The first phase of Sinopec’s 500,000 tons per year polylactic acid project commenced construction in Zhijin, Guizhou

Uses and synthesis methods of polyglycolic acid; properties. Polyglycolic acid is a crystalline polymer with a crystallinity of 46–52%, a density of 1.5–1.64 g/cm3, a glass transition temperature of around 36°C, and a melting point of approximately 224°C. Polyglycolic acid with high molecular weight exhibits good mechanical properties. Since polyglycolic acid is a dense crystalline polymer, it is practically insoluble in all organic solvents except hexafluoroisopropanol. Polyglycolic acid (PGA) is utilized in various fields such as tissue engineering scaffolds, drug release carriers, and barrier materials, owing to its excellent mechanical properties and biodegradability. Performance: Polyglycolic acid is a thermoplastic linear polyglycolic acid with certain processability; it can be extruded, injected, spun, and blown using standard equipment. Polyglycolic acid is a synthetic polymer material with excellent biodegradability and biocompatibility. Unlike traditional polymer materials with stable properties such as plastics and rubbers, polyglycolic acid gradually degrades over time after being used as a material, eventually turning into water and nitrogen that are harmless to humans, animals, plants, and the natural environment. The applications of polyglycolic acid are mainly seen in the fields of biomedicine and ecology. Synthesis & Industrial Production: The synthesis of PGA typically employs a two-step ring-opening method, in which glycolic acid is first converted into lactide, and then lactide is ring-opened to produce PGA. Another reported method is the melt/solid-state polycondensation approach, whereby oligomers are first prepared in a molten state, and these oligomers are then crushed to carry out solid-state polycondensation; this method allows for the production of PGA with a high relative molecular weight. The original raw material for polyglycolic acid is glycolic acid, which is widely found in nature, especially in sugarcane, beets, and unripe grape juice. Due to the difficulty in separating and purifying it, it is currently obtained industrially through organic synthesis methods.

From April 2008, when Cao Xianghong, an academician of the Chinese Academy of Engineering and chief engineer of Sinopec Group, led a team to Zijin for an inspection, to February 7, 2017, when the Ministry of Environmental Protection issued the approval document titled \"Approval on the Environmental Impact Assessment Report for Sinopec Great Wall Energy Chemical (Guizhou) Co., Ltd.’s 600,000 tons per year polyolefin project\" under document number Huan Shen [2017] No. 22, the Sinopec Zijin coal chemical project, after nearly 10 years, finally received good news. It is expected that it will receive approval from the Guizhou Provincial Development and Reform Commission in the first half of this year (2017), after which construction can begin in earnest. In the image, Sinopec’s Zhijin coal chemical project is the industrial project with the largest investment in Guizhou’s industrial history. The planned investment amounts to 52 billion yuan. The construction scope includes a phase 1 project for producing polyolefins from coal at a capacity of 600,000 tons per year, as well as a phase 2 project for producing coal gas at a capacity of 4 billion cubic meters per year. Additionally, 2×350,000 kilowatt cogeneration plants and a coal raw material base with a capacity of 20 million tons per year will be built as part of this project. Throughout the progress of this project, various levels of government and departments have consistently worked hard to promote it. The staff and workers in the Bijie Pilot Zone have pooled their wisdom and efforts, working together as one team; many people have contributed their part to ensuring that this project is implemented as soon as possible and that construction can begin at an early date. Especially in the Zijin Economic Development Zone in Guizhou, where the project is located, all the staff and workers have been busy with the preliminary work for this project for many years. Traveling to other provinces and even to Beijing, as well as making repeated visits to various government departments, have become commonplace. They submit reports to various parties and coordinate efforts everywhere; everyone is demonstrating a spirit of perseverance, staying committed and fighting hard without giving up. The first phase of the 600,000 tons per year coal-based polyolefin project was one of the major projects planned under the Strategic Cooperation Framework Agreement signed in October 2010 between the People’s Government of Guizhou Province and Sinopec. In February 2013, the National Development and Reform Commission approved the initiation of preliminary work for this project. In June 2015, the same commission approved it as one of the 9 national demonstration projects for the olefin industry. Both Document No. 2 issued by the State Council in 2012 and Document No. 35 issued by the General Office of the State Council in 2013 listed this project as a key industrial project to support the development of the Bijie Pilot Zone. “The approval process for major projects is extremely complex, and the approval of the environmental impact assessment report is the most important and difficult part. The environmental impact assessment report for this project is so large that it requires several large cardboard boxes to hold it, and several people are needed to carry it. ”Wang Xingming, deputy director of the Zhijin Economic Development Zone, explained. In accordance with the approval procedures for construction projects, the requirements for project approval include dozens of items such as the planning and site selection opinion letter, pre-examination of land use, environmental impact assessment report, water resources assessment report, soil and water conservation plan, assessment report on the establishment of sewage discharge outlets into rivers, social stability risk assessment report, energy efficiency assessment report, etc. At present, all these requirements have been approved by the relevant functional departments at the ** provincial and municipal levels. Among them, the approval of the project’s environmental impact assessment report is the most crucial supporting element for the project to be approved. From November 27 to 28, 2015, the Environmental Engineering Assessment Center of the Ministry of Environmental Protection organized experts in Guiyang to conduct the first review of the environmental impact assessment report for the olefin project. The experts present offered many suggestions for revisions to sections related to air quality, groundwater, wastewater treatment, and safety and health protection distances. On March 1, 2016, the **Ministry of Environmental Protection decided not to approve the first draft of the environmental impact assessment report. After the first review meeting for the environmental impact assessment report, and with the close attention of the relevant ministries and provincial and municipal leaders, the relevant departments in Bijie City, adhering to the principle of giving equal importance to development and ecology, held multiple consultations with the project owner, relevant departments, and the entities responsible for preparing the report. Based on the first draft of the environmental impact assessment report and after thorough analysis, additional tests and surveys were conducted regarding various environmental factors identified by experts, such as those related to air quality, groundwater, wastewater treatment, and safety and health protection; these additional tests and surveys alone cost over 10 million yuan ； The wording in the relevant sections was revised word for word, and the project environmental impact assessment report was supplemented and improved to ensure the scientific validity, relevance, and practicality of the second version of the report. The environmental impact assessment report was finalized in October 2016 and submitted to the Ministry of Environmental Protection for approval. From November 9 to 10, 2016, the Environmental Engineering Assessment Center of the Ministry of Environmental Protection once again organized experts in Beijing to review the environmental impact assessment report. At the review meeting, the experts present gave full approval to the report and unanimously approved its review and validation. On February 7, 2017, the environmental impact assessment report was finally approved by the **Ministry of Environmental Protection. “Since the 12th Five-Year Plan period, in line with the overarching theme of \"accelerating development, speeding up transformation, and achieving leapfrog progress\" as well as the strategic goal of building a strong industrial province put forward by the Guizhou Provincial Party Committee and the provincial government, all departments at all levels in the city have made promoting industrial development the top priority of their economic efforts. The approval granted by the Ministry of Environmental Protection for the environmental impact assessment report of this project signifies that the project is about to enter the phase of actual construction, and it also indicates that Bijie City’s strategy of building a strong industrial city through large-scale project development can be further advanced. “After the approval of the environmental impact assessment report, we promptly coordinated with Sinopec Great Wall Energy Chemical (Guizhou) Company and Shuikuang Group to resolve promptly the issue of coal resource allocation for the olefin project, thereby ensuring a supply of coal resources for Sinopec’s commencement of construction and future operations ； Second, actively coordinate with the Provincial Development and Reform Commission to approve the project, thereby providing the legal procedures and basis for Sinopec to commence construction ； Third, actively coordinate with Sinopec Great Wall Energy Chemical (Guizhou) Company to accelerate related tasks such as engineering design, bidding, and equipment procurement, so as to make full preparations for the commencement of construction ； Fourth, accelerate the construction of infrastructure such as road networks, power supply, and water supply on a comprehensive basis, to provide support for project development in terms of heavy freight transportation, electricity, and water supply for production and daily life ； Fifth, investment promotion efforts should be focused on downstream products of olefins in order to extend the coal chemical industry chain and increase the value of olefin products locally. ”That’s what Pan Fayong, the head of Zhijin County, said. It is reported that once the first phase of the olefin project is fully completed and put into operation, it will generate an annual output value of around 10 billion yuan, as well as annual tax revenues of over 1.5 billion yuan. It will also create employment for more than 30,000 people and help 83,000 people escape poverty. The full-scale development of Sinopec’s Zijin coal chemical project will undoubtedly play a positive role in accelerating the in-depth exploitation of the advantageous resources in the Bijie Pilot Area and promoting the adjustment and upgrading of the industrial structure ； It holds significant exemplary and guiding value for the Bijie Pilot Zone in fulfilling its mission related to the \"two new initiatives\" and in striving to create an upgraded version of reform and development; it is also crucial for successfully overcoming the \"113 challenges\", achieving poverty alleviation on schedule, and ensuring that comprehensive prosperity is attained by 2020 in line with the rest of the country.

The estimated technical approach is quite average. The polyglycolic acid project requires large investments, and its sales revenue is not high – so how good can its economic returns be?

It’s being implemented everywhere; given the context of cost reduction, project implementation is quite challenging.

Construction details: The planned 500,000 tons per year polylactic acid production facility will have an initial capacity of 200,000 tons per year, with construction to be completed in 2024； Phase 2 will bring the capacity for polyglycolic acid to 300,000 tons per year, with completion scheduled for 2026. The project includes a gas gasification unit, a gas cryogenic separation unit, coupling and hydrogenation units, and a polyglycolic acid production unit; it is also equipped with a cogeneration unit and an air separation unit. Total project investment: 2,376,767 million yuan, of which the total investment for Phase I is 1,233,160 million yuan, and the total investment for Phase II is 1,143,607 million yuan.

I wonder if this project has been affected by the energy assessment? ?
