Subcritical water treatment is considered a “green” way to extract useful compounds from waste biomass.

In the case of sustainable energy, the company has developed its own integrated system which it calls the Subcritical Water Organic Waste Power Generation System, or ISOP system, which ultimately produces various energy products. green from waste.

With NYK’s investment, the size of which was not disclosed, the companies will conduct joint studies on converting organic waste generated on ships, such as garbage and sludge, into fuel using the ISOP system. .
