MSE Alumni Give New Life to Old Wind Turbine Blades<\/p>\n

Wind energy is one of America\u2019s largest domestic sources of renewable energy. It\u2019s clean, economical, and readily available, but it has a problem: what to do with those gigantic blades once they need replacing.<\/p>\n

\"RyanMSE alumni Ryan Ginder (PhD \u201916) and Bowie Benson (BS \u201917) have teamed up to find a solution.<\/p>\n

Manufacturers of the blades rely on advanced polymer composites to be able to withstand the elements of nature. Although eventual wear and tear are inevitable, sending them to the landfill doesn\u2019t have to be.<\/p>\n

\u201cAs the wind industry grows and waste blade levels climb into the tens, hundreds of thousands of tons and beyond, a better end of life solution is needed rather than simply piling them at the dump,\u201d said Ginder who is now a research assistant professor in UT\u2019s Department of Mechanical, Aerospace, and Biomedical Engineering<\/a>.<\/p>\n

A team of UT researchers led by Ginder is developing new technology for the large-scale handling and recycling of these wind turbine blades.<\/p>\n

The technology recovers the glass fiber from reinforced polymer composites while limiting mechanical degradation of the fiber during the reclamation process. This, in turn, allows the recycled fiber to be reused in new composite applications such as vehicle lightweighting, other renewable energy systems components, and performance sports equipment.<\/p>\n

While the US wind industry has made substantial contributions to America\u2019s renewable energy portfolio, work is ongoing to convert the industry to a more circular economy paradigm.<\/p>\n

\u201cRather than simply downcycling the blades into worthless aggregates, we are able to not only convert the blades\u2019 organic components into useful petrochemicals for energy production but also able to extract the glass fiber reinforcement and use it to make higher-value recycled composites,\u201d said Ginder.<\/p>\n

Carbon Rivers LLC, a start-up company located in Knoxville and owned by Benson, has partnered with Ginder to further develop and commercialize this novel technology. The project has been awarded $1.1 million in funding from the Department of Energy\u2019s Small Business Technology Transfer program and Wind Energy Technologies Office.<\/p>\n

\u201cHaving the opportunity to collaborate with the bright minds at UT, like Dr. Ginder, and catalyze new solutions for our country\u2019s plastics waste problem, is a Volunteer\u2019s dream come true,\u201d said Benson. \u201c2020 has been a challenging year all around for our community, but I remain hopeful for the future as long as we keep working together to take on the tough challenges, like making American energy more sustainable. I am especially optimistic about our project\u2019s next phase, and it’s potential to transformatively improve the wind industry\u2019s environmental footprint while creating new, much-needed jobs in East Tennessee.\u201d<\/p>\n

Over the next two years, the UT-Carbon Rivers team will be collaborating with GE Renewable Energy, Berkshire Hathaway Energy\u2019s MidAmerican Energy Company, and PacifiCorp Utilities to develop a pilot-scale glass fiber composite recycling system that will serve as the basis for the eventual deployment of a full-scale commercial wind blade waste processing plant.<\/p>\n
