A Danish startup is attempting to turn decommissioned wind turbines into noise pollution barriers surrounding highways and factories.

Built to withstand excessive temperatures and other extreme conditions, wind turbines tend to be difficult to recycle, oftentimes ending up in landfills. Yet, Copenhagen-based Miljoskarm has devised a method for pulverizing wind turbine blades using machinery similar to that found in automotive junkyards, grinding the components down to 1 to 2 cm pieces. Once reduced, those pieces are enveloped in recycled plastic panels to serve as noise pollution barriers.

According to Miljoskarm, the recycled wind turbines, which are typically composed of fiberglass and plastic, work as well as current barriers, which tend to be composed of aluminum and mineral wood. Yet, according to developers, the wind turbine-derived noise pollution barriers require less maintenance than current iterations.

This and other solutions for recycling wind turbines are coming at a time when the first generation of wind turbines are nearing or reaching their end of life, presenting an issue in terms of discarding the enormous components.

In addition to being used as a composite material for the manufacturing industry, an initiative was recently launched in the U.K. to turn decommissioned wind turbines into material for cement.
