Sanitary landfill, Burning, Compost are the main method to dispose gabage in China.If urben refuse is put into the cement kiln, processing it, producing cement, it will benefit all. This mature method has no influence on neither the cement production nor the quality of cement products,however the indexes of all emissions in the manufacturing meet the national standards. Statistics show the heat generated by every ton of waste is equal to that of 183kg standard coals; the cinders are mixed in cement during the treatment process, thus 107kilograms substitute raw materials can be generated by every ton of waste, and 6 to 7 percent are added. Moreever, it reduces carbon dioxide emission 8000 tons for every 10,000 tons waste. This paper concludes: the utilization of cement kiln to incinerate domestic waste has obvious advantages in environmental protection and total investment does not cost much. The municipal engineering construction has the priority to use the products from domestic treatment cement factories, and domestic waste incineration cement factories should be under self-management. Also supportive policies as well as the readjustment of waste treatment management and interest pattern can promote the development of treating urban domestic waste by cement production.
