Sustainable development of sludge disposal and resource utilization in Chinese farms

Abstract

At present, China’s sludge disposal is in the primary stage of development, and there are still having some significant defects in the terminal treatment of the sludge disposal link. The treatment methods are often extensive, such as incineration and landfill, and the application level of sludge recycling is very low. At the same time, China has large number of farms, which will produce a lot of animal waste every day. Traditional disposal methods such as burning and landfill are difficult to make the waste resource available. There is no denying the fact that there is immeasurable agricultural and economic value in the sludge and excrement, but it is not used properly at present. This paper will analyze the current situation, trend and prospect of sludge treatment, and further explore the new ways of urban sludge disposal and resource utilization in China, which may broaden the possibility of sustainable development of China.
