The colorless beverage glass packaging was collected by the authors in bars and supermarkets located in Campos dos Goytacazes, RJ, Brazil. The quartz dust was supplied by EcologicStone, an artificial stone company located in Cachoeiro de Itapemirim, ES, Brazil. The epoxy resin (MC130) of type diglycidyl ether bisphenol A (DGEBA) with 1.15 g/cm<sup>3</sup> density and the hardener (FD 139), composed of triethylenetetramine (TETA) were both supplied by Epoxyfiber.

The size reduction of wastes was achieved by the fine sieving method according to ABNT NBR 7181 [20], in order to obtain three granulometric ranges: coarse (2.000–0.420 mm), medium (0.420–0.075 mm), and fine particles (<0.075 mm). The glass bottles were crushed in a ball mill in order to obtain coarse and medium granulations, and the quartz dust was already fitting the fine granulometry.
