The increasing accumulation of plastic waste poses significant environmental challenges, contributing to pollution and resource depletion. The construction industry, traditionally reliant on non-renewable materials, faces increasing pressure to adopt sustainable practices. This study addresses the urgent need for innovative solutions that utilize recycled plastics in construction, thereby mitigating waste and enhancing material sustainability. This study aims to address the problem of plastic waste management by evaluating the production of interlocking bricks from waste polyethylene terephthalate (PET) and low-density polyethylene (LDPE) plastic. The objectives include assessing the mechanical properties, structural integrity, and durability of these polymeric bricks as sustainable alternatives to traditional building materials. Given the high rates of plastic waste generation and the reliance on natural raw materials for brick production, this research seeks to explore innovative solutions that utilize recycled materials effectively. A systematic methodology was employed to design the mixtures, focusing on varying the sand-to-polymeric waste ratios. Compressive and flexural strength tests were conducted to assess the bricks' ability to withstand vertical loads and bending forces, respectively. Water absorption and density tests were performed to determine durability and suitability for external use. Results indicated that the 70:30 PET to sand mix ratio provided the best performance, with an average compressive strength of 7.86 MPa and flexural strength of 21.94 MPa. The findings suggest that using PET plastic waste in interlocking brick production can enhance material properties while contributing to environmental sustainability.
