The feasibility of utilizing Wuhan’s domestic waste to refill the discarded Daye open iron mine is stated in the paper as follows: (1) the situation and existent of primary problems of municipal solid domestic waste (MSW) are analyzed; (2) the characteristics of the open iron mine and primary problems are investigated; (3) the feasibility of utilizing domestic waste to refill a more or less stable open mine and aspects of reconstruction of the landscape are presented in general; (4) the primary economic evaluations are performed. The results indicate that much money will be saved in the long term by cutting expenditure on Wuhan’s domestic waste disposal and by recultivating land for the mine. In addition, environment surrounding the mine and Wuhan city will be improved and much land for landfills will be saved. Keywords: waste disposal, discarded open mine reconstruction. 1 Introduction In China, municipal solid domestic waste (MSW) amounted to 150.0 million tons in 2002. In the past few years, MSW has been dumped in the cities’ surroundings, which has now resulted in more than 2/3 of the cities in China being besieged by MSW. The soil, water and atmosphere near the dumps of
