In this research, industrial factory wastes causing environmental pollution were evaluated in polyester composite production. The effect of industrial factory wastes on the change of properties such as density, hardness, thermal stability and mechanical strength of unsaturated polyester composites was investigated. Especially, factory wastes such as colemanite, ulexite, clay and ash were used as fillers in the production of polyester composites. Composites were obtained by mixing different proportions of fillers, pure unsaturated polyester, methyl ethyl ketone peroxide (MEKP) and cobalt octoate in certain amounts by mass. Chemical bond structure (FTIR), surface morphology (SEM), thermal stability (TGA), Shore D hardness, mechanical strength and thermal conductivity coefficient of polyester composites were determined. It has been determined which properties are positively or negatively affected by adding 5% (wt.) to the polyester composite separately as industrial factory waste filler. It has been observed that the pore matrix in polyester composites affects the thermal conductivity coefficient. As the mass percentage of fillers increased, the hardness, thermal stability, density and thermal conductivity coefficient of the polyester composite increased. It was also observed that the modulus of elasticity and mechanical properties of the composite decreased. In addition, thermal decomposition kinetics of polyester composites were modeled with the help of statistical analysis.
