Circular recovery of methanization digestates through microalgae production and the rearing of edible decomposer insect larvae

Description

The project aims to develop a new way to recover liquid digestates from methanization by producing microalgae as a solution to reduce the cost of the feeding regime used to rear black soldier fly larvae, as well as the cost to dispose of the waters.  

The proposed approach is to have a microalgae culture use the liquid digestates from methanization and then set out a feeding regime of microalgae and solid digestates.

What separates this proposal from others is the fact that it interweaves a circular innovation project in an emerging circular economy loop. The innovation lies in the development of a less costly feeding regime to rear black soldier fly larvae whose main component is the production of microalgae from liquid digestate from methanization (a waste).

This new approach to liquid digestate management and the production of edible and decomposer insects fits seamlessly into the circular economies of several cities and regions across Québec and around the world.
