LSU researchers have created a new, low-cost way to break down plastic, a potential\u00a0breakthrough that could save billions of dollars and eliminate billions of tons of plastic pollution.<\/strong><\/p>\n\n\n\n

\n

\u201cGetting plastics to the recycling plant is only half the battle. The other half is reusing that plastic waste to create new products,\u201d said James Dorman, program manger with the U.S. Department of Energy and former LSU Chemical Engineering professor. \u201cSome estimates show as much as 95 percent of plastics in the U.S. ends up in landfills and incinerators. Our process breaks down commercial plastics, including polystyrene and high- and low-density polyethylene, so recycled material can be seamlessly integrated into new products.\u201d<\/strong><\/p>\n<\/blockquote>\n\n\n

Dorman and LSU Chemical Engineering Professor Kerry Dooley use electromagnetic induction heating along with special magnetic materials and catalysts to break down different types of plastic.<\/p>\n\n\n\n

Electromagnetic waves melt the plastics from the inside out, which requires far less energy. Dorman and Dooley\u2019s process also produces only small amounts of unwanted byproducts such as methane, a powerful greenhouse gas, unlike conventional recycling. The conventional method of melting plastic waste, pyrolysis, requires high temperatures and produces gases like carbon dioxide and hydrogen.<\/p>\n\n\n\n

Dorman and Dooley\u2019s method works at lower temperatures and offers more precise control of the breakdown process. Their method can be tailored to handle food residues and other contaminants that help limit plastics recycling. For example, recyclers commonly send plastic containers that still contain food \u2013 yogurt for example \u2013 to the landfill because the residue taints the recycled material.<\/p>\n\n\n\n

Most plastic starts with fossil fuels. Refiners heat oil and natural gas to \u201ccrack\u201d the large molecules into smaller molecules, among them ethylene and propylene. Those chemicals are the building blocks used to make a variety of plastics. By linking the monomers, plastics manufacturers create a long chain molecule called a polymer, or a plastic.<\/p>\n\n\n\n

\n

\u00a0\u201cOur extraction process retains key, core monomers, so they can be reinserted into the polymerization process,\u201d Dorman<\/strong> said. \u201cFor example, we can pull the ethylene from the polyethylene during recycling and use it to make new polyethylene.\u201d<\/p>\n<\/blockquote>\n\n\n\n

Ethylene and propylene are extremely valuable. The global market for ethylene alone is estimated at $150 billion.<\/p>\n\n\n\n

\n

\u201cBy recycling these chemicals, we can help reduce the need for new fossil fuels and lower greenhouse gas emissions,\u201d Dooley<\/strong> said. \u201cBasically, our extraction process helps clean up the environment and creates a way to make money from what was once trash.\u201d<\/p>\n\n\n\n

\u201cThis breakthrough in plastic recycling is a crucial step in our Scholarship First Agenda mission to build a research platform for energy resilience,\u201d said LSU Vice President of Research and Economic Development Robert Twilley<\/strong>. \u201cBy innovating processes that increase the recycling of carbon-based materials and reduce carbon emissions, LSU is addressing the challenge of plastic waste and helping to create a sustainable energy future.\u201d<\/p>\n<\/blockquote>\n\n\n\n

Dorman and Dooley have worked with the LSU Office of Innovation & Technology Commercialization (ITC) to pursue patent protection for their invention.<\/p>\n\n\n\n

\n

\u201cWe\u2019re excited about helping Drs. Dorman and Dooley explore the commercial possibilities for this cutting-edge technology,\u201d said Daniel Felch, LSU ITC senior commercialization officer.<\/strong><\/p>\n<\/blockquote>\n\n\n\n

About LSU\u2019s Office of Innovation & Technology Commercialization<\/strong><\/h3>\n\n\n\n

LSU\u2019s Office of Innovation & Technology Commercialization (ITC) protects and commercializes LSU\u2019s intellectual property. The office focuses on transferring early-stage inventions and works into the marketplace for the greater benefit of society. ITC also handles federal invention reporting, which allows LSU to receive hundreds of millions of dollars each year in federally funded research, and processes confidentiality agreements, material transfer agreements and other agreements related to intellectual property.<\/p>\n\n\n\n

About the LSU Office of Innovation & Ecosystem Development<\/strong><\/h3>\n\n\n\n

LSU Innovation unites the university\u2019s innovation and commercialization resources under one office, maximizing LSU’s impact on the intellectual, economic and social development of Louisiana and beyond. LSU Innovation is focused on establishing, developing and growing technology-based startup companies. LSU Innovation oversees LSU Innovation Park, a 200-acre business incubator that fosters early-stage tech companies, and the Office of Innovation & Technology Commercialization, which streamlines the process of evaluating, protecting and licensing intellectual property created by LSU researchers. LSU Innovation serves as the host organization for the Louisiana Small Business Development Center (SBDC) network, which oversees all SBDC services across the state as well as the LSU SBDC, which provides free consulting services to small businesses across the state. LSU Innovation helps Louisiana technology companies apply for seed funding through the federal Small Business Innovation Research and Small Business Technology Transfer grant programs. LSU Innovation educates faculty, students and the community on entrepreneurial principles through the National Science Foundation\u2019s Innovation Corps (I-Corps) program, which trains innovators to consider the market opportunities for pressing scientific questions, leading to increased funding from state and federal grant programs as well as industry partners and licensees.<\/p>\n\n\n\n
