Group 1: Company Developments - Braskem celebrates the 15th anniversary of its bio-based polyethylene brand "I'm green™" and announces an increase in production capacity at its bio-ethylene plant in Triunfo, Brazil, from 260,000 tons to 275,000 tons [1]. - Since the launch of its bio-based PE in 2010, Braskem has produced over 1.2 million tons of bio-based PE and has invested $87 million to expand its bio-ethylene plant capacity from 200,000 tons to 260,000 tons in 2023 [2]. - Sinopec has successfully launched its first bio-based polyolefin product in China, with an initial production of 2,500 tons from its bio-based polyolefin project that started in October 2023 [3]. Group 2: Industry Trends - Bio-based ethylene is becoming a focal point for major chemical companies like Braskem, BASF, and New Energy Blue, driven by the trend towards low-carbon sustainability [2]. - The synthesis technology routes for bio-based ethylene include fermentation, thermochemical conversion, enzymatic catalysis, and microbial synthesis, with various companies employing different methods [4]. - The price of bio-ethanol, primarily produced from non-food biomass, is crucial for the competitiveness of bio-based ethylene in the domestic market, with estimates suggesting a target price of 4,000 yuan per ton or lower [5]. Group 3: Technological Insights - The main synthesis route for bio-based ethylene is ethanol dehydration, which is influenced by the cost of bio-ethanol [5]. - Different technological routes for bio-based ethylene production have varying levels of maturity and advantages, such as sugar fermentation being highly mature but reliant on food crops, while cellulose fermentation shows potential for reduced resource competition [6].
