Scientists turn one of the hardest plastics to recycle into high-performance engine lubricant
Researchers at Virginia Tech have developed a chemical process to convert polyvinyl chloride (PVC) plastic waste into polyalphaolefin, a high-performance lubricant used in engine oil. This method offers a sustainable solution for recycling difficult-to-process plastics while producing valuable industrial materials.
Why it matters
This innovation addresses the dual environmental challenges of plastic pollution and the resource-intensive production of industrial lubricants.
Virginia Tech chemist and chemical engineer Guoliang "Greg" Liu and his research team have developed a method for transforming polyvinyl chloride (PVC) into polyalphaolefin, an important ingredient used in lubricants including engine oil.
Published Aug. 5 in Nature , the work could offer a way to address two separate environmental problems at once: the difficulty of recycling PVC and the need to produce valuable industrial lubricants more sustainably.
PVC is especially challenging to recycle because it contains chlorine and can include a wide range of additives depending on how it was manufactured. Those complications mean large quantities of PVC ultimately end up in landfills.
Meanwhile, demand continues to grow for lubricants such as engine oil, which can carry a significant environmental cost to produce. Converting discarded PVC into a useful lubricant component could therefore reduce plastic waste while creating a valuable new product.
