eng	Composite materials from unsaturated polyester resins and quartz powder	This study focuses on chemical recycling of polyethylene terephthalate glycol (PETG). It is popular material for growing 3D printing industry where it is used as filament in fused deposition modeling (FDM) printers. This growing trend means more polymeric waste. In this study the waste PETG was chemically recycled via glycolysis. Furthermore, the unsaturated polyester resin was prepared from this glycolysate. This resin was then mixed with quartz powder to create composite material with enhanced mechanical properties. Mechanical testing was performed on universal testing machine. The addition of quartz powder caused the Young’s modulus to increase. Hardness tests showed higher values in composites with higher amount of quartz powder. This material was also able to retain glossy surface. Fracture surfaces were examined by scanning electron microscopy (SEM).	Unsaturated polyester resin; PETG; quartz powder; composite material
