AbstractWith the increasing of sludge emissions and people's increasing demand for better dwelling environment, resource utilization of sludge receives much concern in recent years. Currently, the co-processing of sludge in cement kiln has been considered as a sustainable way to dispose sludge in Japan as well as Europe and the United States. Huaxin has begun the co-processing of sludge in cement kiln since 2008. So far, 65000 tons of sludge has been successfully disposed. This paper focus on 3 ways of co-processing sludge in cement kiln through certain project examples.
