In this globalized era, building materials play an essential role in the civil engineering field. nowadays, with the increase in population, the demand for construction activities is also increasing. Polyethylene (Pet) bottles are among the most widely used materials and cause an abundance of non-degradable waste, at about 0.94 million tonnes in Malaysia. one of the alternatives to reduce this waste's environmental impact is to incorporate it inside building materials such as brick and concrete. as Pet bottles' recycling is highly promoted, the physical and mechanical properties of building materials made from Pet bottles have also been reviewed. the data analysis shows that the compressive strength, flexural strength, split tensile strength and density of building materials decreases as the percentage of Pet waste increases. however, other properties such as water absorption, initial absorption rate, and firing shrinkage increase proportionally with the Pet waste. besides, heavy metals in these building materials comply with the united states environmental Protection agency (usePa) standards. It can be concluded that the percentage of Pet waste incorporated into brick and concrete must be less than 5% and 2%, respectively, to produce suitable materials to provide alternatives in reducing and recycling Pet waste.
