Mitsubishi Municipal Solid Waste (MSW) Gasification and Ash Melting System [ Waste to Energy System ] [ ENVIRONMENT ]

  • Linkedin

With heightened concerns for global warming, environmentally friendly ways to incinerate waste have become of critical.

Kushiro MSW Gasification & Ash Melting Plant

Waste treatment capacity 240 t/day (120 t/day × 2 units)
Electric generating capacity 4.6 MW
Waste type Municipal Solid Waste
Dioxins at the stack 0.00011 to 0.0055 ng-TEQ/Nm3
Annual operation more than 280 days


  • 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.
