In order to strengthen food waste management, ensure food safety, promote resources recycling, maintain urban and rural beauty and environmental health, Changzhou plans to carry out construction of food waste comprehensive disposal project according to relevant policy in Jiangsu.

Design collection and transportation scale: operation scale of the phase 1 is 200 t/d for food waste and 40t/d for waste oil. The collection and transportation scale meets needs of actual work and pilot cities. Annual capacity of food waste treatment facilities shall not be less than 73000 tons and the daily capacity shall not be less than 200 tons; annual capacity of waste oil shall not be less than 14600 tons and the daily capacity shall not be less than 40 tons.

Process adopted in this project is "pretreatment + anaerobic digestion". The process mainly includes: food waste pretreatment, anaerobic digestion, biogas purification and utilization, biodiesel production, aerobic composting system, etc. After sorting and pulping, organic matter enters anaerobic digestion reactor, and biogas is generated through biological anaerobic process. After a certain residence time, the remaining anaerobic digestion liquid is discharged from the system. Biogas, biogas slurry and bio

About 10.4 tons of crude oil can be produced by pretreatment of food waste and waste edible oil; 8.84 tons of biodiesel can be produced by biodiesel production system; 14231 m3 of biogas can be produced every day after anaerobic digestion, which can generate 2111 kwh of electricity every day except for steam boiler.
