Discarded Wind Turbine Blades Are Upcycled into Sleek Bike Shelters in Denmark

It’s estimated that before 2050, we’ll generate 43 million tons of waste worldwide from one of the most promising clean energy producers alone. Wind turbines, while a cheap and carbon-free alternative to fossil fuels, are only 85 percent recyclable or reusable, and their massive fiberglass blades, which are so large that they span the length of a football field, are notoriously difficult to break down and often end up deteriorating in a landfill for 20 to 25 years. Until a high-volume solution for recycling the structures becomes viable, there’s a growing trend in repurposing the pieces for maze-style playgrounds, construction materials like pellets and panels, or pedestrian bridges as proposed by Re-Wind Network, a group devoted to finding new uses for the unused parts.

A long-time proponent of wind energy, the Danish government is receiving attention for its own initiative that tasked turbine manufacturer Siemens Gamesa with upcycling the blade. The company transformed the long, curved component into an open-air shelter at the Port of Aalborg, where it protects bikes from the elements. Although Siemens Gamesa doesn’t have plans to launch a large-scale initiative for installing similar designs, it recently released new fully recyclable blades that can be turned into boats, recreational vehicle bodies, and other projects in the future.
