Abstract: The continuous increasing of municipal refuse has led to the difficulty in their complete treatment solely by traditional means. By using ecological engineering technologies to develop municipal refuse treatment and utilization ecological industry so as to internalize treatment and environmental protection into utilization and industrial production is an appropriate way of solving this problem. The results of a pilot study in Guanghan City showed that the connecting of hardware (innovation of techniques and equipment,etc.),software (revision of laws and policies, reform of institutions, etc.) and mind ware (behavioural inducement and education), the leading of the government, the support of scientific technology, the involvement of the enterprises, and the participation of the local residents are the key factors for the minimization, innocuity and resourcification of municipal refuse,and for the industrialization and systemization of its disposal. By taking those measures, social, economic and ecological benefits could all be obtained. The principles, the practical measures and the designing for ecological engineering of municipal refuse treatment and utilization have been discussed.
