Reducing the noise of wind turbines with FeatherEdge® serrations

Nature inspired design utilizing plastic material performance from thermoset to thermoplastics

When air moves, it makes noise. By adjusting turbine blade aeroacoustics, FeatherEdge® technology directs air flow to mix at discrete locations to reduce noise emissions and improve turbine performance, benefits appreciated by operators, regulators, and the local community.

FeatherEdge® reflects a successful translation of biomimicry into commercial wind energy innovation: from the quiet flight of an owl to tangible noise- and performance‑enhancing serrations for turbine blades. The components made of TPU ensure durability. With measurable reductions in noise and boost to yield, Biome Renewables is positioning FeatherEdge® as a scalable retrofit or factory-installed upgrade across Europe and North America.
