An Analysis of Using Plastic Wastes to Make Bricks

Abstract

Plastic waste is growing daily and pollutes the environment, making it unsightly. This is especially true in high mountain towns without a garbage collection infrastructure. The ecology and air are contaminated by the massive amounts of plastic that are transported into the tourist trekking areas and either discarded or burned. It is therefore necessary to make good use of these leftover polymers. One of the best ways to prevent the accumulation of plastic waste, which is a biodegradable pollutant, is to clean low-density polyethylene bags and add sand to them in specific percentages to create high-strength bricks with thermal and sound insulation qualities. This reduces overall construction costs and pollution. By doing this, the amount of sand or clay that needs to be removed from the priceless riverbeds and mines is instead saved. Since there is a natural abundance of plastic garbage, the cost component decreases. For the combination to have the correct tones, colouring agents can also be added. Thus, an attempt is undertaken in this thesis to investigate the characteristics of brick formed from plastic trash. The production and examination of bricks manufactured from waste plastic (LDPE) and fine aggregates are the subjects of the current study. The resulting bricks are extremely low in water absorption, have a high crushing strength, a smooth surface, fine edges, and no cracks. They are also light in weight. The process of making bricks involves melting scrap plastic to a temperature between 120 and 150 degrees Celsius and then combining it with sand.
