In this project, the effectivity of extracting alga from the sea and using
it as a fertilizer or for the production of biogas was tested. When the
alga is extracted from the water in shallow bays, large quantities of nitrogen
and phosphorus, that have been absorbed by the alga, are also extracted
at the same time. In this way, fewer nutrients are left in the bays and
burden the system.
|In one project, a harvester is being tested to
gather up the algae on the water surface and squeeze out the water.The
mass of algae is then transported away to be used as fertilizer,
in the production of paper and biogas.
