Taizhou Bay Economic and Technological Development Zone was selected by the Ministry of Ecology and Environment as the first batch of national-level pilots for collaborative innovation in pollution reduction and carbon reduction.
Under the "dual carbon" goal, the synergy of pollution reduction and carbon reduction is the fundamental strategy to solve pollution and climate problems, and it is also the only way to achieve high-quality economic development.
In November 2021, the Medical and Chemical Park of Taizhou Bay Economic and Technological Development Zone was selected as the first batch of provincial pilot projects for pollution reduction and carbon reduction. Not long ago, the Ministry of Ecology and Environment released the first batch of pilot projects for coordinated innovation in pollution reduction and carbon reduction in cities and industrial parks, and Taizhou Bay Economic and Technological Development Zone was successfully selected, becoming one of the first four industrial parks selected in Zhejiang Province and the first pilot industrial park in Taizhou City.
In recent years, the Management Committee of Taizhou Bay Economic and Technological Development Zone has taken the lead in exploring institutional innovation, waste gas adsorption and recovery, and wastewater quality classification and reuse, and has successively planned and implemented 23 key projects for synergy in pollution reduction and carbon reduction, with a total investment of 3.71 billion yuan, achieving carbon reduction of about 273,000 tons, and effectively building a whole-process, all-round and full-chain collaborative path for pollution reduction and carbon reduction in the medical and chemical industry.
Password 1: Industrial upgrading
As a "green pharmaceutical capital", Linhai has a long history in the medical and chemical industry. From the Shuiyang Chemical Industry Zone in the early 90s of the last century to the establishment of the coastal chemical industry park at the end of the 90s of the last century, until August 2001, with the approval of the former State Planning Commission and the Economic and Trade Commission, the Linhai Medical and Chemical Park was officially established.
Taizhou Bay Economic and Technological Development Zone Medical and Chemical Park is the core area of Linhai Medical and Chemical Park, and is also one of the world's largest pharmaceutical intermediates production areas, a national pharmaceutical intermediates and API production area, and the only modern pharmaceutical manufacturing model transformation demonstration park in Zhejiang Province.
With its profound heritage and first-mover advantage, Taizhou Bay Economic and Technological Development Zone vigorously promotes the traditional medical and chemical industry, transforms to new energy fission, transforms to new materials, and upgrades to high-end preparations (medical devices). Taking Aoxiang Pharmaceutical as an example, from intermediates to APIs, to innovative drugs and CDMO (pharmaceutical contract research and development and production institutions) business, the company's business segment has been continuously strengthened and expanded, and its business has grown by more than 30% every year, and preparations have been sold to more than 60 countries and regions.
From "medical chemistry" to "medicine and health", this is one of the paths for industrial upgrading and breakthrough. In accordance with the principle of "eliminating and withdrawing a batch, merging and optimizing a batch, and rectifying and upgrading a batch", Taizhou Bay Economic and Technological Development Zone has withdrawn more than a dozen synthetic leather enterprises, merged and reorganized several chemical enterprises, and rectified and upgraded medical and chemical enterprises. At present, walking into the shore of Taizhou Bay, rows of cranes are lined up, and the construction of "medicine and health" industrial projects is in full swing.
Zhejiang Yongtai New Energy Materials Co., Ltd. introduced the "Yongtai New Energy Materials Industrial Park Project", with a total investment of more than 10 billion yuan, which will build a one-stop supply base for lithium battery materials around new energy materials and add new vitality and new momentum to Taizhou's economic development.
Hisun Group Hichuangda Biomaterials Co., Ltd. has an annual output of 150,000 tons of polylactic acid project, and the construction is accelerating. The total investment of the project is about 1.3 billion yuan, and the annual output value is expected to be about 3.45 billion yuan after reaching production, which can promote the iterative renewal of the degradable biomaterials industry.
Zhejiang Shaxing Bohai Technology Co., Ltd. with an annual output of 1,600 tons of cyclopropylamine and other APIs project is also about to be completed, which will have an annual production capacity of 1,600 tons of cyclopropylamine, 300 tons of cyclopropylcarboxylic acid and other APIs and intermediates, and can achieve an annual output value of 2.7 billion yuan after reaching production.
To accelerate the innovation and upgrading of the medical and chemical industry, it is also necessary to break through in technology. In recent years, Taizhou Bay Economic and Technological Development Zone has actively promoted advanced technologies such as enzyme catalysis, microchannel, and tubular reaction. Compared with the traditional chemical synthesis process, the enzyme-catalyzed green process shortens the reaction steps, reduces the steam consumption per ton of product by 30%, reduces the electricity consumption by 17%, and reduces the organic solvent consumption by 40%. Pharmaceutical companies such as Abiochem (Taizhou) Pharmaceutical Co., Ltd. and Zhejiang Hongyuan Pharmaceutical Co., Ltd. (Company) have gradually eliminated the traditional chemical synthesis process and adopted the enzyme catalytic process.
At present, Linhai modern pharmaceutical industry has formed a complete industrial chain of "intermediates-APIs-preparations", with the conditions and foundation for the large-scale and ecological development of APIs and the deep extension of downstream preparations, and is making every effort to build an innovative highland for the pharmaceutical industry with global influence. With the Modern Pharmaceutical and Chemical Service Innovation Park as the carrier, Taizhou Bay Economic and Technological Development Zone has also introduced industry-university-research platforms such as Taizhou University Toumengang Industrial College to promote the iterative upgrading of the medical and chemical industry.
Password 2: Smart management
At present, the application scenarios of the industrial Internet are constantly enriched, and digitalization has become an inevitable choice to promote the transformation and upgrading of traditional industries. In recent years, Linhai City has focused on the digital transformation of enterprises and the integration of industrial chain resources, and built the core architecture of "industrial brain + future factory" to help enterprises invest in the wave of digital transformation.
In May 2022, the "Chemical API Industry Brain" platform was launched, and the enterprise side mainly includes three major sectors: new intelligent manufacturing applications, common technologies and industrial ecology. Among them, the new intelligent manufacturing application sector is based on solving the digital divide of enterprises, creating applications such as inspection management, energy management, laboratory information management, and equipment management, and providing platform-based solutions in terms of safety and environmental protection.
In medical and chemical enterprises, safety is the lifeline. All kinds of reactors, pressure storage tanks, valves and other equipment have a certain service life, and if they are overused, the aging of the equipment will bury potential safety hazards, so equipment management is very critical. Linhai Jianxin Chemical Co., Ltd., a subsidiary of Sunrise Group, plays an important role in the domestic methyl bromide market. From the beginning of its establishment, Jianxin Chemical has been equipped with an equipment management system, but it still relies on manual labor, and the technical level and sense of responsibility of workers affect the quality of equipment management.
After adopting the equipment management application of the "brain of the chemical API industry", the company digitally manages various equipment, all equipment information is entered into the system, and key equipment is monitored in real time with sensors. When the equipment should be maintained, which parts need to be replaced, and which consumables need to be replenished, the system automatically reminds you that the health status of the equipment is clear at a glance.
In the medical and chemical park of Taizhou Bay Economic Development Zone, there are many enterprises involved in the loading and unloading of hazardous chemicals, and a large number of hazardous chemical vehicles enter and leave the park every day, and the phenomenon of gathering, detention and disorderly parking in the process of loading and unloading hazardous chemical transport vehicles occurs from time to time.
In response to this situation, the Management Committee of Taizhou Bay Economic Development Zone and the Linhai Municipal Transportation Bureau jointly created a "priority card" scenario for the loading and unloading of hazardous chemicals vehicles in the medical and chemical park, which improves the efficiency of loading and unloading and reduces the safety risks and hidden dangers in the process of loading and unloading hazardous chemicals through procedures such as appointment calling, intelligent operation, and risk prediction.
On the smart supervision platform of the medical and chemical park of Taizhou Bay Economic Development Zone, the reporter saw that on the electronic large screen, the information of vehicles, hazardous chemical appointments, and transported goods in the park was clear at a glance, and the staff was busy processing the early warning information issued by the platform.
"Digitalization is a real time saver. Zhejiang Haichang Gas Co., Ltd. driver Master Chen told reporters that in order to load and unload goods in the front factory, vehicles on the roads in the park are lined up in long queues, they have to wait for at least half an hour, and now the mobile phone terminal appointment is very convenient, and the work efficiency has been greatly improved.
Digital intelligent management strengthens the connection and collaboration between upstream and downstream enterprises, industries, government and enterprises, and enterprises and societies in the industrial chain, and can reduce energy consumption per unit of added value. By building a digital and intelligent management platform for pollution reduction and carbon reduction, Taizhou Bay Economic and Technological Development Zone has also implemented differentiated policies for enterprises in the allocation of resource elements such as land, electricity, energy, water, gas, and credit. At the same time, it strengthens the statistical analysis of pollutant emissions and carbon emissions of enterprises, and forms "three lists" of key carbon emission units, key pollutant discharge units, and key energy-using units, so as to achieve visual, quantifiable and precise management, and guide enterprises to improve pollution reduction and carbon reduction measures.
Password 3: Project planning
Lucid waters and lush mountains are invaluable assets. Reducing pollution and carbon emissions is to promote green and low-carbon development and promote the harmonious coexistence of man and nature.
How to reduce pollution and carbon emissions more effectively? The Management Committee of Taizhou Bay Economic and Technological Development Zone has implemented scientific and precise policies, increased project planning, and made every effort to promote the battle of environmental protection through a series of effective measures. Last year, four projects, namely the pollution reduction and carbon reduction project of Huahai Pharmaceutical South Sichuan Branch, the key technology of green synthesis of statins of Hongyuan Pharmaceutical, the carbon dioxide recovery and purification project of Haichang Gas, and the pollution and carbon reduction project of Tianyu Pharmaceutical, were selected as provincial pollution reduction and carbon reduction benchmarks.
A few days ago, the reporter walked into the South Sichuan Branch of Zhejiang Huahai Pharmaceutical Co., Ltd., and Taizhou Bay Economic and Technological Development Zone was selected as a national pilot ecological "password".
"Through nine measures, including solvent recovery, workshop equipment, freezing transformation, solid waste recycling, and lean management, we have comprehensively promoted the synergy of pollution reduction and carbon reduction of enterprises. Zhang Rongwei, director of safety and environmental protection of Huahai Pharmaceutical South Sichuan Branch, introduced that since 2020, the company has gradually implemented the implementation project of synergy in pollution reduction and carbon reduction, and the carbon emission per unit of output value has decreased from 0.93 tons/10,000 yuan in 2020 to 0.54 tons/10,000 yuan in 2022, a decrease of 41%.
Taking the company's solvent recovery workshop overall upgrading project as an example, the project carries out the overall transformation of the solvent recovery workshop, and sets up 36 distillation towers, 2 sets of inorganic permeation vaporization membranes, and 2 sets of double-effect distillation towers in the F01 and F02 solvent recovery workshops, involving the recovery of more than 10 kinds of various solvents, which can achieve economic benefits of 1.91 million yuan per year and reduce carbon dioxide emissions by 2,143 tons.
In order to reduce the risk of environmental pollution and consider the comprehensive utilization of waste salt, Huahai Pharmaceutical South Sichuan Branch built a new sodium bromide combined product production line in the W16 workshop, and the bromine-containing wastewater in the workshop was collected and treated separately at the front end, and the sodium bromide in the wastewater was recovered through the treatment processes such as scraper concentration, refining extraction, and drying, so as to achieve an annual output of 500 tons of sodium bromide products and an economic benefit of 13 million yuan per year. At the same time, through the improvement of equipment, the generation and dissipation of unorganized waste gas in the process of wastewater treatment are greatly improved.
In Zhejiang Haichang Gas Co., Ltd., the reporter learned that the company's annual output of 30,000 tons of carbon dioxide recovery and purification liquefaction benchmark project through the independent research and development of "variable temperature adsorption + VPSA low-pressure pressure swing adsorption + catalytic oxidation + low temperature distillation" technology, recovery of natural gas hydrogen production and methanol hydrogen production emissions CO_2. The energy consumption of this technology is about 50% lower than that of conventional pressure swing adsorption CO_2 recovery technology, the recovery rate reaches 95%, and the annual recovery CO_2 is about 30,000 tons, increasing the income by 4.5 million yuan per year.
While planning the project, promote the standardization of project management. To this end, the Taizhou Bay Economic and Technological Development Zone has issued the "Measures for the Management of Synergy in Pollution Reduction and Carbon Reduction in Medical and Chemical Parks", established an enterprise pollutant emission inventory and carbon emission inventory, and piloted the access standard for carbon intensity per unit of industrial added value of new reconstruction and expansion projects in 2023, so as to strengthen the evaluation of the effect of pollution reduction and carbon reduction of construction projects.
At the same time, the "Technical Guide for Pollution Reduction and Carbon Reduction in the Pharmaceutical and Chemical Industry" was compiled to sort out the path of pollution reduction and carbon reduction in the whole chain of the medical and chemical industry, and summarize the experience, practices and typical cases of the medical and chemical industry in the aspects of workshop demolition and reconstruction, equipment level improvement, green synthesis process application, waste resource utilization, etc., so as to provide important reference and reference for the pharmaceutical and chemical industry to carry out pollution reduction and carbon reduction construction.
