Overview of Incineration Plant
Last Updated December 29, 2021
About Kanazawa Plant
This is a state-of-the-art factory in Yokohama, which started operation in 2001, safely and sanitizes approximately 800 tons of waste (when two furnaces are operated) in a safe and sanitary manner.
The Kanazawa Plant incinerates household waste from households in Kanazawa Ward, Isogo Ward, Sakae Ward and Konan Ward, and a portion of household waste in other wards, as well as business-related general waste from offices and factories.
Waste heat generated by incineration of garbage is collected by a boiler, effectively used in heated pools, and power is generated using a steam turbine. The generated electricity is used in the factory and supplied to nearby Nambu Sludge Treatment Plant and Renetsu Kanazawa. Additionally, the surplus is sold to power companies.
