ClearPerformance of recycled Bakelite plastic waste as eco-friendly aggregate in the concrete beams
Researchers tested concrete mixtures containing recycled Bakelite plastic waste as a partial substitute for stone aggregate, finding that adding up to 10% Bakelite generally reduced strength but prevented sudden cracking during failure. While this offers a way to divert hard-to-recycle plastic from landfills — where it would otherwise slowly break down into microplastics — the strength trade-offs must be carefully managed in structural applications.
Experimental Tests on Lightweight Cement Mortar and Concrete with Recycled Plastic Wastes

Can Microplastics (MPs) Replace Conventional Mineral Aggregates? A Brief Review
Could plastic waste be repurposed as a substitute for sand and gravel in concrete? This review examined the science and found that microplastics generally perform poorly as construction aggregates — weakening concrete, reducing durability, and posing a risk of releasing secondary microplastics over time. While some niche, non-structural applications might be feasible under controlled conditions, the authors caution against treating plastic-for-aggregate substitution as a general solution to plastic waste, as the trade-offs in building performance and environmental risk are significant.
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.
Potential use of PET and PP as partial replacement of sand in structural concrete
