Nippon Yusen Kaisha (NYK) is looking to convert the waste that ships produce into Energy. Japan’s second-largest shipping line, by dwt, has invested in Sustainable Energy, which operates an energy supply company making use of resources that are not used, such as city waste that can be flammable.
Sustainable Energy has developed its own integrated subcritical-water organic-waste power-generation system, or ISOP system, which decomposes organic substances using subcritical-water-treating technology and ultimately produces green energy products such as biofuels. With this venture, NYK and Sustainable Energy will start joint studies to convert organic waste like the sludge and garbage generated on vessels into fuel through ISOP. ISOP system.

The ISOP system decomposes organic substances such as flammable waste into low-molecular-weight compounds using subcritical-water-treating technology in a closed space to generate energy raw materials.

The ISOP system doesn’t require the segregation of waste. It is suitable for the disposal of flammable waste, plastic and vinyl foam, clothing, styrene organic sludge, food waste, the manure of animals and their sludge, wood chips and all other organic materials. The ISOP system is easily altered to make it smaller or bigger and even mobile vehicle-mounted models are being designed.

Compatriot shipping firm Mitsui OSK Lines (MOL) has been developing similar technologies. Microplastics that have been retrieved from the ocean using a specific device MOL developed and then installed onto one of the woodchip carriers are being transformed into energy-producing products similar to wood pellets. The microplastic collection device of MOL operates in conjunction with the ballasting process for water.
