Mitsubishi Heavy Industries Environmental & Chemical Engineering Co. has completed the construction of the Nanbu Relay Centre in Minamishimabara City, Nagasaki Prefecture, for the Ken’ou-Kennan Clean Authority. The project strengthens waste transfer infrastructure across the region.

The new facility enables efficient handling of combustible waste, with a capacity to compress and process approximately 43 tonnes per day before transportation to the Ken’ou-Kennan Clean Centre in Isahaya City. It forms part of a broader system including the existing Tobu and Seibu relay centres.

The project, awarded in 2024, involves both construction and long-term operations under a Design-Build-Operate model. MHIEC, in partnership with Jukan Operation Co., has secured a 20-year contract to manage all three relay centres. The total contract value stands at approximately ¥11.375 billion.

Relay centres play a key role in waste logistics by compressing collected waste and transferring it to larger vehicles for efficient transport to treatment or disposal facilities.

The development reflects MHIEC’s continued focus on integrated waste management solutions, combining infrastructure development with long-term operational capabilities, while supporting efficient and sustainable urban waste systems.
