Green transformation, is it costly for companies?
In the Nanjing Economic Development Zone Environmental Protection Bureau staff and business representatives face-to-face seminars, business representatives are most concerned about the cost behind the green transformation, stuck in the development and environmental protection between this barrier, was expressed in the frown of business representatives.
As a large gathering of manufacturing industrial enterprises in the city, Nanjing Economic Development Zone has given solutions. VOCs governance is important, as is the development of enterprises. "Source substitution, facility renewal, process control, technical support" four initiatives are listed, reflecting the attitude and determination of the environmental protection department on the source of corporate VOCs management. In the process of promoting the precise management of VOCs, a number of source management benchmark enterprises have emerged, to explore the park to promote the source of pollution control has accumulated valuable experience.
Refrigerant switching, spray paint replacement
"There is an unavoidable spray painting operation link in our production process." The issue raised by Tianjia was highlighted in a working workshop in the Economic Development Zone. In this company's product manufacturing process, the use of refrigerant (refrigerant) and the painting operation link are the main sources of organic waste gas generation. "Run more and talk more." Gu Wei, a staff member of the Environmental Protection Bureau of the Economic Development Zone, showed his attendance records for almost every key enterprise in the area. Through active docking, field visits, combined with manual monitoring and analysis, research pollution treatment process, detailed interpretation of VOCs prevention and control policy, an "oil to water" improvement path is applied to the actual Tianjia company.
Oil to water? How to change? In the face of questions from enterprises, Wan Fangyu, a staff member of the Environmental Protection Bureau of the Economic Development Zone, explained, "The painting process will be fully switched from oil-based paint to environmentally friendly water-based paint, and the quality content of VOCs will be greatly reduced while the annual amount of paint used remains unchanged." After the implementation of the improvements, Tianjia achieved a decrease in annual VOCs generation of about 20 tons, further realizing pollution reduction and carbon reduction, and synergistic efficiency.
Prevention and control of ozone pollution, is a protracted war. Under the guidance of the Municipal Bureau of Ecology and Environment, the Environmental Protection Bureau of the Economic Development Zone, in accordance with the "Regulations on the Management of Ozone Depleting Substances" and other relevant regulations and policies, has been guiding the major refrigerant consumer Tianjia to carry out new refrigerant replacement work, and various types of environmentally friendly refrigerants have emerged to the fore. The project has recently passed the acceptance of experts organized by the Ministry of Ecology and Environment and the China Refrigeration and Air Conditioning Industry Association, and Zhang Tao, deputy director of the Environmental Protection Bureau of the Economic Development Zone, said that the project can further reduce the use of R22 refrigerant by about 91 tons per year.
R&D iteration, raw material upgrade
As the world's largest polarizer supplier, Sugene Photoelectric (Nanjing) Co., Ltd.'s factory in Nanjing Economic Development Zone has four pre-engineering production lines, making it the largest polarizer manufacturing base in the world in terms of capacity. "In the structure of polarizer, the pressure-sensitive adhesive that bonds the main body is crucial, but the coating process of pressure-sensitive adhesive will generate VOCs gas." Enterprise development can not stop, green environmental protection does not compromise. Through the opening area of the Environmental Protection Bureau, the Economic Development Bureau and other departments to strengthen the linkage, many times to the enterprise site to carry out research talks, and invited experts to help guide, to help open the source of Sugene photoelectric governance ideas.
"Start with raw materials." After investigating the process and other factors, Luo Changyin, head of the pollution prevention section of the Environmental Protection Bureau of the Economic Development Zone, gave such an opinion to Sugin Optoelectronics. Through the development and update of raw materials pressure-sensitive adhesive, to ensure the performance of the product while effectively reducing the generation of pollutants. After the idea was determined, Sugene Photoelectric completed the development of the second generation of pressure-sensitive adhesive, and quickly realized the replacement of raw materials for the product. Compared with the original first generation, the second generation of pressure-sensitive adhesive has reduced the amount of VOCs generated per unit by 10g/㎡, and the reduction ratio is about 13.6%.
"The development of environmentally friendly polarizers has earned us the 2021 China New Display Industry Chain Development Contribution Award - Green Low Carbon Award. This award means a lot to us!" said the person in charge of Sugene Photoelectric. The value of green development is seen and valued, so that enterprises can reap "green dividends" in the process of investing in environmental protection.
Intelligent control, process innovation
"Let the 'spokesman' of Chinese manufacturing in the field of rail vehicle door system in the world can also become the 'spokesman' of green development." On the concept of green development, Zhu Yongqiang, director of the Environmental Protection Bureau of the Economic Development Zone, reached a consensus with the corporate director of Nanjing Connie Electromechanical Co.
At the beginning of the construction of the smart factory, from the overall planning, the Environmental Protection Bureau of the Economic Development Zone helped to optimize the construction plan for source substitution and efficient management links. "Experts alone came in several waves." Professional advice for enterprises to seek, the Economic Development Zone Environmental Protection Bureau has repeatedly collaborated with experts to the project site to carry out research and exchange, listen to the demands of enterprises, to relieve enterprise problems, and make every effort to unblock the project declaration process to promote the implementation of the project.
"Point-to-point" guidance, "face-to-face" help, the construction of smart factories to fully implement the concept of intelligent production and green environmental protection, from the establishment of intelligent production system, real-time collection and analysis of workshop production status, energy consumption, material consumption, environmental protection emissions and other information. From the establishment of intelligent production system, real-time collection and analysis of workshop production status, energy consumption, material consumption, environmental protection emissions and other information, to the adoption of a number of mainstream advanced environmental protection technology, to ensure that pollution emissions from the source to the end of the closed-loop control. The intelligent factory project can help Konecranes to reduce the VOCs emission from the original 0.25kg/gate to 0.12kg/gate, a decrease of 50%.
"At present, the project has completed preliminary design and review, and is expected to be officially opened in 2024." In the future, the Economic Development Zone will also guide enterprises to create a green island for surface coating to promote industrial green transformation and high-quality development.
"Inspection + help, we hope to help enterprises and do our part for the blue sky." said the staff of the Atmosphere Department of Nanjing Ecological Environment Bureau. Run more to the enterprise, active service, lean forward service, has become the work of the ecological environment department of the normal. In recent years, Nanjing Ecological Environment Bureau has been increasing its efforts to help enterprises, through the dissemination of training on the latest environmental laws and regulations and management requirements, help check enterprise environmental protection management and other initiatives to help enterprises establish red line and bottom line awareness, to help enterprises green transformation.
"Promote the development of high-end, intelligent and green manufacturing industries." General Secretary Xi Jinping stressed when he attended the deliberations of the Jiangsu delegation at the first meeting of the 14th National People's Congress. At the end of this business and environmental protection face-to-face forum, this sentence has also become the consensus of those present, and those frowned at have gradually spread. "Environmental protection department to send services, green development is not absent." Between enterprise development and green environmental protection, more green dividends, more forward momentum.
