弗吉尼亚理工大学的研究人员开发了一种创新方法，可将聚氯乙烯（PVC）这类难以回收的塑料废料转化为高性能润滑油的关键成分聚阿尔法烯烃 1。该研究成果已发表在《自然》杂志上 1，为同时解决塑料回收难题和可持续生产润滑油两大环保问题提供了新的思路。
该团队的实验流程为：将PVC置于溶剂中，加入三氯化铝和阿尔法烯烃，随后加热至158华氏度，持续3小时 1。研究负责人Guoliang Liu表示："我们已经证明了用塑料废料制造高性能润滑油是可行的，这些润滑油是绿色的" 1。此项研究由Eric Munyaneza Nuwayo、Connor S. Thompson和Abby Civiello等团队成员共同完成 1，相关论文发表于《自然》杂志2026年第656卷第8127期 1。
Researchers at Virginia Tech have developed a process to transform polyvinyl chloride (PVC) plastic waste, one of the most difficult plastics to recycle, into a key component used in high-performance lubricating oils.1 The breakthrough, published in Nature on August 5, 2026, addresses two environmental challenges simultaneously: the disposal of PVC waste and the sustainable production of synthetic lubricants.1
The conversion method involves placing PVC in a solvent with aluminum trichloride and alpha-olefins, then heating the mixture to 158 degrees Fahrenheit for three hours.1 The process yields polyalphaolefins, which are essential components in premium engine lubricants.1 According to Guoliang Liu, a member of the research team, "We have demonstrated that it is feasible to manufacture high-performance lubricating oils from plastic waste, and these lubricating oils are green."1 The study was conducted by Liu alongside team members Eric Munyaneza Nuwayo, Connor S. Thompson, and Abby Civiello.1
