What issues does COASTAL Biogas address?
COASTAL Biogas turns problems into potential for the Baltic Sea region and environment – reducing eutrophication, creating renewable energy and high-quality bio-fertilisers from unwanted waste, making it easier to keep beaches clean and inviting for the region’s vital tourism industry and at the same time contribute to the transition to a circular bio-economy.
Seaweed is part of the algae family and a multi-facetted organism that has properties, which can be useful in many areas – among others medicine, energy and even as a targeted nutrient collector. Along with other algae it is the main organic component of beach wrack. By removing the seaweed from the beach, the nutrients do not re-enter the Baltic Sea and can help prevent eutrophication. There are many different species of seaweed and they are adapted to different regions.
In COASTAL Biogas one of the aims is to find effective beach-cleaning techniques and pre-treatment possibilities for using cast seaweed in biogas plants for producing electricity, heat and fuel. The digestate from the biogas plants can then be used as organic fertiliser and substitute imported synthetic mineral fertiliser.
