Rethinking Aquaculture for a Circular Future
Aquaculture is one of the world’s fastest-growing food sectors - but it still relies heavily on water, feed, and energy, often at the expense of environmental sustainability. At the same time, seafood processing generates millions of tonnes of crustacean shell waste every year, most of which is discarded and ignored.
This waste stream holds immense untapped potential. Rich in chitin and other valuable substances, it is too often treated as an afterthought in global food systems. We believe it doesn’t have to be this way.
At Merall, we are rethinking what aquaculture can be, not just a source of protein, but a launchpad for sustainable materials.
Sustainability by Design
Aquaculture as a Strategic Resource
To secure a sustainable and scalable source of biomass, Merall has developed an advanced aquaculture farming system centered on marbled crayfish — a highly resilient species uniquely suited for circular aquaculture. This low-impact system yields two high-value outputs: healthy, premium crayfish protein and a consistent supply of high-purity substances from side streams.
By integrating protein production and biomaterial recovery in one model, Merall transforms shell waste biomass into a valuable resource, significantly reduces waste at the source, and shows how sustainable food systems and biobased material innovation can work in harmony.
