Overview of Maishima Incineration Plant
Osaka City built a new Maishima Incineration Plant for the express purpose of dealing appropriately with waste treatment and environmental conservation. The Maishima Incineration Plant is equipped with an incinerator and a crushing plant for bulky waste and not only has the latest pollution prevention facilities and uses the heat that is generated to the maximum, in order to preserve the environment the famous Austrian environmental conservation architect, Friedensreich Hundertwasser was engaged to design the exterior, making this plant a popular mecca for study tours.
- Incineration capacity
- 900 tons per day
(450 tons per furnace x 2 furnaces)
- Crushing capacity
- 170 tons per day
(iron and aluminum are recycled)
- Exhaust gas treatment
- bug filter, moist cleaning equipment, catalytic equipment for removing NOx, etc.
- Coping with dioxins
- The plant keeps exhaust gas concentration below 0.1 nanograms by computer controlled high-temperature operation + use of bug filter + catalytic NOx removal. Dioxins in escaping ash are decomposed with superheated dechlorination equipment
- Chimney height
- Water conservation
- Collects rainwater from the roof. Recycles wastewater.
