French insect producer Agronutris selected Bühler Group as the process solution provider for its first commercial-scale black soldier fly plant in Rethel, France. The plant is scheduled to go into operation in 2023.

The approximately 172,000 ft2 (16,000 m2) insect plant, when operating at full capacity, will process up to 70,000 tons of organic residues and produce protein for the aquaculture and pet-food markets. Bühler will provide feedstock preparation to supply feed to the larvae; an automated larvae growth system with climate control; and a frass-handling system. Bühler also will deliver a processing line to convert the grown larvae into protein meal and lipids.

In addition, Bühler will be responsible for project execution, which encompasses engineering, procurement, manufacturing, supply, installation and commissioning.
