Methods of Initial Assessment for Safety Secondary Application of Duroplastic Waste

The powder recyclate was obtained through the mechanical processing of GRP waste (pipes,wind turbine blades). Currently, there are no specific quality requirements or standards for such secondary material due to the lack of its large scale usage. However, pending regulations dedicated to the secondary markets, it is necessary to develop facilitate the potential introduction of the material on an industrial scale. The recyclate was analyzed using gas chromatography (GC), high-performance liquid chromatography (HPLC), and Fourier-transform infrared spectroscopy (FTIR).
