With the level of economic development, people's consumption, production methods are becoming more diverse, MSW has produced the increase. In many urban waste disposal methods, MSW composting is a good approach. Garbage disposal method is the use of microbial activity will refuse the perishable organic matter decomposition into rich in organic matter and nitrogen, phosphorus, potassium and other nutrients, organic fertilizer. High quality compost is a good organic fertilizer, is a good soil conditioner and the regulator, on the physical and chemical properties of soil improvement and the improvement of crop quality with positive implications. the application of agricultural production has bright prospects. Therefore, Application composting method to deal with the organic-rich MSW composting is the production of MSW resources processing a important direction is that people are a hot research. In this paper, mainly on the MSW composting technology and the key to composting of the major components, Nutrient and its application in agricultural production on the environment and the positive impact of the negative effect of the relevant exposition. Finally, the above problems and corresponding countermeasures, such as changes in the traditional composting method, and other waste disposal methods life combined; of the heavy metals in soil control; Composting of deep processing, made a series of high-efficiency organic-inorganic compound fertilizers, and so on. Although the current theory and the composting technology is not perfect, but compost is very good market prospects, composting deserves to be and to popularize.
