The National Science Foundation (NSF) awarded a $600,000 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to Virginia Polytechnic Institute & State University (Virginia Tech) for a project titled "CAS-SC: Tuning Hydrocarbon Products from Temperature-Gradient Thermolysis of Polyolefins and the Subsequent Upcycling to Functional Chemicals." The project aims to develop techniques for converting common plastic waste, such as polyethylene (PE) and polypropylene (PP), into high-value surfactants and other chemicals through a process of "cascade degradation and upcycling." The key products and services to be delivered include: 1) employing temperature-gradient thermolysis to degrade PE and PP into intermediate chemicals, 2) functionalizing the thermolysis products to produce amphiphilic surfactants, and 3) developing non-ionic surfactants from the thermolysis products. This project seeks to provide new approaches for recycling plastic waste into valuable materials while reducing energy consumption and carbon emissions. The award period runs from April 1, 2024 to March 31, 2028.
