “Frass” derives from German “Fressen” meaning to eat with a certain style resembling gusto.)

In the US, several projects tested the little soldier fly as part of the Fertilizer Production and Expansion Program (FPEP). Oregon’s Chapul Farms introduced the approach in their closed-loop agriculture program in partnership with Tainable: Regenerative Agricultural Laboratory. Mississippi State University’s Department of Plant and Soil Sciences assessed the approach, noting that BSFL mate and multiply quickly.

Ethicists raise issues regarding insect farming, an industry worth $1.18 billion in 2023. Mealworms and crickets are commonly raised to be sold directly as food or for producing animal feed; pulverized insect powder is used in breads and protein bars. But BSFL may be different because the insects are not consumed, but rather fed. It is their by-product, frass, that is used; not them. Still, there is production on an industrial scale. What is your view?

A bug fix might be part of the future of food, sustainability, energy, and farm regeneration. Black Soldier Fly’s favorite snack? Rice with coconut milk or a serving of Mango with Coconut Cream Sticky Rice, a specialty during the month of March in Thailand – a dish so delicious there are rarely left-overs, but when there are…
