This work brings up the issue of the recycling of residues made of polyester reinforced glass fibres (PRGF), as well as the involved recycling technology. The future PRGF growth projections have led to an increased attention of the post-consumed products. For PRGF, it is observed that three recycling routes are available: mechanical, chemical or energy recovery. The mechanical recycling is attained by means of grinding a material, which has characteristics that allow its reuse. This paper deals with powder technology processing of residues, by reviewing the available technologies and processes aiming the PRGF recycling.
