Abstract: Fly-ash is a waste from coal-based thermal power plant. Grocery bags commonly made from polyethylene and packaging foam which is expanded polystyrene are also two types of waste plastics. All these solid wastes pose an environmental threat. In this article, development of composite tiles from these solid wastes and their physico-mechanical characterisation has been described. Mass ratios of polyethylene to fly-ash (A) and polystyrene to fly-ash (B) were correlated with the respective solvent resistances, tensile and flexural strengths of the tiles through simple equations. The agreement of the proposed models and the experimental data was found to be excellent. Indian standard for the common ceramic tiles is compared with the developed ones. The product is found suitable as a wall tile. This may help in sustainable disposal of these bulk solid wastes whose safe disposal is still a huge problem.
