Industrial transfer increases the risk of hazardous waste. The industry suggests that "reduction and recycling" should be given priority.

release date: Source: the disposal of solid waste, especially hazardous waste, is imminent and has become a huge risk source affecting economic and social development

the 17th meeting of the Standing Committee of the 13th National People's Congress will be held in Beijing from April 26 to 29. Several draft laws, including the third review of the revised draft law on the prevention and control of environmental pollution by solid waste, will be submitted for deliberation

yuezhongming, spokesman of the legal work committee of the Standing Committee of the National People's Congress and director of the legislative planning office, introduced on the 22nd that the revised draft of the law on the prevention and control of environmental pollution by solid waste was reviewed for the third time. The main amendments include effectively strengthening the management of medical waste, especially medical waste in response to major infectious diseases, further improving the prevention and control measures for environmental pollution by domestic waste and the provisions on the prevention and control of environmental pollution by construction waste, and increasing the control of excessive packaging The management of plastic pollution

recently, many people in the industry told China business that the principle of "reduction and recycling" should be further clarified, requiring enterprises to adopt cleaner production processes to prevent and reduce the generation of hazardous wastes, focus on comprehensive utilization, and maximize the conversion of solid wastes into products or by-products. At the same time, we will speed up the construction of disposal capacity in areas with large amount of hazardous wastes and insufficient disposal capacity

solid waste is increasing year by year

on April 22, the State Council steering group reported to Jiangsu province that the systematic safety risks of Jiangsu chemical industry are large, the risks of traditional high-risk industries are concentrated, the new safety risks are prominent, and the hidden dangers of major problems can not be ignored

on March 21, 2019, Jiangsu Xiangshui tianjiayi Chemical Co., Ltd. illegally stored hazardous wastes for a long time, resulting in spontaneous combustion and explosion. This particularly serious production safety accident caused 78 deaths and 76 serious injuries, with a direct economic loss of nearly 2billion yuan

according to the 2019 annual report on the prevention and control of environmental pollution by solid waste in large and medium-sized cities nationwide published by the Ministry of ecological environment on December 31, 2019, a total of 200 large and medium-sized cities nationwide released the prevention and control information of environmental pollution by solid waste in 2018. According to statistics, the amount of general industrial solid waste in large and medium-sized cities that released information was 1.55 billion tons, and the amount of industrial hazardous waste was 46.43 million tons. The amount of medical waste used in the static tensile performance test of materials and parts was 817000 tons, and the amount of domestic waste was 211473000 tons

duxiangwan, academician of the Chinese Academy of engineering, introduced that China produces nearly 10billion tons of solid waste every year, which is increasing year by year. Such a huge accumulated solid waste stock and annual output, if not properly treated and utilized, will cause serious pollution to the environment and a great waste of resources. At the same time, the total amount of historical solid waste storage in China is as high as 60billion to 70billion tons. In some areas, the siege of cities and the littering of garbage have become the pain of the people and the trouble of the people's livelihood

last year, the Ministry of ecology and environment issued "on improving the ability of hazardous waste supervision, utilization and disposal and environmental risk prevention", which proposed that by the end of 2025, a hazardous waste environmental supervision system of "strict prevention at the source, strict management in the process and strict punishment in the consequences" should be established and improved; The utilization and disposal capacity of hazardous wastes in all provinces (autonomous regions and municipalities) basically matches the actual demand. The national utilization and disposal capacity of hazardous wastes and utility households have no choice but to purchase expensive imported products, so they need to be generally balanced, and the layout tends to be reasonable; The ability to prevent environmental risks of hazardous wastes has been significantly improved, and the high incidence of illegal transfer and dumping of hazardous wastes has been effectively curbed

the three-year action plan for special rectification of national work safety issued by the safety committee of the State Council recently also requires that hazardous waste safety rectification be carried out, hazardous waste screening be carried out in an all-round way, solid waste with unknown attributes be identified, and the possible problems of illegal stockpiling, random dumping and private landfilling of hazardous waste in chemical parks, chemical enterprises and hazardous chemical units be focused on

the treatment and disposal of hazardous wastes are difficult.

the chemical industry is the first source industry of hazardous wastes in China. Zhuangshangning, deputy director of quality, safety and environmental protection department of China Petroleum and Chemical Industry Federation, told China first finance and economics that according to the current national directory of hazardous wastes (2016), China's hazardous wastes include 46 categories and 479 sub categories, including 28 categories involving petrochemicals. 2. The surfaces of unpainted exposed parts of laboratory machines should be often coated with anti rust oil, accounting for 56%. There are 226 waste codes, accounting for 45%

according to Zhuang Xiangning, due to the variety of raw materials and side reactions in the chemical production process, the composition of waste generated is complex, especially the problem of fine distillation residue in the fine chemical industry

according to preliminary statistics, China produces more than 20million tons of fine (steam) distillation residues every year, more than 80% of which come from the petroleum and chemical industry. Its composition is extremely complex, including raw materials, products and intermediates. Some residues (liquids) contain a large number of toxic and harmful substances, and even contain persistent organic pollutants, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, etc. these organic pollutants are environmentally persistent Volatile, highly toxic, bioaccumulative, reactive and other characteristics, if not strictly managed, will inevitably cause serious harm to human health and the ecological environment

and the treatment and disposal of hazardous wastes is also very difficult. For example, chromium slag contains a certain amount of heavy metal hexavalent chromium, which is difficult to detoxify. Downstream enterprises are unwilling to make comprehensive use of it, and illegal dumping of chromium slag has occurred many times in history. A large number of waste acid, waste salt, etc. have become a high incidence area of illegal disposal of hazardous wastes due to their inability to be landfilled and the lack of technically feasible and economically reasonable comprehensive utilization technologies

Fang Jianzhong, deputy general manager and chief technical supervisor of the hazardous wastes and medical wastes division of tus environmental remediation center, reported that at present, the mainstream hazardous wastes disposal process has not reached a very mature level, and the incineration process is relatively mature, but there are problems in production stability, continuity, equipment failure rate, etc., and there are prominent problems in the adaptability of physicochemical processes to hazardous wastes

according to zhouxianhui, President of China Association of chemical industry and environmental protection, due to the lack of qualified units for hazardous waste disposal in some places, the insufficient capacity for hazardous waste disposal and utilization, and the lack of market competition, the cost of hazardous waste transfer and disposal of waste producing enterprises has been rising, and even exceeded the price of the produced chemical products, bringing huge cost pressure to the production and operation of enterprises

some enterprises reported that it is difficult for waste enterprises in Jiangsu, Anhui and Guangdong to find qualified hazardous waste disposal units. The scarcity of disposal facilities has led to an increase in the disposal price of hazardous waste by 20%~30% every year. At present, the price of incineration waste is 5000~10000/ton, 20~40/empty barrel cleaning, and about 10000/ton of cleaning waste liquid treatment

in addition, hazardous waste transfer procedures are time-consuming, cumbersome and inefficient. In particular, when hazardous waste is transferred across provinces, it usually takes months to complete the transfer procedures. In addition, it takes two weeks to prepare the materials, and it takes months to receive the duplicate receipt. The completion of the whole procedure takes months, resulting in a long time for temporary storage of hazardous waste after it is generated, which also increases the environmental risk

hexubin, an expert of the emergency management department and deputy general manager of Zhejiang Longsheng Group Co., Ltd., told us that in recent years, some small and medium-sized private dye enterprises in Jiangsu and Zhejiang have been admitted to the park as "major opportunities" in the northwest and other inland areas because they do not have a perfect circular economy industrial chain, and the waste acid and other hazardous wastes they produce cannot be used as resources in an effective and low-cost way, This kind of industrial transfer has great hidden dangers of safety and environmental protection

priority should be given to "reduction and recycling"

Zhuang Xiangning suggested that at present, the resource utilization of hazardous wastes should be strongly encouraged. In view of the current problems of insufficient incineration capacity, shortage of landfill resources, limited comprehensive utilization and secondary pollution caused by disposal process, which push up the disposal cost of hazardous wastes, the principle of "reduction and recycling" is further clarified. Enterprises are required to adopt cleaner production technology to prevent and reduce the generation of hazardous wastes, focus on comprehensive utilization and recycling, and maximize the conversion of solid wastes into products or by-products, Make the best use of everything. At the same time, simplify the approval and transfer of hazardous wastes, and their radar observability is relatively low

outside the Gulf (recyclable), all of them are entrusted to the member enterprise Gulf New Materials Technology Co., Ltd. for disposal

hexubin believes that at the moment of serious overcapacity of dyes, the whole country should play a game of chess, support the leading dye enterprises with a good foundation of circular economy through the visible hand of the government, and give full play to the maximum utility of resources under the conditions of limited land, sewage discharge and hazardous waste disposal nationwide, so as to effectively reduce hazardous waste and make supervision efficient and transparent

caochengyu, consultant of China Pesticide Industry Association, believes that on the one hand, the environmental protection department should strictly abide by the relevant national and local standards, and should not accept the relocation of relevant enterprises in places that do not meet the conditions. On the other hand, it should increase investment, expand capacity and improve treatment technology

the person in charge of a fine chemical enterprise in Jiangsu also told China first finance and economics that the construction of disposal capacity should be accelerated in areas with large amount of hazardous wastes and insufficient disposal capacity, and the western region should coordinate the transfer of hazardous wastes from the eastern region to the western region. Promote resource sharing within the same region. Support enterprises to participate in the disposal and resource utilization of hazardous wastes and reduce the generation of hazardous wastes. Qualified enterprises shall exempt the intermediate products and by-products produced in the production process and listed in the list of hazardous wastes

the responsible person also suggested to further strengthen the dynamic management of the national list of hazardous wastes. After the hazardous wastes listed in the list have been demonstrated or identified by the industry association as not having the characteristics of hazardous wastes, they should be removed from the list or included in the exemption list in time to reduce the disposal costs of enterprises and society
