Mitsubishi Municipal Solid Waste (MSW) Gasification and Ash Melting System
Mitsubishi Municipal Solid Waste (MSW) Gasification and Ash Melting System
With heightened concerns for global warming, environmentally friendly ways to incinerate waste have become of critical.
MHI Group has a proven track record of delivering more than 200 advanced, reliable waste-to-energy (WtE) plants since 1964. In 1998, we developed the Mitsubishi Municipal Solid Waste (MSW) Gasification & Ash Melting System, an advanced WtE system to combat the issue of waste and environment and help build a fully recycling society for future generations. The first commercial plant was built in Kushiro city, Japan in 2006, near the Kushiro Shitsugen National Park, Japan’s largest marsh designated as a Ramsar site. The plant has been operating successfully as the advanced and most environmentally friendly WtE system.

Advantages
- The process of gasification and ash melting of the system allows high recyclability compared to conventional incineration systems.
- The system achieves an extremely high level of control of dioxins emission, not only in the gas emitted but also in the construction material by-products produced from melted ash.
- Metals (aluminum, iron, and steel) contained in the waste can be recovered and recycled with rather high sales value compared to metals from conventional incineration.
- Dioxin-free melted ash or molten slag can be used as construction materials such as asphalt for paving roads.
