Mussel waste utilisation

This good practice shows how waste from mussel farming can be transformed into valuable resources through circular economy principles. By biologically fermenting undersized mussels to produce methane for renewable energy and repurposing shells as fertiliser or animal feed, the Cultimer-led project turns a significant by-product into economic and environmental value. 

The use of a mobile, on-site processing unit allows mussel farms to integrate the technology into existing operations, reducing waste, lowering environmental impacts, and easing financial pressure while promoting sustainable aquaculture along the Brittany coast.
