HANGZHOU (Enmaeya News) — October 1, 2025

Researchers in China have created a system that uses fly larvae to process rural food waste. The method turns discarded food into protein-rich animal feed while cutting environmental impact.

The study, published in Frontiers of Environmental Science & Engineering, introduces a new waste-processing system that allows black soldier fly larvae to break down food more efficiently. Known as a “continuous self-separation reactor,” the system uses microorganisms to speed decomposition, keeps heat in, and even collects liquid waste automatically..

Food waste is a major challenge in rural areas. Sorting is often limited and recycling systems are weak. By combining insect behavior with engineering, the reactor offers a sustainable, low-cost alternative to traditional waste treatment.

In trials, the reactor reduced food waste by nearly 57% within five weeks. The larvae that emerged were rich in protein and fat, making them a valuable feed source for livestock and aquaculture.

Experts say the innovation highlights the growing interest in insect-based technologies to handle food waste. It could also cut landfill use and create sustainable food supplies.

The research team believes the reactor could be scaled up to serve whole villages, providing a green model for rural waste management.
