Advances in Recycling and Utilization of Agricultural Wastes in China: Based on Environmental Risk, Crucial Pathways, Influencing Factors, Policy Mechanism.

With the development of agriculture in China, the productions of agricultural wastes increase rapidly. The occurrence of agricultural wastes was unique in the different areas. The agricultural straw and livestock excrement are considered to be potential resources. Improper disposition of agricultural wastes not only result in environmental pollution, but also waste a lot of valuable biomass resources. The recycling and utilization of agricultural wastes are considered to be the important step in environmental protection, energy structure and agricultural development. However, the problem in China's current agricultural waste recycling impeded the achievement of scale ecological functions. The objectives of this study were to illuminate the potential environmental risk, recycling and utilization pathway, influencing factors and policy suggestions in the recycling and utilization progress of agricultural wastes. The survey provided the development mode of industrialization and scale of agricultural waste recycling. The recycling and utilization pathway of agricultural wastes were also analyzed. The crucial suggestions were proposed, such as cultivating new industry, building economy incentive standard, improving laws and regulations, and creating rural market strengthening medium and long-term plans of agricultural waste recycling. The resource consumption, ecological crisis and other issues caused by agricultural wastes were evaluated. It will provide more comprehensive fundamental information for the recycling and utilization of agricultural wastes during the modernization and urbanization of China. [ABSTRACT FROM AUTHOR]
