Biogas to be produced from poisonous algae?
Swedish researchers are now gathering poisonous alga with the help of oil sump pumps. The aim is to use this system to save sensitive shores and at the same time use the alga soup in the production of biogas. The current project is led by Fredrik Gröndahl, associate professor at KTH in Stockholm.
The Baltic Sea is one of the most polluted in the world. In the last 50 years it has suffered from over-fertilisation and during this process the poisonous algal blooms have become more common.
The new method is currently tested on alga in the St Anna archipelago outside Norrköping.
