Yuxi High-tech Zone has solidly promoted green and low-carbon transformation and development and successfully entered the list of the first batch of zero-carbon parks created in Yunnan Province
In recent years, Yuxi National High-tech Industrial Development Zone in Yunnan Province (hereinafter referred to as Yuxi High-tech Zone) has explored and innovated based on actual conditions, adhered to the "zero-carbon" thinking, highlighted green empowerment, and solidly promoted green and low-carbon transformation and development, and achieved remarkable results.
Yuxi High-tech Zone has accelerated the cultivation of an all-green industrial system with three leading industries: cigarettes and supporting materials, biomedicine, and new energy batteries as advantageous industries, built an online monitoring system for "Diankewei" energy and carbon emissions, and established the province's first low-carbon service center and created a zero-carbon industry-university-research base. In 2022, the energy consumption per unit of industrial added value of the High-tech Zone will be only 0.070 tons of standard coal/10,000 yuan, and the carbon emission intensity will be only 0.119 tons of carbon dioxide/10,000 yuan, far better than the national and provincial average. It has successively won the title of "National Green Park","National Industry-City Integration Demonstration Zone","Yunnan Province Green and Low-Carbon Demonstration Industrial Park" and other titles. In May 2024, Yuxi High-tech Zone will be on the list of the first batch of zero-carbon parks created in Yunnan Province.
Strengthen scientific and technological leadership, 17 enterprises put into operation VOCs management facilities
Yuxi High-tech Zone insists on encouraging enterprises to use their own advantages to carry out green technology development and application, providing endogenous impetus for the district's green development and industrial green transformation.
Enterprises such as Jiankun Biotech and Maoduoli in the park lead the green development of the industry through resource recycling technology; Hongta Group conducts in-depth research on tobacco tar reduction and harm reduction technologies to empower the green upgrading of the cigarette industry; Zhonghui Power uses industrial Internet thinking and relies on big data technology to independently develop an intelligent power distribution operation and maintenance service platform, and builds a digital model of "condition monitoring + energy consumption analysis" and an "online + offline" service model. The platform has become a provincial-level service-oriented manufacturing demonstration platform, setting a new benchmark for the application of digital energy management technology.
In 2020, Yuxi Global Color Printing Paper Box Co., Ltd. took the lead in becoming the first batch of key volatile organic compound management enterprises in Yuxi City. After in-depth investigation of cutting-edge management technologies, it adopted the market mainstream and relatively mature technology "zeolite runner + regenerative combustion + activated carbon adsorption and desorption" method for special treatment, and the VOCs emission concentration was controlled within 30mg/m³, reaching the domestic leading level. In 2024, the acceptance of the VOCs exhaust gas online monitoring system was completed and connected with provincial platforms, achieving good economic and social benefits for the company.
At present, 17 enterprises in Yuxi High-tech Zone have completed and operated VOCs management facilities, which has promoted the continuous improvement of the ecological environment in the jurisdiction.
Pay close attention to reducing consumption and increasing efficiency, and build 4 national-level green factories
In promoting green and low-carbon development, Yuxi High-tech Zone insists on improving the inherent "green content" of enterprises as the top priority in building a green factory, and has made special efforts to guide and help enterprises maximize the use of clean and renewable energy.
Hongta Group Yuxi Cigarette Factory has started the transformation of coal-fired boilers since November 2020, using natural gas boilers to reduce production energy consumption. Currently, 7 natural gas boilers have been put into use, reducing pollutant emissions and reducing coal consumption. So far, Yuxi High-tech Zone has eliminated a total of 15 coal-fired boilers with boilers of 10 tons and below. In December 2021, the new reclaimed water station in the power workshop of Yuxi Cigarette Factory of Hongta Group was officially opened. The new reclaimed water station in the power workshop adopts integrated biochemical reaction sewage treatment technology, which innovatively integrates multiple traditional wastewater treatment processes. After the transformation, the sewage treatment volume reaches 120m³/h, which improves efficiency and greatly reduces the floor area. The treated reclaimed water reaches the national greening water standard and is all reused for greening of the factory, realizing the recycling of water resources. This marks a further improvement in the level of pollution prevention and environmental protection work at Yuxi Cigarette Factory.
At present, Yuxi High-tech Zone has four national-level green factories: Enjie New Materials, Xuri Plastics, Zhonghui Power, and Nanbao Biological.
Adhere to first trial and strive to promote the creation of zero-carbon parks
In recent years, Yuxi High-tech Zone has assessed the situation, seized the development opportunities of carbon peaking and carbon neutrality green industries, gave full play to its role as the "main battlefield" of energy conservation and carbon reduction, and strived to promote the creation of a "zero-carbon park" to take new steps.
In April 2024, Yuxi High-tech Zone entrusted the Carbon Neutralization Innovation Center of Yunnan University to prepare the "Implementation Plan for the Construction of Yuxi City High-tech Zone Zero Carbon Park"(hereinafter referred to as the "Plan"). The "Plan" carries out full research and analysis on the energy resource consumption, carbon dioxide emissions and green and low-carbon development foundation of the High-tech Zone, scientifically calculates the carbon peak and carbon neutrality time, reasonably determines the overall goal of zero-carbon park construction, systematically plans key tasks and implementation paths, and proposes a series of measures and key projects such as optimizing industrial structure and energy structure, improving energy resource utilization efficiency, and enhancing green development capabilities. At the same time, we adhere to the concept of two mountains, scientifically plan green development and coordinate park spatial planning, promote green upgrading of pillar industries, and achieve remarkable results in greening and low-carbon industrial structure.
The "Plan" proposes that by 2025, 40 key construction projects will be planned around the goal of zero-carbon parks, including 16 key projects for energy conservation and carbon reduction, and 24 key projects for quality improvement and efficiency improvement. We will continue to strengthen green technology research and development and promote new technologies and models, accelerate the development and application of new technologies and new models, accelerate the cultivation of green technology innovation entities and green technology achievements, and actively promote the transfer and transformation of green and low-carbon technology achievements with advanced technology, obvious results, high feasibility, and strong popularization. Strive to achieve that by 2025, the added value of green industries in the park will account for more than 90% of the park's industrial added value, add 3 national-level green factories and 2 provincial-level green factories, and fully build zero-carbon factories for enterprises above designated size. Completed more than 4 low-carbon product certifications or product carbon footprint evaluations; completed more than 2 independently developed carbon emission reduction projects to assist the high-end, intelligent and green development of the park, promote the zero-carbon process of the park, promote the construction of zero-carbon parks, and achieve The unity of economic benefits and environmental benefits.
In the next step, Yuxi High-tech Zone will make every effort to try first, tap potential and innovate to promote the implementation of the goals and tasks specified in the Plan to achieve results, continue to inject new impetus into the park's economic development, further improve the park's comprehensive competitiveness, and promote the park with high standards and high quality. Development in a green, low-carbon and sustainable direction.
