Eco-friendly bricks: a sustainable solution with high-density polyethylene HDPE

Concrete and bricks constitute the foundation in modern construction; however, their conventional manufacturing processes significantly contribute to carbon emissions. The rising demand for bricks compels the construction industry to seek sustainable alternatives urgently. An innovative solution may involve tackling another environmental concern—plastic waste. Polyethylene Terephthalate (PET), a plastic frequently utilised in water bottles, demonstrates significant potential as a sustainable additive in brick production, minimising waste while improving brick performance. This research investigated the incorporation of PET in concrete bricks to mitigate plastic waste and enhance brick durability. The incorporation of PET as a partial substitute for fine aggregate enhances the eco-friendliness of bricks while maintaining their structural integrity.
