Waste plastic treatment technology is becoming an increasingly more important concern in the recovery of valuable fossil fuel resources and especially in terms of environmental protection. This is particularly relevant in the case of halogenated plastics, such as PVC, where the presence of chlorine renders the waste less amenable to recycle than is the case with such polymers as polyethylene or polypropylene. Tens of millions of tons of PVC are manufactured each year in the US and practically none of it is recycled. Catalytic hydrodehalogenation represents an alternative, innovative and promising approach whereby the waste halogenated plastics can be transformed into reusable products. This investigation explores the feasibility of a catalytic degradation of waste PVC with a concomitant targeted chemical transformation of the chlorinated content into recoverable HCl. This will generate a fuel oil free of any chlorinated contaminants, which can be combusted without the problem of releasing toxic chlorine compounds into the environment. The proposal represents a significant advance over the investigators prior successful efforts in fundamental hydrodehalogenation studies. The research will also be a part of a multidisciplinary training program that provides research experiences for undergraduates, undergraduate co-op students, and graduate students and that targets underrepresented groups. A major long-term societal benefit would also be the development of a new remediation technology in which a potentially toxic waste is transformed into commercially viable products with no detrimental effect on the environment.

废塑料处理技术在回收宝贵的化石燃料资源，特别是在环境保护方面越来越受到人们的关注。这在卤化塑料，如聚氯乙烯的情况下尤其重要，因为氯的存在使废物比聚乙烯或聚丙烯等聚合物更不容易回收。美国每年生产数千万吨聚氯乙烯，几乎没有一件被回收利用。催化加氢脱卤是一种替代的、创新的和有前途的方法，通过这种方法，废弃的卤化塑料可以转化为可重复使用的产品。本研究探讨了催化降解废PVC的可行性，同时有针对性地将氯化内容转化为可回收的HCl。这将产生一种不含任何氯化污染物的燃料油，它可以燃烧，而不会向环境中释放有毒的氯化合物。该建议代表了一个重大的进步，比研究人员之前的成功努力，在基础的氢卤化研究。这项研究也将成为一个多学科培训项目的一部分，该项目为本科生、本科合作学生和研究生提供研究经验，并针对代表性不足的群体。一项重大的长期社会效益还将是发展一种新的补救技术，在这种技术中，可能有毒的废物被转化为商业上可行的产品，对环境没有有害影响。
