Investigating the Use of Post-Consumer LDPE Waste and Stone Dust in Sustainable Concrete Composites
Researchers incorporated post-consumer LDPE plastic waste and stone dust into concrete mixes and found that these additions can maintain acceptable mechanical properties. Reusing plastic waste in construction materials diverts plastics from landfills and reduces their potential to fragment into environmental microplastics.
Integrating Plastic Waste into Concrete: Sustainable Solutions for the Environment
This review examines research on incorporating plastic waste into concrete as a partial replacement for conventional aggregates and cement. Researchers found that adding recycled plastic can reduce concrete density and improve thermal insulation properties, though it generally decreases compressive strength at higher replacement ratios. The study suggests that optimizing plastic content and treatment methods could make this approach a viable strategy for diverting plastic waste from landfills.

Potential improvement in the mechanical performance and thermal resistance of geopolymer with appropriate microplastic incorporation: A sustainable solution for recycling and reusing microplastics
Researchers tested whether microplastics of various sizes could be incorporated into geopolymer, a cement-like construction material, as a way to recycle plastic waste. Adding small amounts of microplastics actually improved the material's strength and heat resistance up to 400 degrees Celsius. This approach offers a potential solution for trapping microplastics in building materials rather than letting them pollute the environment and threaten human health.
A critical review of the current progress of plastic waste recycling technology in structural materials
Researchers reviewed technologies for recycling plastic waste into construction materials such as concrete and asphalt, finding this approach can meaningfully reduce the environmental burden of plastic pollution. Incorporating plastic waste into building materials offers a practical path toward both waste reduction and more sustainable construction.
