How does audit innovation illuminate the development path of the park? -- Jiangxi Dongxiang Economic and Technological Development Zone cleaner production audit innovation pilot exploration is underway
"With the expert group led by the Chinese Academy of Environmental Sciences to carry out detailed pollutant investigation and problem diagnosis for the enterprise in the early stage, and put forward a suitable improvement and rectification plan, we plan to carry out 17 cleaner production programs in the aspects of ingredient dust control, waste gas process optimization, VOCs collection and management, etc., which is expected to save about 168,000 yuan in electricity costs every year, reduce raw material loss by 0.524 tons, and reduce dust emissions by 0.565 tons. TVOC (Indoor Gaseous Organic Matter) reduces emissions by 56.809 tons, which can bring considerable environmental and economic benefits to enterprises. The relevant person in charge of Jiangxi Yongguan Technology Development Co., Ltd. introduced to reporters.
Going hand in hand with enterprises, the Dongxiang District Economic Development Zone (hereinafter referred to as Dongxiang Economic Development Zone) in Fuzhou City, Jiangxi Province is in full swing to carry out the pilot work of cleaner production audit innovation.
Since December 13, 2022, when it was selected as the first batch of cleaner production audit innovation pilots, in one year, Dongxiang Economic and Technological Development Zone has explored a "pilot-demonstration-establishment model" comprehensive industrial park cleaner production audit model through methodological innovation, pollution reduction and carbon reduction synergy and other measures.
The "old park" invited the national team
What are the problems of the long "case"?
According to reports, Dongxiang Economic and Technological Development Zone was established in 1992, covering an area of 23.4 square kilometers, and currently has three main industries: new materials, biomedicine, and electronic information. As of 2023, there are nearly 350 enterprises in the park, and more than 230 enterprises have been put into production, including 163 enterprises above the designated level.
"Dongxiang Economic and Technological Development Zone was established relatively early, and the park has accumulated many problems in its rapid development." The relevant person in charge of the Management Committee of Dongxiang Economic Development Zone said frankly that the more prominent problems are environmental management and industrial layout. Due to the phenomenon of emphasizing economy and ignoring environmental protection, the environmental management of enterprises is not in place, the staffing is insufficient, the technical support capacity is lacking, and the environmental risk prevention is heavy on emergency response and prevention, which has brought trouble to the environmental supervision work. At the same time, the layout of enterprises in the park is not reasonable, for example, there are chemical enterprises, ceramic enterprises, handicraft enterprises and machinery manufacturing enterprises and other industry enterprises in the southern area, all kinds of industries are mixed, although it can meet the park planning of "focusing on the development of pharmaceutical, fine chemical, machinery and other industries, and should introduce projects with high technical content, high added value and advanced technology", but can not achieve intensive development.
With the opportunity of being selected as the first batch of cleaner production audit innovation pilots, the Dongxiang Economic Development Zone Management Committee, the implementation party of the pilot project, invited a strong lineup: with the Chinese Academy of Environmental Sciences as the technical lead unit, and at the same time, the Jiangxi Huagan Environmental Group Research Institute was united to realize the combination of scientific research and technical strength of the "national-provincial platform enterprise", and jointly organized a total of more than 10 outstanding technical forces, including 5 senior titles, to take the pulse of the park as a whole and key industries and enterprises in the park. The investment amount is less than 500,000 yuan) and the medium/high cost plan (the investment amount is more than 500,000 yuan) is set up to further improve the production process, save costs, improve resource utilization, reduce waste emissions, and reduce environmental pollution.
For a time, Dongxiang Economic and Technological Development Zone can see various experts such as cleaner production experts, biomedical experts, chemical industry experts, building materials industry experts, textile industry experts, and environmental protection experts every day. Through their investigation and consultation of the "causes" of the park and enterprises one by one, a long "case" jumped on the paper.
The expert group entered the park and entered the enterprise for consultation
According to the relevant person in charge of the Chinese Academy of Environmental Sciences, on the whole, there are different degrees of room for improvement in the overall layout and industrial structure optimization, infrastructure construction, environmental risk prevention and control and monitoring system construction, environmental supervision system construction, and environmental ecological construction. From the perspective of enterprises, the enterprises in the park are more complex, lack of overall planning, enterprises are not related to each other and lack of ecological industrial chain, enterprises are fortified with each other in terms of technology and products, and fail to cooperate in the industrial chain, the upstream and downstream chains of products are cut off, and upstream enterprises cannot provide waste materials as raw materials to downstream enterprises, so that the waste recycling industry has no scale, and the high cost of technology and facilities makes the waste recycling system unable to form and resource recycling can not be realized. From the perspective of individual enterprises, the base of the situation of some enterprises in the park is still unclear, and the pollutants of core environmental elements such as "water, gas, and solid waste" involved in key industries with distinctive industry characteristics lack in-depth and detailed investigation and problem diagnosis, lack of scientific screening and excavation of key elements and common problems in key industries, and lack of assessment and evaluation of the cleaner production level of key industries in the park.
There is no prescription for the catch
The "three-level" and "four-stage" comprehensive park audit method is innovatively proposed
Only the symptomatic medicine can be prescribed. Different from the ready-made medicine when people are sick, the purpose and core essence of the pilot is to break through the bold innovation under the existing rules. Therefore, in the absence of a precedent for the prescription, the expert group led by the Chinese Academy of Environmental Sciences can only cross the river by feeling the stones first.
The expert group entered the park and entered the enterprise for consultation
"On the technical route, at present, China has carried out many years of mandatory cleaner production audit mode, through the process of 'pilot-demonstration-establishment model', the same successful experience of developed countries before also shows that it is completely feasible to implement a new cleaner production model through this model. Therefore, in the pilot exploration of promoting cleaner production through the overall model in Jiangxi Dongxiang Economic and Technological Development Zone, we also follow this route. The relevant person in charge of the Chinese Academy of Environmental Sciences told reporters.
It is understood that at present, the cleaner production audit is still limited to the level of a single enterprise, mainly for the mandatory audit of "double super, double have, high energy consumption" enterprises and the voluntary audit of general enterprises, and there is no system, methodology and case for the overall model of the park to promote cleaner production.
"There are problems such as the inability to discover the problems and potential of the park as a whole, the inability to improve the resource and energy cycle between enterprises, and the duplication of work for the separate audit of many similar enterprises in the industry." According to the relevant person in charge of the Chinese Academy of Environmental Sciences, therefore, the pilot is an innovative "three-level method" of the park cleaner production audit method, from the macro level (the park as a whole), the meso level (between enterprises), and the micro level (key industries and enterprises) through different ways and technical means to promote the improvement of the overall cleaner production level of the park, and help the green development of the park. The second is to simplify the audit process, simplify the integration and innovation of 35 steps in 7 stages to 15 steps in 4 stages, and explore efficient and time-saving cleaner production audit methods. Among them, "pre-audit + audit" was merged into "audit", "plan generation and screening + plan determination" was merged into "plan generation and feasibility analysis", and "plan implementation + continuous cleaner production" was merged into "plan implementation and continuous cleaner production".
According to the professional classification, China's industrial parks can be mainly divided into comprehensive parks (there are a number of key industries in the park) and professional parks (single industry in the park, such as electroplating parks), compared with professional parks, comprehensive parks in the park scale, output value, resource and energy consumption, environmental pressure, environmental management difficulties and other aspects are larger, industrial composition and distribution is more complex.
"Jiangxi Dongxiang Economic Development Zone is a typical comprehensive park, including Yuanshangang Industrial Park, Dongshan Industrial Park, and Science and Technology Incubation Park." According to the relevant person in charge of the Chinese Academy of Environmental Sciences, through combing, the expert team has screened out five key industries, including new energy and new materials, biomedicine, chemicals, building materials, textiles and garments, and through a comprehensive evaluation of energy consumption and pollutant emission levels in key industries, 47 key enterprises in key industries have been screened.
In the pilot work, the research team also tried to carry out collaborative innovation in pollution reduction and carbon reduction in industrial parks, optimize the spatial layout of the park, improve the use of new energy, promote the systematic cascade recycling of energy resources in the park, improve the comprehensive utilization of waste, and improve the level of green and low-carbon development of infrastructure according to the leading industries and the level of pollutants and carbon emissions in the park. At the same time, at the level of key industries and enterprises, through the "one line, one policy" and other methods, enterprises are urged to take measures such as process improvement, energy substitution, raw material substitution, energy conservation and efficiency, and comprehensive treatment, so as to realize the coordinated emission reduction of various pollutants such as air, water and solid waste and greenhouse gases in the "whole process" of production, and realize the improvement of the control level of pollutants and carbon emissions.
"The enterprises in the park are no longer fighting in isolation, but forming a cleaner production industry chain, optimizing the efficiency of material, energy and information exchange, and tapping the overall cleaner production potential of the park." The relevant person in charge of the Chinese Academy of Environmental Sciences pointed out.
“13”+“149”
How will the pilot change the park?
After a year of pilot work, the way and path of the development of Jiangxi Dongxiang Economic Development Zone have become clearer: clean, recycling, and resource utilization have been improved, the proportion of renewable energy use has increased to 5%, and the use rate of clean energy has increased to 30%. The pilot park establishes a cleaner production industry chain between enterprises at the inter-enterprise level, optimizes the efficiency of material, energy and information exchange between enterprises, and fully taps the overall cleaner production potential of the park.
Not only that, the expert group led by the Chinese Academy of Environmental Sciences has formed a total of 162 cleaner production problems and plans, including 13 at the macro level, all of which are medium and high-cost plans; There are 149 projects at the micro level, 112 no/low fee schemes, and 37 medium/high fee schemes, which promote the solution of new problems in the development of parks and enterprises.
According to the relevant person in charge of the park management committee, the investment and implementation of some specific rectification plans will also introduce the capital, technology and engineering operation advantages of Jiangxi Huagan Environmental Group (provincial state-owned environmental protection investment platform), which undoubtedly adds weight to the implementation of the guarantee plan.
"The key to prescribing a prescription is to see the 'efficacy', and the quantity, quality and feasibility of the cleaner production plan are directly related to the effectiveness of the cleaner production audit." The relevant person in charge of the Chinese Academy of Environmental Sciences commented on this year's work, thanks to the support of governments at all levels, the strong willingness of the park management committee and the strong combination of technical supporters, to ensure the quality and effectiveness of the cleaner production audit innovation pilot. In general, Jiangxi Dongxiang Economic and Technological Development Zone has passed the cleaner production audit innovation pilot, which has not only injected new momentum into the development of the park, but also provided experience for other regions to learn from.
According to their calculations, if the construction is implemented on schedule, the entire park can save 9.76 million yuan in operating costs, 34.642 million yuan in waste disposal costs, 424,000 yuan in fuel costs, 2.10387 million yuan in water costs, and 387,000 yuan in electricity costs, and the overall investment in the park can be reduced by 47.31687 million yuan per year.
While the economic benefits are significant, the environmental benefits are also prominent. If the construction is implemented on schedule, the entire park can save 840,000 m3 of water, 1,060 tons of fuel, 141.644 tons of COD, 7.597 tons of ammonia nitrogen, 1.73 tons of total phosphorus, 253.5 tons of SO2, 77.175 tons of NOx, 141.261 tons of dust, 111.099 tons of TVOC, 23,000 tons of hazardous waste, 3,590,520 tons of solid waste, and 0.14 tons of odor per year. The effect of energy saving and emission reduction such as annual reduction of methane by 0.013 tons.
