Now a day there are huge amount of solid wastes in the world and are taken as a big challenge to the environment. Because of their environmental impact, the highest attention has been given for recycling of plastics in both consumer products as well as engineering plastics. The objective of this work is to study the recyclability of waste polystyrene co-polymers namely, PS-HI and PS- FR and their application in industrial sector. Material collection, cleaning, sorting, size reduction and granule and product characterizations are sequential activities done during study period. Basically, three characterizations namely chemical characterization (FTIR and EDX), Thermal (TGA, DSC and Cone calorimeter) and mechanical characterization (Tensile stress, Tensile modules and Elongation at break) of high impact polystyrene (PS-HI) and polystyrene with flame retardant additive (PF-FR) was carried out. Finally, after testing Plastic processing (melt flow and Extrusion) and mechanical characterization (tensile strength and modulus), PS-HI sample shows better properties in all aspects and it is taken as a best sample for 3D printing application.
