This Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences (CFDA 47.049) program will provide $590,484 to Clemson University to investigate a new method for converting agricultural and plastic waste into useful materials through a process called "thiocracking." The key products and services to be delivered include: Developing a two-step thiocracking-desulfurization sequence to break down complex waste streams, including plastics,...
This Project Grant from the National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems provides $270,526 to Clemson University under the Engineering program (CFDA 47.041) to develop controlled fragmentation of polyolefinic materials triggered by microwave irradiation. The university will design materials with properties of conventional polyolefins but capable of controlled deconstruction into macromolecular chain fragments for reuse. Researchers will...
The University of Southern California will receive $539,543 from the National Science Foundation Division of Chemistry under the Mathematical and Physical Sciences federal grant program (CFDA 47.049) to develop environmentally friendly methods for recycling polyvinyl chloride (PVC) plastic waste. Drs. Megan Fieser and Shaama Mallikarjun Sharada will lead efforts to selectively dechlorinate or dehydrochlorinate PVC using homogeneous catalytic processes, with the goal of transforming PVC into...
This Project Grant award, funded by the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049), aims to advance the fundamental understanding of sustainable chemical processes for plastic waste deconstruction and upcycling. The $100,000 award, granted on February 1, 2025, supports research at the University of California, Irvine to uncover the molecular mechanisms underlying the hydrogenolysis of polyethylene, the world's most common plastic. The goal is...
This Project Grant award of $118,229 from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports the development of novel sustainable polymers that can be easily recycled. The goal is to design chemically recyclable polyolefin materials with tunable properties that can be reverted to their monomers under mild conditions, reducing the energy-intensive depolymerization process common for most commodity polymers. The 5-year project, starting on...
This $465,000 National Science Foundation project grant will support the development of an upcycling strategy for polyvinyl chloride (PVC) plastic waste through chemical transformations producing value-added products. Funded under the Mathematical and Physical Sciences program (CFDA 47.049), Professor Rebecca Braslau of the University of California, Santa Cruz will work to convert PVC into 1,5-hexadiene and other alkane products using mild temperatures and ambient pressure. These efforts aim...
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...
This National Science Foundation (NSF) Project Grant, awarded under the Engineering program (CFDA 47.041), will fund research to develop a novel biocatalytic process for deconstructing and recycling polyethylene terephthalate (PET) plastics. The $378,682 award to the University of Colorado aims to explore the use of natural enzymes, such as lipases, to break down PET in nonaqueous solvents rather than water, which can improve the efficiency and conversion of plastic waste. The research will...
Through this $699,254 Project Grant awarded by the National Science Foundation's Division of Chemistry under the Mathematical and Physical Sciences program (CFDA 47.049), Professor Eugene Y. Chen of Colorado State University is developing new synthetic routes for the construction of technologically important cyclic polymers and copolymers from bio-based renewable monomers. The project aims to precisely control the structures and sequences of these cyclic polymers and copolymers using Lewis...
This $555,000 Project Grant award from the National Science Foundation's Mathematical and Physical Sciences (CFDA 47.049) program will support Professor Stephen A. Miller of the University of Florida in converting post-consumer plastic waste and bio-based feedstocks into a novel family of sustainable polymers. The key objectives are to: 1) optimize the depolymerization of polyesters, nylons, and other commodity polymers via aminolysis; 2) optimize the Amide to Ester Polymerization (ATEP) process...
