Iowa Company Turns Wind Turbine Blades Into Road Barriers

What do you do with a 116-foot wind turbine blade that weighs several tons and can't be thrown away? One Iowa company has found the perfect answer, and it's protecting construction sites across America.

Renewablade, based in Bondurant just outside Des Moines, is turning retired wind turbine blades into concrete traffic barriers. Those familiar orange and white barriers you see around road work? They're getting a sustainable upgrade.

Founder Nick Wylie saw an opportunity where others saw waste. Wind turbine blades are made from fiberglass, balsa wood, resin, foam, and steel, creating a recycling nightmare when turbines reach the end of their 20 to 25 year lifespan. Some blades stretch nearly 200 feet long, and Iowa produces more wind energy than almost any other state.

The company collects retired blades from as far away as Maine and Washington. They either travel to decommissioned wind farms to cut and haul the massive blades, or customers deliver sections directly for a tipping fee. Either way, Renewablade ensures nothing ends up in a landfill.

The process is surprisingly straightforward. The blade sections get shredded and mixed into ready-mix concrete to create 10-foot barriers weighing 3,300 pounds each. The recycled blend produces barriers that are 30 percent lighter than traditional concrete but just as strong.

The economics make perfect sense too. Traditional DOT-certified Jersey barriers cost between $1,200 and $1,500 each. Renewablade sells theirs for just $500, making safety equipment more accessible to construction companies and municipalities.

The Ripple Effect

Renewablade isn't just making barriers. The company has expanded into landscaping blocks for retaining walls and other large-scale concrete products, creating multiple pathways for turbine blade materials to find new life.

What sets Renewablade apart is completing the circle. While other companies have started collecting and shredding old turbine blades, Wylie says his team is the only one turning that material into finished products at scale. They've created an actual end game for materials that previously had nowhere to go.

The supply keeps growing as America's first generation of wind farms reaches retirement age. Wylie says there's an endless stream of blades that need recycling, ensuring his company will have raw materials for decades to come.

Every barrier Renewablade produces represents tons of composite material diverted from landfills, cost savings for safety-conscious companies, and proof that recycling challenges can become business opportunities. The wind energy that powered our transition to clean electricity is now protecting workers on our roads.
