公斤级放大实验推进工业化应用
Phys.org报道了一项突破性催化剂技术:新型催化剂可在单步化学反应中直接处理混合塑料废弃物,无需预先分拣。该催化剂对聚烯烃(PE/PP)和聚酯(PET)等多种常见塑料均表现出高活性,可将其同步转化为有价值的化学原料(如芳烃和烯烃)。技术原理基于双功能催化位点:酸性位点催化聚合物链断裂,金属位点催化后续重整反应。相比传统分拣-单一塑料回收路线,该技术可大幅降低预处理成本,尤其适用于当前回收难度最大的混合塑料包装废弃物。研究团队正在推进公斤级放大实验,为工业化应用奠定基础。

国家邮政局:推进邮政领域禁限塑政策落实——对十四届全国人大四次会议第1275号建议的答复
国家邮政局经商市场监管总局,正式答复全国人大代表关于推进邮政领域禁限塑政策落实的建议。文件披露:十四五期间全行业塑料包装袋厚度减量50%、塑料胶带减量25%;2022年底北京、上海、江苏、浙江、福建、广东及海南率先实现禁塑目标;2025年将快递禁限塑纳入《快递暂行条例》;中国邮政在8省42地市投放生物降解竹快递袋;邮政、京东、顺丰、韵达在20余城市试点快递循环包装;快递包装绿色产品认证已颁发291张证书;全行业包装标准化率达86%。下一步将制定以竹代塑指导意见、扩大禁塑产品范围(含发泡保温箱、气泡袋等)、强化执法稽查和溯源认证体系。
塑料循环经济中,化工可以做什么?
本文以南京盛庆和化工的行业视角,系统阐述化工行业在塑料循环经济中的角色与路径。文章指出中国塑料消费量占全球15%,但2020年废塑料回收率仅23.09%,循环利用任重道远。核心讨论了机械回收与化学回收两种技术的优劣:机械回收成本高、分拣难、产品降级利用;化学回收可将废塑料拆分为单体实现闭环,但技术尚不成熟、经济性待验证。文章以赢创(Evonik)为例,展示了化工助剂(表面活性剂、消泡剂、润湿剂、VESTOPLAST®相容剂等)在提升机械回收效率与再生料性能方面的关键作用,以及甲醇醇解化学回收PET的研发进展。结论强调:发展塑料循环经济需要技术突破、产业链全生命周期合作、政策引导与消费者意识提高的四方协同。
塑料化学回收连获重大突破,国内产业化在即,全新万亿级风口正在到来!_裂解_技术_循环
塑料化学回收技术在中国取得了重大突破,特别是在生物酶解聚PET再生工业化装置和混合废塑料深度催化裂解(CPDCC)技术方面。这些技术不仅能耗低、碳排放少,还能处理各种低价值的PET废弃物,实现了从废弃端到原料端的闭环循环。万凯新材与Carbios的合作项目标志着全球首套年产5万吨的生物酶解聚PET再生工业化装置的诞生,而惠城环保则通过其CPDCC技术,为废塑料的化学循环提供了新的解决方案。这些进展预示着塑料化学回收产业即将迎来一个全新的万亿级市场。
