Realizing Towns that Can be Lived in Comfortably:
Welcome to Hiroshima Chuo Ecopark
- A facility with excellent resourcecirculation/
energy use - A facility serving as a base for environmental study
- A facility combining nature with the local community
- A facility serving as a base for disaster response/prevention
Hiroshima Chuo Ecopark is a facility that treats waste from Higashi Hiroshima, Takehara, and Osakikamijima.
We strive to be a base for an advanced material-cycle society by building a zero reclamation system.
A facility with excellent resource circulation/energy use
We use energy generated in the melting process effectively for power generation, selling surplus electric power and utilizing it efficiently.
Also, the waste is converted into recyclable materials, resulting in a zero reclamation system.
Melting process flow
- Thermal energy use
- We use thermal energy generated by waste treatment to generate power. This leads to a reduction of the fossil fuels needed for thermal power generation and a decreased burden on the environment.
- Zero reclamation
- We achieve a zero reclamation by melting and reusing bottom ash and incombustible residue generated by our stoker incineration method.
- Reuse of molten materials (slag/metals)
- Melting waste at a high temperature decomposes dioxins and removes heavy metals, so all materials are reused as harmless, safe molten slag in a sand form and metal.
- Smelter recovery (valuable metals)
- Smelter recovery is a technology for extracting and recovering lead, zinc, copper, and other valuable metals from molten fly ash discharged from the waste treatment facilities of nonferrous metal manufacturers' smelters.
