【Abstract】In recent years, China’s rural areas have witnessed rapid economic development, and the living and production wastes in rural areas have gradually increased. However, due to the limited economic development level, some villages are lack of facilities for collection, treatment, and disposal of these wastes. The recycling of living and production wastes in villages is an important way for environmental protection in the rural areas and for improving the efficiency of resource utilization. It is easy to find some practical and mature technologies to treat one kind of wastes in rural area, but there lacks overall consideration for the recycling of production and living wastes in villages. In this paper, we took a typical village (village A) in the mountainous area of Xingtai City, Hebei Province as an example, and constructed a recycling system of production and living wastes. Fruit planting and rural tourism are the leading industries in village A. The main wastes in village A are fruit tree pruning, household solid waste, sewage, and manure. The recycling system of the village was constructed with technologies and facilities such as composting of organic wastes, pyrolysis of fruit tree pruning, sewage treatment, and the collection and treatment of solid wastes. The energy recovery and fertilizer use were realized in the village, and the residential environment governance achieved a higher level. A combination of analytic hierarchy process (AHP) and fuzzy evaluation method was adopted to construct the index system to evaluate the technology system of the recycling of wastes from living and production. A total of 26 indexes were chosen in the index system, which contained technological, economic and social, and environmental indexes. The weight of each index was determined by the expert scoring method. Residents’ acceptance, cost for garbage collection, average steady running time of the treatment facilities, and qualification rate of surface water and soil showed higher weights in rural area of north China. The method was used to evaluate the recycling system of village A, and the result showed that the technology system of recycling of wastes from living and production in village A was level excellent. The evaluation method could fully reflect the characteristics of the recycling mode of living and production wastes in rural areas. The evaluation methods in this study would provide a methodology reference for assessing, selecting, integrating, and promoting the technology system of recycling of wastes from living and production in China. It is a new thought to commit an overall design of the recycling system of the village, according to the village type, location, and regional economic, and to modify it through scientific evaluation, which can greatly improve the quality of rural area development, governance, and environmental protection. We will conduct evaluation and research on different types of typical villages in the southern area and the plain area of northern China in the future, further improve the evaluation method, and provide guidance for the construction and operation of the recycling systems of living and production wastes in natural villages.
