HOUSTON, TEXAS (KTRK) — A 2023 report from the Texas Comptroller’s Office shows that wind energy is only second to natural gas when it comes to energy production in the state. Since then, a new wind farm in Wharton County opened in May 2024, which produces 160 megawatts of power that’s sent right into the Texas grid. But critics claim that this form of green energy is not so green at all.
In its simplest form, wind turbine blades are made of recyclable materials. But it’s the outer resin that makes it extremely difficult to recycle these blades using traditional methods. So many parts of retired turbines end up in massive landfills referred to as “windmill graveyards.”
But a research group at the University of Houston has figured out how to give these once unrecyclable blades a second life through upcycling practices. That’s when you take an old material, repurpose it, and create something new. For wind turbines, this prevents them from ending up in landfills and extends their lifespan by 20 to 50 years.
Dr. Gangbin Song, a mechanical engineering professor at the University of Houston, and his team created a prototype of an overhead sign, like the kind you’d see on a highway, out of old blades.
“As a matter of fact, most people, when they see this, they thought these are new structures. And I told them those are retired structures,” Dr. Song said when referring to blades.
Through their research, the team has discovered that these decommissioned blades are six times as strong as concrete and 10% stronger than steel. This team believes something this strong is too valuable to go to waste. And their strength means these blades are already up to code for a variety of different uses. A few examples of rendering the team created were those of pedestrian bridges, benches, shade canopies, and even children’s playgrounds.
Furthermore, associate professor Bradley Davis tells ABC13 that the supply of decommissioned blades is in place for the next 30 years.
“Our goal is to take something that currently is a liability for wind farm operators and turn it into an asset,” Davis said.
