Projektziel und Kurzbeschreibung / Project aim and short description

The main objective of the COASTAL Biogas project is to provide solutions based on anaerobic digestion of cast seaweed to coastal regions to tackle eutrophication, contribute to the transition to a circular bio-economy and improve prosperity.

Eutrophication has both ecological and social consequences and is one of the major environmental problems of the Baltic Sea. At the same time there is a need for a transition from a fossil based to a sustainable bio-based society. The project focuses on the removal of nutrients from the Baltic Sea by collecting cast seaweed to counteract eutrophication. The seaweed will be used as a co-substrate for anaerobic digestion. Furthermore, the digestate can replace artificial fertilisers and hence, contributes to closing nutrient (N & P) cycles. The produced biogas can be utilised for electricity, heat and bio-fuel production.

Cross border technology guidance and transfer in seaweed co-digestion will be supported. A decision support tool and training kit for biogas plant operators, municipalities, local authorities as well as beach cleaning companies, farmers, waste management companies, etc. will be developed. Moreover, the procedure of anaerobic digestion of seaweed and digestate utilisation in the South Baltic area will be improved.
