Abstract : Plastics play an essential part in modern society and are widely employed in a variety of applications due to their low cost, simplicity of production, and appealing qualities. Every year, around 300 million tons of plastic are manufactured worldwide, with only about 25% recycled. The fundamental issue with plastic garbage is that it may modify the living environment and natural processes, diminish ecosystems' ability to adapt to climate change, and significantly impact the livelihoods, social welfare, and food production capacity of millions of people. The purpose of this study was to assess the utilization of plastic trash to minimize the demand for cement in constructing blocks. Plastic and concrete blocks were tested as part of this study. Plastic blocks have a sand-to-plastic ratio of 7:3, whereas concrete has two ratios: 1:6 and 1:8. Three machines are used to make plastic blocks: one crusher, two for blending plastic and sand, and one for burning plastic. Polymers were deposited in a 150x150x150mm mold after one hour in the burning process. Concrete blocks are made using the conventional process of combining cement and coarse sand. The molding is then put into the mold. It started mending after 24 hours and will continue for 7 days. According to the findings, the percentage of water absorption in plastic blocks is lower than in concrete blocks. Plastic bricks offer better compressive strengths and are less expensive than concrete blocks, according to this study.
