In order to thoroughly implement the spirit of the Fifth Plenary Session of the 19th CPC Central Committee, further improve the comprehensive utilization level of bulk solid waste, comprehensively improve the utilization efficiency of resources, promote the construction of ecological civilization, and promote high-quality development, the guiding opinions are formulated.
1、Current situation and situation
（1） The achievements of the 13th five year plan. Since the 18th National Congress of the Communist Party of China, China has incorporated the comprehensive utilization of resources into the overall layout of ecological civilization construction, continuously improved laws and regulations, strengthened scientific and technological support, and improved standards and norms, and promoted the development of comprehensive utilization of resources industry, and made positive progress in various work. In 2019, the comprehensive utilization rate of bulk solid waste will reach 55%, 5% higher than that in 2015; among them, the comprehensive utilization rate of coal gangue, fly ash, industrial by-product gypsum and straw will reach 70%, 78%, 70% and 86% respectively. During the 13th Five Year Plan period, a total of 13 billion tons of bulk solid waste were comprehensively utilized, which reduced the land occupation by more than 1 million mu, provided a large number of products for comprehensive utilization of resources, promoted the high-quality development of coal, chemical, electric power, steel, building materials and other industries, and achieved remarkable resources, environment and economic benefits, which played an important role in alleviating the shortage of some raw materials and improving the quality of ecological environment in China Use.
（2） The situation facing the 14th five year plan. During the period of the "14th five year plan", China will start a new journey of building a socialist modern country in an all-round way. The task of comprehensively improving the efficiency of resource utilization around the theme of promoting high-quality development is more urgent. Under the influence of resource endowment, energy structure, development stage and other factors, China's bulk solid waste will still face severe challenges of high production intensity, insufficient utilization and low added value of comprehensive utilization products in the future. At present, the accumulated storage of bulk solid waste is about 60 billion tons, and the annual new storage is nearly 3 billion tons. Among them, the utilization rate of red mud, phosphogypsum, steel slag and other solid wastes is still low, occupying a large amount of land resources, and there are great ecological and environmental security risks. We should thoroughly implement the law of the people's Republic of China on the prevention and control of environmental pollution by solid waste and other laws and regulations, vigorously promote the source reduction, resource utilization and harmless disposal of bulk solid waste, strengthen the whole chain governance, strive to solve outstanding contradictions and problems, and promote the new development of comprehensive utilization of resources industry.

15、 Q & A
16、 The national development and Reform Commission, together with nine departments, issued the guiding opinions on the comprehensive utilization of bulk solid wastes during the 14th Five Year Plan period (hereinafter referred to as the Guiding Opinions). Relevant responsible comrades of the national development and Reform Commission were interviewed and asked questions by reporters.
17、 Q: what is the background of the promulgation of the guiding opinions?
18、 A: Bulk solid waste (hereinafter referred to as "bulk solid waste") refers to a single type of solid waste with an annual output of more than 100 million tons, including seven categories of coal gangue, fly ash, tailings, industrial by-product gypsum, smelting slag, construction waste and crop straw, which is the key field of comprehensive utilization of resources. China has always attached great importance to the comprehensive utilization of resources. Since the 18th National Congress of the Communist Party of China, China has incorporated the comprehensive utilization of resources into the overall layout of ecological civilization construction, constantly improved laws and policies, strengthened scientific and technological support, and improved standards and norms, so as to promote the development of comprehensive utilization of resources industry, and made positive progress in various work. In 2019, the comprehensive utilization rate of bulk solid waste will reach 55%, 5% higher than that in 2015. During the 13th Five Year Plan period, a total of 13 billion tons of various bulk solid wastes were comprehensively utilized, and the land occupation was reduced by more than 1 million mu. The resources, environment and economic benefits were remarkable.
19、 During the period of the "14th five year plan", China will start a new journey of building a socialist modern country in an all-round way. The task of comprehensively improving the efficiency of resource utilization around the theme of promoting high-quality development is more urgent. Under the influence of resource endowment, energy structure, development stage and other factors, China's bulk solid waste will still face the severe situation of high production intensity, insufficient utilization and low added value of comprehensive utilization products in the future. At present, the accumulated storage of bulk solid waste is about 60 billion tons, and the annual new storage is nearly 3 billion tons. Among them, the utilization rate of red mud, phosphogypsum, steel slag and other solid wastes is still low, so the comprehensive utilization of bulk solid waste has a long way to go.
20、 In order to thoroughly implement the spirit of the Fifth Plenary Session of the 19th CPC Central Committee, further improve the level of comprehensive utilization of bulk solid waste and comprehensively improve the efficiency of resource utilization, the national development and Reform Commission took the lead in drafting the "guiding opinions", which defined the main areas and target requirements of comprehensive utilization of bulk solid waste in the new period, and proposed to promote the comprehensive utilization efficiency of bulk solid waste steadily and develop green The key tasks of the whole process promotion and technological model innovation and development are put forward, and the action of efficient utilization of resources is put forward to promote the comprehensive utilization of resources to achieve new progress.
21、

26、 A: The guiding opinions put forward five basic principles to promote the comprehensive utilization of bulk solid waste in the new period. One is to adhere to the combination of government guidance and market leadership. We will improve comprehensive policies and measures and give full play to the decisive role of the market in allocating resources. Second, adhere to the combination of scale utilization and high value utilization. We should actively expand the channels for comprehensive utilization of bulk solid wastes and continuously improve the added value of products for comprehensive utilization of resources. Third, we should adhere to the combination of absorbing stock and controlling increment. Scientific and orderly consumption of large amount of solid waste and strict control of new large solid waste pile stock. Fourth, we should adhere to the combination of highlighting key points and systematic governance. Strengthen the whole process management of comprehensive utilization of bulk solid waste, and promote the production, utilization and standardized disposal of waste.
