　Yokohama City collects sludge generated during the process of treating sewage at two sludge recycling centers in the city. We have been working to make effective use of resources, such as effectively utilizing biogas and sludge incineration ash generated during the treatment process.
　In this project, along with the renewal of sludge incinerators and improved soil plants in Hokubu Sludge Treatment Plant, the treatment process was added to incineration to promote measures against global warming and further effective utilization of resources. ※In addition to maintaining 1, maintenance and operation will be performed, including the improved soil plant currently operated by the PFI project.
　In carrying out the project, it will be implemented in a PFI project that can utilize private technical capabilities and funds.
＊1 A facility that manufactures bio-derived fuels that replace fossil fuels using sludge generated during the sewage treatment process as raw materials. The conversion of the system from incineration to the production of fuel chemicals is expected to significantly reduce greenhouse gases generated during the sludge incineration process.
