近日，三大日本化工巨头在高分子循环回收再利用方面传来大动作。 【DT新材料】获悉，近日， 东粤化学20 万吨/年混合废塑料资源化综合利用示范性项目试生产成功，受到全球废塑料回收行业极大关注，刷屏内网。 之所以如此震动，是因为： （1）体量大。年废塑料处理量高达20万吨，实现了从"废塑料→循环化工原料→循环高端材料"的绿色化工产业链条，并且可复制推广，号称 全球首套和 首创。 （2）收率高。项目采用"一步法"深度催化裂解技术（CPDCC），可将废塑料直接转为裂解气、液化气、轻质油等，较传统的废塑料化学两步法（废塑料- 热解油-气）的收率大大提高。 先不评价项目本身，最重要因素应该是：高分子循环再利用，已经毫无疑问成为当下化工产业的"顶流"。 在国内，除东奥化学外，中石化、万华化学、航天石化、金发科技、英科再生、奇美实业、科茂环境、恒誉环保、佳人新材料、格林循环、海尔再循环等 也已经在纷纷布局。 在国外，热度也同样高，比如隔壁的日本。 之前分析过《日本化工巨头大"撤退"》，DT新材料报道过日本化工巨头第一个集体大动向是布局生物基化学品和材料，其投入力度还真不输走在前列的 欧洲化工巨头。而说到他们集体围观的第二个热 ...

Core Viewpoint - The successful trial production of Dongyue Chemical's 200,000 tons/year mixed waste plastic resource utilization project has garnered significant attention in the global waste plastic recycling industry, marking a notable advancement in the green chemical industry chain from waste plastic to high-end materials [1][2]. Group 1: Project Significance - The project has a large scale, processing 200,000 tons of waste plastic annually, establishing a replicable and innovative green chemical industry chain [2]. - The project utilizes a "one-step" deep catalytic cracking technology (CPDCC), significantly improving yield compared to traditional two-step methods [2]. Group 2: Industry Trends - High polymer recycling has become a leading trend in the chemical industry, with major companies in China, such as Sinopec and Wanhua Chemical, actively investing in this area [3][4]. - Internationally, Japanese chemical giants are also focusing on high polymer recycling, with significant investments in bio-based chemicals and materials [5][6]. Group 3: International Developments - Mitsubishi Chemical has completed a waste plastic chemical recycling facility in Japan, with an annual capacity of 20,000 tons, utilizing supercritical water chemical recycling technology [6]. - Other Japanese companies, such as Ube and Toray, are also making strides in recycling initiatives, including the recovery of nylon fibers from discarded fishing nets and the establishment of a committee for efficient dismantling of end-of-life vehicles [8][10]. Group 4: Technological Innovations - The article highlights the advancements in chemical recycling technologies, particularly the supercritical water thermal cracking method, which is noted for its high efficiency and lower carbon emissions compared to traditional pyrolysis methods [19]. - Major global players, including BASF and ExxonMobil, are also involved in high polymer recycling, indicating a broad industry shift towards sustainable practices [20].
