Introduction of a New DBO Incineration Facility - A Complete Overview of Refuse Disposal, Energy Recovery, and Related Technologies in 2007 (November 2007)

In 2007, Japan was in a hurry to introduce high-performance incinerators against the backdrop of tight landfill space and the dioxin problem. The focus was on the DBO method, in which the private sector is responsible for everything from design to operation, and local governments sought to optimize costs while ensuring stable treatment and compliance with environmental standards. The new facility was designed with an emphasis on waste power generation rather than mere volume reduction, combining a stoker furnace and fluidized bed furnace with a high-temperature, high-pressure boiler to improve power generation efficiency, and a condensate extraction turbine to provide heat supply. The waste gas treatment is a multi-stage system that removes acid gas, mercury, and dioxin, and is constantly monitored by CEMS. The ash is recycled by magnetic separation and melting process. In addition, AI control and condition-based maintenance were introduced to achieve efficient operation and
shortened downtime. The DBO system was a symbolic step toward a recycling-oriented society that combined technology and contractual schemes to compensate for the financial difficulties of local governments.
