Aquaculture

Maritime Sector

Land based aqua culture is growing world wide. We are taking care og  residual fish sludge, and turning it into a valuable biofertilizer.

Fish farming in land based Recirculating Aquaculture Systems (RAS) is growing both for salmon farming and other fish species.

• The fish farms faces some environmental challenges among those are:

• 1000 tons of feed creates some 3000m3 of fish waste (sludge residues). New regulations forces the industry to take care of the sludge. A typical smolt farm creates some 6000m3 of sludge yearly.

• Fish mortalities create another waste problem

• Global shrimp farming amounts to some 5M ton / year. In addition wild caught shrimp is about 4M ton per year

• Much of the shrimp peel is to day a waste product
