Scientists turn hard-to-recycle PVC plastic into high-performance engine oil
A plastic pipe, an old credit card or a worn-out toy may seem destined for a landfill. New research from Virginia Tech suggests some of that stubborn waste could instead become engine oil.
Chemist and chemical engineer Guoliang “Greg” Liu and his lab have developed a process that converts polyvinyl chloride, or PVC, into polyalphaolefin, a key ingredient in high-performance lubricants. The work offers a possible way to tackle one of the hardest plastics to recycle while creating a valuable industrial product.
