Abstract: Based on literatures and case study of Hangzhou， the characteristics of domestic waste in China and corresponding comprehensive treatment technologies were discussed. It was shown that compared with developed countries， kitchen garbage constituted the majority of domestic waste in China， and the proportions of recyclable materials were relatively high. Thus， it was necessary to carry out garbage sorting and recycling. As more than 50% of domestic waste in China were kitchen garbage， the focus of domestic waste treatment should fall upon kitchen garbage. Up to now， the main treatment technologies regarding kitchen garbage included transformation into feed， fermentation to produce biogas， composting and anaerobic fermentation. But， these technologies need to be greatly improved for largescale application. Finally， suggestions were proposed based on the situation of Hangzhou， such as advancing garbage sorting and recycling， developing more feasible waste treatment technologies and making proper policies to promote the comprehensive utilization of domestic waste.
