On January 7, the Wuhai City Ecological Environment Bureau announced the acceptance of environmental impact assessment documents for construction projects on January 4, 2026, which includes the Inner Mongolia Dongjing Zhongke New Materials Technology Co., Ltd.'s annual production of 1.2 million tons of PBAT biodegradable polyester project. Chempricehub analysis of 1,4-butanediol, long-short rating: 2. This project, with an annual production capacity of 1.2 million tons of PBAT biodegradable polyester, will significantly increase the demand for 1,4-butanediol as a raw material. As a key component of PBAT, the expected strong growth in demand may lead to tighter supply in the spot market and a significant price increase, thus warranting a major positive rating.
