Environmental impact and waste recycling technologies for modern wind turbines: An overview

Wind power is rapidly expanding worldwide, and so is the installation of wind turbines. The concept of wind power as a clean-energy alternative will be questioned if the waste from these turbines is not and adequately controlled. The goal of this review paper is to evaluate the various approaches for end-of-life management of wind turbine blades emphasizing on fibre recovery. Different methods for recovering carbon and glass fibres are described, including thermal treatment and chemical treatments and their economic and environmental comparisons. Life cycle assessment and comparative analysis of different recycling processes are also presented. Natural composites, modified thermoset composites, and thermoplastic composites are also covered as alternative environmentally friendly blade materials.
