Express packaging, plastic products, scrap cars, scrap electronics…With the rapid development of economy and society, the production of solid waste is increasing rapidly.How to minimize the impact of solid waste on the environment so that people no longer face garbage siege?In this year’s report on the work of the provincial government, the construction of “waste free cities” in the whole region has been listed as a key task of this year.At the beginning of the year, the General Office of the Provincial Government issued the Work Plan of “Waste Free City” Construction in Jiangsu Province. The Plan showed the “blueprint” : by 2025, the construction task of “waste free city” in Jiangsu Province will be completed, and more than 4 cities divided into districts will be built into national “waste free city”.The intensity of solid waste generation has been rapidly reduced, the level of comprehensive utilization has been significantly improved, and the capability of harmless disposal has been effectively guaranteed, basically realizing a network of solid waste management information.What is a “waste free city”?How to build “waste free city”?Xinhua Daily · Interchange reporters visited.Kitchen waste disposal point in Suzhou Industrial Park Environmental infrastructure Recycling Industrial Park, kitchen waste has become a green “treasure”, the utilization rate of 94%.”After a series of processes, the biogas produced by the kitchen waste is purified and turned into natural gas. The solid residue is partly used for organic composting, and partly burned to generate electricity after being dried in a sludge plant.”Every ton of food waste can produce 60 cubic meters of natural gas and reduce carbon emissions by about 0.75 tons.”Wei Zhanfeng, general manager of Suzhou Industrial Park Qingyuan Huayan Water Co., LTD.This exploration is an epitome of jiangsu solid waste comprehensive utilization.”Waste free city” refers to an urban development model that minimizes the environmental impact of solid waste by promoting the formation of a green way of production and life, and continuously promoting the reduction of solid waste at its source and the recycling of solid waste.In December 2018, The General Office of the State Council issued the Work Plan for the Pilot Construction of “Waste Free City”, and Xuzhou, Jiangsu Province, was selected as one of the first national pilot cities.With the rapid economic development and accelerated urbanization process in Jiangsu, the annual production of solid waste exceeds 300 million tons, resulting in great environmental risk and pressure.Nanjing university, professor, school of environment, doctoral supervisor xiao-dong zhu believed that in recent years, the ecological environmental quality in jiangsu best level since new century, but the entire province structural contradictions are still outstanding, “heavy”, “coal” energy structure, industrial structure “intensive development” spatial structure have not changed, the environment capacity overload, the situation of ecological cost overdraft have yet to be fundamentally reversed,It is timely to launch the construction of a “waste free city” in the whole region.Jiangsu has a practical basis for exploring the construction of “waste free city” : In terms of hazardous waste, it has explored the centralized collection of small amounts of hazardous waste, built a monitoring system for the whole life cycle of hazardous waste, and significantly improved the supervision ability of the whole process.In terms of general industrial solid waste, coordinated utilization of various industrial solid wastes has been promoted, and the utilization and disposal rate has been stabilized at over 90%.In terms of household garbage, we have promoted the construction of garbage sorting, collection and treatment facilities in urban and rural areas in a coordinated way, leading the country in garbage processing capacity.The reporter found that for the construction of “no waste city”, jiangsu many places have a layout, “no waste city” construction into the fast lane.Zhang Zhimin, director of pollution prevention department of Nanjing Ecological environment Bureau, said that Nanjing is actively applying for the construction of “waste free city” during the 14th Five-year Plan period.Prior to this, Nanjing Municipal Bureau of Ecology and Environment and relevant departments have carried out extensive research in pilot cities such as Shaoxing, Chongqing and Xuzhou, learning the experience of shaoxing’s “waste-free city” informatization full-cycle supervision and Chongqing’s “waste-free city cell” guiding green development.On this basis, nanjing took the lead in formulating the “Waste Free City” Construction Work Plan in Nanjing.The abandoned door core board has been made into a bookshelf, the old door frame has become a bench, the books are left by senior seniors, the art materials that decorate the wall come from deciduous branches, plastic bottles, waste cartons…This is the “no waste bookstore” of Xuzhou No.1 Middle School.At present, xuzhou has built 32 such “no waste book houses”.In addition to source reduction, recycling is also an effective means of reducing solid waste.”Boom boom”, with a rhythmical running sound, black activated carbon from the machine spit out.In Xuzhou Xunhuan industrial park, a renewable resources technology Co., LTD., using thermal regeneration process, will be a ton of waste activated carbon into recycled activated carbon into the market.The waste activated carbon generated by xuzhou industry is concentrated here for recycling, which can reduce carbon dioxide emissions by 70,000 tons every year.Circular economy industrial park is an important support project for the construction of “waste free city” in Xuzhou.Not only waste activated carbon, kitchen waste, medical waste plastics, etc., can be “eaten dry pressed clean” in the recycling industrial park.At present, the industrial park has built and operated a garbage incineration power plant that can handle 2,250 tons of household garbage per day, a food and kitchen garbage treatment plant of 366 tons, and more than 10 projects such as construction waste disposal and hazardous waste material disposal have been successfully put into operation.”In the past, solid waste disposal and utilization projects were mostly built independently, and there were widespread problems such as geo-spatial fragmentation of facilities, high cost of collaborative disposal and secondary pollution of by-products.”Lv Xuanhui, general manager of Xuzhou Xinsheng Luyuan Circular Economy Industry Investment and Development Co., LTD., introduced that the circular economy industrial park takes full account of the technological synergy and scale matching of different projects to improve operation efficiency.The spread of “waste free culture” from schools to families, agencies and factories has made the “waste free concept” of reduction, resource utilization and harmlessness widely recognized in Xuzhou.The results of nearly 60,000 questionnaires show that the penetration rate of publicity, education and training for the construction of “waste free city” in Xuzhou is 98.06%, and the public is 96.88% satisfied with the construction effect of “waste free city”.Compared with the requirements of various indicators, Xuzhou overfulfilled the predetermined task and was fully affirmed by the Ministry of Ecology and Environment.”Through several years of efforts, xuzhou, a century-old coal city, has achieved transformation and rebirth.”Yuan Yiqing, party member and chief engineer of Xuzhou Ecological environment Bureau, introduced that the city reduced a total of 7,300 hectares of abandoned industrial and mining areas, and absorbed and utilized more than 11 million tons of coal gangue, waste stone (slag) and 2.7 million cubic meters of solid waste such as urban construction waste.Some 16,700 hectares of coal mining subsidence areas, including Pan ‘an Lake and Jiuli Lake, and more than 100 quarrying sites, including Jiuli Mountain and Tuolong Mountain, have transformed from “urban waste” to “urban lung”.In addition, Xuzhou innovatively built an intelligent management platform of “waste management with wisdom” that included the whole process data of solid waste from five sources, and built 42 hazardous waste management units with an annual hazardous waste disposal capacity of 344,690 tons.To build a “waste free city” with local characteristics in accordance with local conditions is an important measure to promote the synergy of pollution reduction and carbon reduction. It is also a beautiful and arduous work.Jiangsu’s “plan” proposes to adhere to innovation-driven, spare no effort to build a “waste free city” local characteristics.”We will develop a waste-free city based on local conditions.”Zhang Zhimin introduced, for example, in view of nanjing’s industrial structure is heavy, there are many industrial parks, focus on the implementation of nanjing’s key industries such as steel, petrochemical and green transformation, carry out industrial park recycling transformation, promote efficient allocation of resources.In addition, combined with the advantages of Nanjing’s abundant scientific and educational resources, artificial intelligence, computer and other industrial clusters, it promotes the construction of power battery recycling and utilization network, information trading platform for comprehensive utilization of construction waste, intelligent joint supervision platform for “waste free city” and other platforms, so as to realize the “Internet +” innovative management mode in solid waste field.The reporter learned that “Wuxi city” “waste free city” construction work plan will be officially issued, which clearly proposed to build a national “waste free city” by 2025.”The construction of ‘waste free city’ will closely combine wuxi’s economic development, industrial structure and regional characteristics.”Luo Xiaochun, director of solid waste and chemicals department of Wuxi Ecological Environment Bureau, said, “Wuxi is a pearl of Taihu Lake. In the future, it will combine the construction of ‘waste free city’ with the treatment and utilization of organic waste in urban and rural areas around Taihu Lake.It is not only the last few demonstration projects, but also the whole chain to consider how to better reduce the source, and how to coordinate with the processing capacity of general industrial solid waste or domestic waste in collection, utilization and disposal, so as to provide reference for the treatment and utilization of organic waste in urban and rural areas of the Yangtze River Delta.In addition, aiming at the difficult problem of hazardous waste collection and disposal of small and micro enterprises, Wuxi has promoted the green island pilot project of hazardous waste collection and disposal of small and micro enterprises. Next, it will be further expanded to non-industrial enterprises, enterprises and institutions to ensure that all hazardous waste can be collected.”Provincial department of Ecology and Environment fixed management center related person in charge said that the next step, will develop jiangsu province, the whole “no waste city” construction index system.At the same time, will jointly with the relevant departments at the provincial level for local implementation of technical guidance, formulate implementation plan of “one city and a slip”, speed up the repair JiGu waste comprehensive treatment infrastructure, in waste, medical waste collection system construction and FeiYan, fly ash, medical waste incineration using disposal ability on a breakthrough,Make the general solid waste, dangerous waste resource utilization industry bigger and stronger, so that the beautiful Jiangsu more green.Xinhua Daily · Intersection point reporter Xu Haiyan Xinhua Daily all media economic News department produced a statement: this article copyright belongs to the original author, if there is a source error or infringement of your legitimate rights and interests, you can contact us through the mailbox, we will be processed in a timely manner.Email address: jpbl@jp.jiupainews.com
