Tiles industry is the prime ceramic product which widely uses in Sri Lanka. Wall tiles, Floor tiles, and Roof tiles are the major products of tile industry outlet. In Sri Lankan building construction applications, ceramic floor tiles show a significant contribution when compared with other floor development materials Today’s world is more concerned about environmental awareness with continuous growth unsustainable manufacturing practices. Therefore, many manufacturers are trying to create more and more eco-friendly processes and products by minimizing the effects of their activities on the environment. Although, as a developing country, the environmental performance of the tiles manufacturing sector and improvement of the product quality and performance are key factors to improve the sustainability. In order to go for a green future, it is needed to identify the environmental hotspots generates by the manufacturing sector. the product life cycle assessment (LCA) is an effective tool in the identification of environmental hotspots. In addition to that, it is required to model different life cycle scenarios for the improvement of Life Cycle Management (LCM). Therefore, this research focuses on conducting LCA towards eco-design on floor tile industry by using sensitivity analysis as well as scenario analysis. Through this study, local floor tile industry can be driven to improve its overall sustainability of the floor tile manufacturing sector.
