Recently, the first public announcement was made regarding the update to the environmental impact assessment for Dongjing Bio-Environmental Protection Technology’s project aimed at producing 200,000 tons of 1,4-butanediol per year. The changes include an increase in the capacity of the formaldehyde production unit from 2×240,000 t/a to 2×300,000 t/a; meanwhile, the hydrogen production capacity using calcium carbide waste gas was changed from 18,000 Nm3/h to 20,000 Nm3/h using natural gas. Change to the project of Inner Mongolia Dongjing Bio-Environmental Protection Technology Co., Ltd. for the annual production of 200,000 tons of 1,4-butanediol. Nature of the change: Modification. Location of construction: The vacant land reserved by Inner Mongolia Dongyuan Technology Co., Ltd. in Wuda Industrial Park, Wuhai Economic Development Zone. Changes: The capacity of the formaldehyde production facility has been changed from 2×240,000 t/a to 2×300,000 t/a; the hydrogen production system using carbide off-gases has been adjusted from 18,000 Nm3/h to one that uses natural gas, with a capacity of 20,000 Nm3/h. On May 20, 2021, the groundbreaking ceremony for Inner Mongolia Dongjing Bio-Environmental Protection Technology Co., Ltd.’s project to produce 200,000 tons of BDO per year was held on the premises of Inner Mongolia Dongyuan Technology Co., Ltd., marking the official start of construction for this project. The project is located to the north of the first phase of Dongyuan Technology in Inner Mongolia, covering an area of about 150,000 square meters (225 mu). The total investment in the project amounts to 29.4 billion yuan, with completion and operation planned for 2022. The project utilizes **Guanda technology, and takes advantage of local resources such as lime, electricity, and coal to establish an integrated circular economy industry development model based on 1,4-butanediol (BDO) as the key component. Once completed, the maximum production capacity of Dongyuan Technology’s BDo will reach 400,000 tons.
