Japanese shipping company NYK has invested in compatriot Sustainable Energy to study converting organic waste on vessels into fuel. Sustainable Energy specializes in biomass power generation from waste collection. Sustainable Energy has developed an integrated subcritical-water organic-waste power-generation system (ISOP), which decomposes organic substances using subcritical-water-treating technology and ultimately produces green energy products such as biofuels. Through this investment, NYK will begin joint studies on converting organic waste such as garbage and sludge generated on vessels into fuel by utilizing the ISOP system. The ISOP system is an environmentally friendly system that does not generate harmful substances such as dioxins.
