This Project Grant from the National Science Foundation's Mathematical and Physical Sciences program provides $689,738 to Clemson University from August 2022 through July 2025 to research sustainable recycling methods for agricultural and plastic waste via organosulfur chemistry. Professor Rhett Smith and students will study reaction pathways between elemental sulfur and functional groups in waste plastics like polyethylene terephthalate and polycarbonates, as well as lignin, to facilitate...
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...
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...
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...
The National Science Foundation (NSF) Engineering program (CFDA 47.041) has awarded a $463,136 Project Grant to the University of Massachusetts Lowell to explore a hybrid approach to upcycling waste polyethylene (PE) into value-added chemicals. The two-step process involves oxidative catalytic pyrolysis to decompose PE into intermediate products, followed by bioconversion using engineered yeast to produce nylon precursors and other platform chemicals. The research aims to develop an economical...
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...
This $1,800,000 Project Grant awarded by the National Science Foundation Division of Chemistry under the Mathematical and Physical Sciences program (CFDA 47.049) supports the establishment of the NSF Center for Polymers for a Circular Economy (PCE). The center aims to develop new strategies for synthesizing effective replacement polymers from inexpensive and sustainable feedstocks like carbon dioxide, biomass residues, and food waste oils. Key objectives include designing novel polymers that can...
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...
This five-year, $444,267 Project Grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems will support research into developing an alternative approach to plastic conversion based on a catalytic plasma-mediated depolymerization process operating at ambient temperature and in liquid water. Funded under the NSF's Engineering program (CFDA 47.041), the grant aims to detail the mechanisms of plasma-assisted depolymerization of plastics...
This Project Grant from the National Science Foundation's $387,370 Engineering program (CFDA 47.041) funds research at Clemson University from October 1, 2021 to April 30, 2024 to develop dual function materials for capturing and converting carbon dioxide into methanol and higher alcohols. The grantee, Clemson University, will synthesize, characterize and evaluate materials capable of both capturing carbon dioxide and catalyzing its conversion to more valuable chemicals, with a focus on...
