At the beginning of 2025, the Ministry of Industry and Information Technology "2024 annual green manufacturing list", the provincial Department of Industry and Information Technology "2024 Jiangsu Province Green Factory (the fifth batch) shortlisted list" announced one after another, the city ofAdd 7 national green factories, 2 national green industrial parks, 1 green supply chain management enterprise and 40 provincial green factories.The
In recent years, the city's enterprises, parks from the production, technology, management and other dimensions of the full range of green development road, and continue to build a green manufacturing system, so that the economic development of the "green content" rising. A few days ago, the reporter went into a number of newly selected green factories, green industrial parks for field visits.
"Green Train" Approaches Citizen's Side
At the end of last year, a touch of "new green" to the public side - known as the "transfer king" of the Nanjing Metro Line 7 line opened for operation, linking up the old and new city. 7 line logo color for the grass green. Grass green, in fact, the train production process is also full of "green elements".
Into the train "birthplace" of the CMC Nanjing Puzhen Vehicle Co., Ltd. body sub-factory production workshop, automatic paint spraying robot is waving a mechanical arm, precise spraying operations on the body. Although the spraying volume is large, but the scene almost do not smell the strong smell of paint.
As it turns out, the company has realized the replacement of solvent-based coatings with water-based coatings for all spraying processes. Compared to traditional solvent-based coatings, the full application of water-based coatings greatly reduces the amount of volatile organic compounds entering the air, while also taking into account the economy through the combination of efficient spraying processes and material savings.
"After the use of electrostatic automated spraying equipment, compared with the past, the use of single-vehicle paint to save at least 20%. According to statistics, in the domestic railroad bus and urban rail vehicle manufacturers, we have the highest proportion of water-based paint application." CNR Nanjing Puzhen Vehicle Co., Ltd. safety and environmental department of the relevant person in charge of the introduction, the company from the source of raw material selection, process process process control to the end of the volatile organic compounds (VOCs) emissions treatment, are used in the industry's advanced process technology, comprehensively enhance the level of green manufacturing technology, and at the same time, the establishment of a green supply chain management platform, and the joint upstream and downstream together to build a green production model.
Green factory is the core basic unit of green manufacturing, with land intensification, harmless raw materials, clean production, waste resourcefulness and low-carbon energy as the construction goal. This time, CSR Nanjing Puzhen Vehicle Co., Ltd. was selected to the list of national green factories.
Going international with a "green license" in hand
In the production plant of Nanjing Panda Electronics Manufacturing Co., Ltd, which is a subsidiary of Nanjing Panda, the reporter found that energy-saving lighting equipment is used here, and the solid waste generated in the production process is transformed into clean energy after treatment and used in the production again to realize the recycling and sustainable development of solid waste, and the comprehensive utilization rate reaches 1,00%; in the office area, the implementation of the paperless office using information technology has become a daily routine; in the workers' living area, the water saving rate reaches more than 50%. In the office area, the paperless office has become a daily routine by utilizing information technology; in the workers' living area, the water saving rate reaches more than 50%.
Zhao Chunxia, deputy general manager of the manufacturing center of Nanjing Panda Electronics Manufacturing Co., Ltd. introduced that the enterprise has long been in the layout of the construction of green factories, and has taken various measures to carry out various forms of tapping the potential to increase efficiency activities, point "green" into "gold", and last year, it obtained ISO50001 Energy management system certification, "green factory evaluation system certification covers a number of dimensions, whether it is energy efficiency, waste management, or clean production, product life cycle management, etc., the enterprise put forward a full range of requirements."
In the context of the global promotion of green development, the construction of green factories is like holding a "green license plate", which is the "admission ticket" to fight for a broad global market, and also a "plus point" to stand out in the competition in the industry. It is also a "plus point" to stand out in the competition of the industry.
At the end of last year, Nanjing Panda Electronics Manufacturing Co., Ltd. produced 3.5 million sets of Bosch, Siemens and other brands of white goods customers supporting products, sales revenue increased sharply year-on-year 50%, becoming a vivid evidence of its point "green" into "gold". "At present, we have become Bosch, Siemens and other world-renowned enterprises 'green partner', the future will also work with them to promote green and sustainable development plan, in the global market to send out the 'green voice. " Zhao Chunxia said.
From "a plant" green to "full of" new
The day the weather was fine, located in Nanjing Economic and Technological Park, Nanjing Electric, the reporter saw the roof of the plant is equipped with 18,000 pieces of solar modules, composed of a large-capacity "rechargeable treasure", continue to convert light energy into electricity.
Before the Spring Festival of the Year of the Snake, Nanjing Electric received a large order from the State Grid and is currently producing at full capacity. "As early as 2020, we and the South China Power Grid comprehensive energy cooperation, to start the construction of distributed photovoltaic power generation project, the year November grid into operation, the current daily power generation capacity of about 35,000 kilowatt-hours, in addition to self-consumption of electricity are all delivered to the national grid." Nanjing Electric relevant person in charge of the introduction.
Nanjing Economic Development Zone is the earliest development zone in the city to be recognized as a national green industrial park. As a platform for green factories and green infrastructure clustering, Nanjing Jiangning Binjiang Economic Development Zone and Nanjing Pukou Economic Development Zone were successfully selected in the list of national green industrial parks for the year 2024.
How can a large-volume park "contain new" and "spit green"? Data show that in recent years, Pukou Economic Development Zone, planning and construction of photovoltaic power generation, chemical energy storage project 36, of which the photovoltaic project is expected to generate 69.6 million kilowatt-hours of electricity, equivalent to 8562.89 tons of coal, can reduce carbon dioxide emissions of about 69,400 tons per year; wastewater treatment plant 2024 wastewater treatment volume of 15,970,900 tons, water reuse rate of 73.7%; Environmental Protection Industrial Park industrial solid waste utilization volume of 268,300 tons, comprehensive utilization rate of 88.49%.
"Green is the distinctive feature of the new quality productivity itself, the fundamental orientation of the development of new quality productivity, and the inevitable result of the development of new quality productivity." Pukou Economic Development Zone, said the park introduced the Nanjing Pukou Economic Development Zone Carbon Peak Carbon Neutral Action Plan to promote the rapid growth of the green economy.
