Features of Ash Washing System
Quality/safety of the recycled product (cement)
The trace amounts of dioxins contained in soot are safely broken down during high-temperature incineration within the rotary kiln at 1,450°C.
The percentage of incineration residue used is kept below several percent of the overall raw materials. This means there is no negative impact on cement quality, and heavy metal content can be controlled within a completely safe range.
Economic viability
 |
Recycling large quantities of incineration residue from municipal garbage as raw material for the large volumes of cement produced makes it possible to reduce the costs of building final disposal sites. Furthermore, it eliminates the costs associated with having to stabilize heavy metals in the landfills at final disposal sites.
Contributions to the global environment
・ |
Helps build a recycling-based society by not only extending the service life of final disposal sites, but also through reducing the amount of natural resources used, such as clay and limestone. |
・ |
Cement is not contaminated with dioxins, as they are completely broken down within the rotary kiln where the material is fired to 1,450°C. |
