强强联手！聚焦全球首个生物基尼龙6商业化

Core Insights - The article discusses the collaboration between Genomatica and Sojitz Corporation to commercialize bio-based nylon 6, aiming to provide a cost-competitive alternative to petroleum-based nylon 6 [4][5]. - The bio-based nylon 6 has already been produced from 100% renewable sources and is in the process of further commercial evaluation [4]. - China is highlighted as the largest producer and consumer of nylon 6, with a projected market size of approximately 43.088 billion yuan and a total capacity of about 7.25 million tons by 2024 [7]. Group 1: Industry Developments - Genomatica's proprietary technology converts renewable carbon (biomass sugars) into caprolactam, which is then polymerized to produce 100% renewable bio-based nylon 6 [9]. - The bio-based nylon 6 has been tested in downstream material development, collaborating with brands like lululemon, H&M, and Vaude [5]. - The sustainable development strategies of nylon 6 companies include replacing petroleum-based products with bio-based caprolactam and recycling waste fibers [8]. Group 2: Production Pathways - The primary pathway for bio-based caprolactam development involves fermenting glucose to produce lysine, which is then chemically converted to caprolactam [10]. - Other research teams are exploring more direct pathways to convert sugars or their derivatives into caprolactam [10]. - Current challenges in bio-based nylon 6 development include the sustainable production of its monomer caprolactam and the need for breakthroughs in related technologies [10]. Group 3: Market Outlook - The rising competition and increasing demand for sustainability in the nylon 6 market suggest a shift towards bio-based alternatives [8]. - Despite the current cost increases and weak demand for nylon 6, the long-term market trend indicates a growing interest in sustainable raw material substitutes [10].
