Innovative uses for mussel waste products

The ‘Musselfeed’ company in Sweden uses discarded mussel products to develop feed, food, and flavouring products.

In the mussel industry, some blue mussels (Mytilus edulis) don’t make it to the consumer market because they are too small or are considered ‘ugly’ (lime on the shell, discolouring, etc.). These mussels form the basis of the Musselfeed product line. The lowest-grade material is used as a nutrient-rich animal feed, for example as feed for hens to improve egg quality. The mid-grade material is used to provide nutrients to foods, for example in burgers, bars and other products. The higher-grade material is used as a flavouring agent, rich in umami, for seasoning. The company uses an innovative method where the meat is separated from the shell so that it can be gently dried, preserving the nutrients and providing a healthier product.

Results

  • By replacing other protein sources such as red meat with mussel powder, the end products can have 30-160 times lower climate impact.
  • The products can reduce the need for unsustainable feed sources such as fish and soymeal.
  • Mussels improve coastal water quality through uptake of nitrogen and phosphorous. Harvesting mussels can recycle nutrients back to land.
