Transforming waste into innovation: a review of plastic bricks as sustainable construction materials

Abstract

AbstractPlastic waste has become a pressing global issue, posing significant environmental challenges. As the construction industry continues to grow, there is a growing need for sustainable construction materials that can address this problem. This review paper focuses on the transformation of waste into innovation by exploring the use of plastic bricks as sustainable construction materials. The paper examines the manufacturing processes, properties, environmental benefits, challenges, case studies, and future research directions associated with plastic bricks. It highlights the potential of plastic bricks to reduce plastic waste, carbon emissions, and resource consumption. Additionally, the review addresses the challenges related to structural integrity, long-term durability, regulatory compliance, and public perception. Case studies showcase successful implementations of plastic bricks in construction projects, emphasizing their innovative design possibilities, cost-effectiveness, economic feasibility, and notable structural strength. These case studies illustrate that plastic bricks can achieve the necessary strength for construction applications, making them a viable alternative to traditional materials. The paper also discusses the environmental impact and circular economy perspectives of plastic bricks, highlighting their recyclability, reusability, waste management implications, and contribution to circular economy initiatives. Finally, the review concludes with future research directions and recommendations, focusing on advancements in manufacturing techniques, enhanced performance and engineering properties, and long-term performance monitoring and assessment. This comprehensive review sheds light on the transformative potential of plastic bricks as sustainable construction materials and provides insights for addressing the global plastic waste problem.
