赢创将优化蛋氨酸全球生产布局！中国生物法关键技术已突破！

Core Viewpoint - Evonik announced plans to optimize the global production layout of MetAMINO® (DL-methionine) in the third and fourth quarters of 2025, including temporary shutdowns of production facilities in Singapore and Antwerp to enhance energy efficiency and reduce CO2 emissions [1][4]. Group 1: Production Capacity and Market Dynamics - The global methionine production capacity is projected to reach 2.35 million tons per year by 2024, with Evonik, Adisseo, and Sinochem accounting for 71% of this capacity [4]. - China's methionine production capacity is expected to reach 840,000 tons per year by the end of 2024, representing 36% of the global total, with further expansion anticipated to exceed 1.2 million tons by 2029 [5][6]. - China has transitioned from a net importer to a net exporter of methionine, with a projected consumption of 430,000 tons in 2024, including 160,000 tons imported and 410,000 tons exported, resulting in a net export of 250,000 tons [6]. Group 2: Production Methods and Innovations - Biotechnological methods for producing methionine offer advantages over chemical methods, including higher efficiency and reduced safety risks associated with toxic substances [7]. - The industrialization of biological methionine production has been slow due to low yield during fermentation processes, with only one company, HJ, successfully achieving bulk production [9]. - In China, significant advancements in L-methionine biosynthesis have been made by academic teams, leading to the development of microbial cell factories for efficient precursor synthesis [11][12].
