We have implemented the method of "Secondary Sorting and Four Classifications" in Taizhou City, by which organic perishable waste and other waste are put in separate bags to achieve precise front-end household separation. The waste is reasonably laid out at drop-off points, and cleaners come to collect the waste regularly and carry out secondary sorting so as to standardize the mid-end collection and transportation. In addition, according to the different characteristics of waste such as recyclable, organic and perishable, toxic and harmful waste,etc., specialized treatment is carried out in different categories to achieve ecological end disposal.

This 200t/d project uses anaerobic process to carry out full fermentation of organic matter from kitchen waste after oil extraction, while the biogas is purified and used for power generation. The biogas fluid is separated from the digestate and before entering the treatment system. All devices are under negative pressure to effectively contain odor.
