Plastic Waste Utilization in Sustainable Construction Materials: A Sustainable Approach for Waste Management and Green Construction
Summary
This review paper looks at how waste plastic (like bottles and packaging) could be mixed into concrete, roads, and bricks instead of piling up in landfills or being burned, which pollutes air and water. The findings suggest this could make building materials cheaper and more durable while cutting down plastic pollution, though the paper doesn't address whether these materials might shed microplastics over time, which is worth watching as this approach gets adopted. This is a summary of existing research rather than new lab testing, so more real-world studies are needed before we know the full health and safety picture.
The rapid increase in plastic consumption has resulted in significant environmental challenges due to improper disposal and accumulation of plastic waste. Conventional disposal methods such as landfilling and incineration contribute to environmental degradation and greenhouse gas emissions. The construction industry offers a promising solution through the utilization of plastic waste in building materials. This study reviews the potential of incorporating plastic waste into concrete, asphalt pavements, bricks, blocks, and composite materials. The environmental, economic, and engineering benefits of plastic-modified construction materials are analyzed. Results from previous studies indicate that plastic waste can improve durability, reduce material costs, and minimize environmental pollution while promoting sustainable construction practices. The study concludes that plastic waste utilization can play a significant role in achieving circular economy objectives and reducing the environmental footprint of the construction sector.
