Recently, Yifeng Jiatai (Mudanjiang) Biotechnology Development Co., Ltd. conducted the first environmental impact assessment (EIA) announcement for its batch-fed fermentation project to produce 30,000 tons/year of 1,3-propanediol (PDO). PriceSeek analysis of 1,3-propanediol, with a long-short score: -1.5. The project plans to produce 30,000 tons of 1,3-propanediol annually. The expansion of new production capacity will significantly increase market supply, potentially leading to oversupply and exerting downward pressure on spot prices. Considering the current market supply-demand situation, it is expected that short-term spot prices will face pressure, with bearish factors being relatively pronounced.
