NYK invested in Sustainable Energy Co. Ltd., an energy-supply company that uses unused resources like flammable garbage generated in cities.

Sustainable Energy has created its own integrated subcritical-water organic-waste power-generation system, or ISOP system, which uses subcritical-water-treating technology to break down organic material and produce green energy, such as biofuels.

With this investment, NYK will commence collaborative research on recycling organic waste, such as garbage and sludge, into fuel using the ISOP system.

NYK will promote the commercialisation of this new technology by investing in Sustainable Energy, as well as collaboratively exploring the generation of energy raw materials from organic waste such as garbage and sludge using an ISOP system fitted on a vessel.

In the future, NYK, in collaboration with Sustainable Energy, will encourage ship decarbonisation through research and development, such as using the generated energy raw materials as fuel for vessels.

The ISOP system is a revolutionary system comprised of equipment that decomposes organic substances such as combustible garbage into low-molecular-weight compounds in a closed space, utilising subcritical-water-treating technology to generate energy from raw materials in powdery and dry form.

The energy raw materials created can be reused as green energy products such as bio-coal, biogas (e.g., methane and hydrogen), bio-coke, etc. Unlike existing incinerators, the ISOP system is environmentally friendly and does not release dangerous substances such as dioxins.

The ISOP system does not require waste segregation and is effective for flammable waste, vinyl and plastic, styrene foam, clothing, food waste, organic sludge, animal manure and sludge, wood chips, and almost all other organic substances.

The ISOP system can be easily made larger or smaller, and even movable vehicle-mounted models are being developed. The system is expected to be used in a variety of situations, such as urban-area office buildings, municipalities, and disaster areas, among others.
