Abstract

After all principal steps in the MCL energy farming process have been demonstrated in previous contracts, this program aims to have the whole cycle running: algae production, harvesting, fermentation to biogas, and mineral nutrient recycling into the algae ponds (as fermentation residue (sludge)). Two pilot ponds (total area of 160 m**2) have been installed and operated which provided information on: pond regime, harvesting procedure and species control. The anaerobic digestability of micro and macro algae was tested at laboratory scale, the recycling of unoxidized fermentation sludge directly into the algae ponds was successfully tested over a period of 4 months. Finally, the productivities of 3 different algal strains, candidates for energy farming by MCL, were tested and compared. Tetraselmis showed the highest productivity yielding 65 tons/ha/yr, followed by Oscillatoria with about 88% of this, and Ulva with 68%. It seems, however, that with the last species the optimal yield has not yet been reached.
