Marine environmental technology cleans the seas

The system to culture and harvest ascidians from the sea is a novel clean-tech concept where the process gives several environmental and economical benefits:

  1. When the biomass is digested it produces a renewable energy source in the form of biogas
  2. Harvest of the marine biomass produces a net uptake of nutrients from the sea with a low cost per removed kilogram of nitrogen
  3. The rest product, digestate, is a valuable nitrogen fertilizer for agriculture
