German scientists develop natural fiber wind turbine blades to reduce waste
Germany is taking a natural turn in wind energy.
A new initiative led by Kiel University of Applied Sciences (HAW Kiel) and boatbuilder Nuebold Yachtbau GmbH aims to build rotor blades made entirely from renewable materials—flax, balsa wood, and paulownia—in a bid to replace fiberglass and shrink the industry’s mounting waste footprint.
Backed by roughly €175,000 from the Schleswig-Holstein Energy and Climate Protection Agency (EKSH), the team plans to develop a prototype for small wind turbines (with rotor areas under 200 square meters) by 2027.
“We want to demonstrate that sustainable rotor blades made from flax fibers and other renewable raw materials can meet all technical requirements and thus make a real contribution to a more sustainable wind energy sector,” said Prof. Dr.-...
