Project Mila’s team of volunteers collect organic waste from households, markets and restaurants in Mombasa and feed it to voracious larvae

A group of young Kenyans are working on an unusual solution to the problems of food waste and fish feed produced unsustainably from wild-caught fish stocks: maggots.

The larvae of the black soldier fly are now devouring unwanted food in projects around the world. Their excrement, known as frass, can be used as a fertiliser for land-based crops, and their protein-rich bodies, harvested before they turn into flies, can be fed to livestock.
