The Qianzishan organic solid waste treatment project stands as the largest of its kind in central China – and the largest food waste treatment project under construction in the country to adopt dry anaerobic digestion technology.

Guided by the principle of waste-to-resource transformation, the project employs a range of innovative processes, including:

Solid residue energy recovery

Digestate composting

Combined heat and power generation from biogas

Waste heat utilization.

These integrated technologies turn discarded kitchen and food waste into valuable resources, maximizing the efficiency of material and energy recovery.

Not only does the project represent a leading standard in China’s waste treatment sector, but it also serves as a benchmark and reference model for similar initiatives nationwide.
