The article describes how municipal plastic waste (MPW) is used in the building industry. Plastic is a material that is not biodegradable and takes thousands of years to disintegrate, polluting both land and water. Municipal Solid garbage (MSW) contains an increasing amount of plastic garbage. Every ten years, the rate of utilization is thought to double. Polyethylene (PE), one of the most abundant plastic wastes, is consumed in vast quantities. The use of earth-based clay material led to the depletion of resources and the damage of the environment. The cost element decreases because plastic garbage is typically available in plenty. Since these brick blocks are good water absorbing and have greater compressive strength. Therefore, because they have a good water absorption limit and a higher compressive quality, these types of brick blocks are best used for underground pits and water tank construction, and building construction. We looked into and evaluated the characteristics of the composite bricks. Strength, water absorption, and other characteristics were comparable to those of traditional bricks. This waste-derived brick will be practical and offer an enduring solution.
