In an effort to make wind power as green as possible Dutch rotor blade manufacturer Aerpac has joined forces with certification agency KEMA to develop an organic rotor blade. Instead of using glass fibres to strengthen the polyester and epoxy resin of turbine blades, Aerpac is experimenting with natural fibres from wood and flax. The company is also investigating special binding techniques that will make it possible to transport large blades in sections, which can then be assembled on site. In a subsequent project, which will also involve the the Netherlands' Energy Research Foundation (ECN), the Technical University of Delft and the Agrotechnological Research Institute (ATO/DLO), the possibilities for recycling blades will also be examined.
