The unit price of kitchen waste treatment subsidy is 280 CNY/ton. The BOT mode is adopted for operation and the service period is 26 years. The service scope of the project includes Dangtu County, Haushahn District, Yushan District, Bowang District, municipal economic development zone and Cihu high tech Zone. 

The main treatment process of kitchen waste is “crushing + extrusion dehydration”, and the overall technical scheme is “solid-liquid separation + deodorization system (dining kitchen coordination) + solid-phase combustion treatment (incineration coordination)”.
