Iowa Uses Recycled Wind Turbine Blades in Construction

Wind turbine blades are getting a second life as construction barriers in Iowa, solving a major recycling challenge while keeping jobsites safe.

Graham Construction just installed 28 concrete barriers at Mercy College of Health Sciences in Des Moines, but these aren't ordinary safety walls. Each barrier contains recycled composite material from retired wind turbine blades, giving new purpose to equipment that usually ends up in landfills.

The barriers come from Renewablade, a company in Bondurant, Iowa, that specializes in turning decommissioned turbine blades into construction materials. The 28 barriers installed at Mercy College contain recycled material equal to one complete wind turbine blade.

Wind turbine blades present a unique recycling problem. Made from tough composite materials designed to withstand extreme weather for decades, they're incredibly difficult to break down or repurpose. Most end up buried in landfills despite coming from renewable energy systems meant to help the environment.

"Projects like this show that jobsite safety and sustainability can go hand-in-hand," says Mike Berry, field operations leader at Graham Construction. The barriers protect workers near a busy street on Mercy College's downtown campus while giving retired renewable energy equipment a practical second purpose.

The Ripple Effect

This marks Renewablade's second major downtown Des Moines project. Earlier this year, Premier Credit Union completed a retaining wall using Renewablade blocks made from three retired wind turbine blades.

The impact goes beyond just two projects. As wind energy grows across the Midwest, thousands of first-generation turbine blades will need retirement homes in coming years. Solutions like Renewablade's barriers and retaining walls create a path forward that keeps these materials working instead of wasting space in landfills.

The technology proves that circular construction works in real-world applications. Retired renewable energy materials can become durable infrastructure for everyday use, closing the loop on sustainability while meeting practical construction needs.

Iowa is showing other states how to turn a waste problem into a building solution.
