Utilization of Waste Plastic in the Fabrication of Sustainable Bricks : A Comparative Study on Strength and Feasibility

The ever-increasing accumulation of plastic waste has emerged as a critical environmental concern, largely due to its non-biodegradable nature and hazardous effects on ecosystems.To address this issue sustainably, the conversion of waste plastic into construction bricks offers a promising alternative to conventional waste disposal methods.This paper highlights the potential applications of plastic bricks across various sectors.These bricks, made by thermally processing and molding waste plastics, exhibit durability, water resistance, and thermal insulation properties.They can be effectively used in non-load-bearing construction such as pathways, garden walls, temporary shelters, road paving blocks, and low-cost housing components.Moreover, their lightweight nature and resistance to moisture make them ideal for use in coastal or flood-prone regions.By integrating plastic bricks into mainstream construction, this solution not only reduces environmental pollution but also supports the development of low-carbon, sustainable infrastructure.
