Utilization of glass fiber reinforced polymer wastes

open access: yesPolymer Composites, 2020
AbstractSince they arises in many stages of manufacturing as well as at the end of their lifetime, glass fiber reinforced polymers‐based wastes are one of the biggest problem for the composite industry. There are many waste disposal methods available, but these are low value‐added and usually imply additional cost to the manufacturers.
