On the Cementitious Mixtures Reinforced with Waste Polyethylene Terephthalate

Researchers investigated the reuse of waste polyethylene terephthalate plastic as aggregate material in cement mortars and concretes. They found that incorporating PET waste into cementitious mixtures can be a viable strategy for recycling plastic while also reducing CO2 emissions from traditional aggregate mining. The study suggests that closing the life cycle of PET through construction materials could help address both plastic pollution and the environmental footprint of the building industry.
