As the agricultural industrial waste resources and garbage, city sludge found economic and environmental protection utilization, by waste, waste, scientific and rational use of waste resources, is a major responsibility of chemical fertilizer enterprises, is a pressing matter of the moment. This is the China Chemical News reporter from 11 to 10 in Hubei,, held in Jingzhou, the 2015 national waste resources in the application of fertilizers in the application of the high-end forum to understand the information.
According to Shao Jianhua, director of the research and development cooperation alliance of the new fertilizer industry, the application of waste resources in fertilizer is an effective way to develop circular economy. Using crop straw as raw materials in food and agricultural and sideline products produces more than half of the waste, mostly as "three wastes" after treatment of landfill. In recent years, a serious decline in soil organic matter in China, the trace elements in the serious lack of the central idea of the "fertile soil engineering construction, provides a broad market for trace elements in organic fertilizer and fertilizer, and the fertilizer can be obtained from the local agricultural industrial waste resources.
At present, agricultural non-point source pollution has become a serious challenge to the sustainable development of agriculture in China. "The reduction in soil fertility is the one hand, the environmental loss is even greater. The loss of fertilizer and straw, livestock and poultry manure, Chinese medicine and other waste, is making another ecological disaster." Professor Liu Dehui, School of resources and Environmental Sciences, Nanjing Agricultural University.
Professor of life science and technology, Dalian University of Technology, Professor Xu Yongping said that the number and quality of aquaculture waste can basically meet the needs of the growing industry on the organic fertilizer, composting can be harmless treatment and resource utilization of livestock industry. Study on the prospect of composting industry wide, tremendous business opportunities, including the development of functional agents is the core and key.
Zhou Jianbin, Professor of Nanjing Forestry University, said: "biomass (straw) gasification power generation, carbon, fat, heat technology, is a good way to use biomass, such as straw and other biomass efficient, pollution-free and resource utilization, but also to solve air pollution, soil pollution, water pollution and food safety issues. The implementation and promotion of biomass energy production technology will make the sky more blue, the water is more clear, the food is safer."
In order to speed up the promotion of Jiangsu province agriculture fertilizer waste, the quality of cultivated land protection station promotion researcher Huang Bin proposal: to ensure the quality of products and waste fertilizer use effect; establish a waste fertilizer production, scientific supervision system as soon as possible; the government to increase investment and promotion efforts, improve user awareness and application of waste fertilizer through farmland experiment and enthusiasm; demonstration, suitable price, fast delivery, user trust as soon as possible and the use of waste fertilizer.
