**Progress on the Construction of the 50,000-ton/year Polyglycolic Acid Demonstration Project at Energy Shaanxi Yulin Chemical Industry – Author/Source: Energy Knowledge Base; Date: February 27, 2022; Clicks: 13. At 8:30 on February 21, the “100-Day Campaign” for the construction of this project, which is supervised by Luohua Group Company and known as the 50,000-ton/year Polyglycolic Acid Demonstration Project in Energy Shaanxi Yulin Chemical Industry (hereinafter referred to as the “GYPGA” project), was launched. This “100-Day Campaign” marks the entry of the GYPGA project into a critical final phase. The 50,000 tons per year polyglycolic acid (PGA) demonstration project is implemented in line with the **Energy Group’s initiative to promote recyclable, recoverable, and biodegradable alternative products**, as well as in response to policies aimed at restricting the use of non-biodegradable plastic products. It constitutes a **level demonstration project and is also part of the expansion of the coal-based olefins industry chain**. Once put into production, it will mark a breakthrough for our country in the field of biodegradable plastics (PGA). The project is located in the Qingshui Industrial Park in Dabaochang Town, Shenmu City, Yulin City, Shaanxi Province, covering an area of 9.8 hectares. It utilizes technology provided by Shanghai Pujing Chemical Engineering and represents the world’s first polyglycolic acid production facility. With a total investment of around 1 billion yuan, it is a model project of ** level and part of the extension project for the coal-to-olefins industry chain. The polyglycolic acid produced has good biodegradability and biocompatibility, high mechanical strength, excellent formability, and superior gas barrier properties; it can be used in packaging materials, surgical sutures, and other applications. Once the project is put into operation, it will mark a breakthrough of zero in the production of biodegradable plastic products in our country. Construction contents: include a refining unit, a prepolymerization unit, a pyrolysis and cyclization unit, a purification unit, a solvent recovery unit, a final polymerization and molding unit, a packaging unit, as well as supporting facilities such as a refrigeration station, a heat transfer oil station, a plant substation, cabinet rooms, plant-wide systems, and a circulating water station (renovated).
