Buzz to biowaste – these flies help turn food waste into compost
With global food waste on the rise, innovative solutions are critical—enter the black soldier fly. Purdue University’s Laura Ingwell researched how this insect rapidly transforms organic waste into compost and protein-rich livestock feed. Unlike traditional composting, which is slow and limited, black soldier fly larvae consume vast amounts of waste—including meat, dairy, and even pesticide-laced materials—quickly and safely, reducing harmful bacteria and chemicals. Ingwell’s work focuses on making this process viable for small and urban farms, especially in colder regions where fly survival is a challenge. Her team is developing insulated compost bins and studying food safety implications. Internationally, Ingwell helped farmers in Timor-Leste use black soldier flies to create a sustainable cycle: feeding flies with waste, harvesting larvae to feed fish, and improving local food security. Through education and research, black soldier flies are emerging as a powerful tool in reducing waste and supporting circular agriculture systems worldwide. Learn more about this innovative solution.
