产能潮来袭！又一3万吨生物法丙二醇（PDO）项目公示

Core Viewpoint - The article discusses the significant transition of China's bio-based 1,3-propanediol (PDO) industry from "technology validation" to "scale production" by 2025, highlighting the increasing demand for green transformation in downstream markets such as textiles and cosmetics [4][6]. Group 1: Industry Development - By 2025, multiple companies are advancing the construction of large-scale production bases for bio-based PDO, with the recent environmental assessment announcement for Yifeng Jiatai's 30,000 tons/year PDO project marking the fourth such project in China [4][6]. - Domestic companies like Dongfang Shenghong, Qingda Zhixing, and Juhua Co. have increased R&D investments to achieve bio-fermentation production of PDO, breaking the technological monopoly of foreign firms [7][8]. Group 2: Technological Innovations - Qingda Zhixing is noted for mastering both glycerol and sugar fermentation technologies for PDO production, with established production bases in Shandong and Shanxi [8]. - Hengcarbon Technology has developed a revolutionary third-generation PDO production technology with minimal environmental impact, achieving a production capacity of 15,000 tons/year [8]. - The next phase of bio-based PDO production will focus on "multi-raw material" technology to reduce cost risks [9]. Group 3: Market Expansion - PDO is widely applicable in various industries, including polyester, cosmetics, polyurethane, pharmaceuticals, and coatings [11]. - The global bio-based PTT market, which utilizes PDO as a core monomer, is projected to grow from approximately 3.4 billion yuan in 2023 to 8.3 billion yuan by 2030, with a compound annual growth rate of 13.1% [14]. - Companies like Qingda Zhixing and Dongfang Shenghong are forming strategic partnerships to create integrated industrial bases for bio-based materials, ensuring competitive advantages in the market [15][16].
