Anaerobic digestion of fish processing by‐products

Anaerobic digestion can be used to treat many organic waste streams. However, fish wastes pose a particular technological problem, as they release high levels of ammonia when digested, which then inhibits the digestion process. Having overcome these technical problems, it is important that there is a long term, financially viable outlet for the products of the digestion process. The organic sector places high demands on the production of certified inputs, but, if these can be met, this sector represents a potentially high value market for the products of a digestion process.
