ClearSystematic Review of Plastic Waste as Eco-Friendly Aggregate for Sustainable Construction
This systematic review examines how recycled plastic waste can be used as a substitute for traditional aggregates in concrete and construction materials. Using plastic waste in construction could divert it from landfills and waterways where it breaks down into microplastics. The review evaluates the structural performance and environmental benefits of incorporating plastic into building materials.
Potential use of PET and PP as partial replacement of sand in structural concrete
Researchers tested whether PET and polypropylene plastic waste could partially replace sand in structural concrete, evaluating the physical and mechanical properties of the resulting material. Using post-consumer plastic in construction is one strategy for diverting plastic from the waste stream and preventing it from breaking down 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.

Researchers investigated the use of recycled high-density polyethylene (HDPE) plastic waste as an aggregate in concrete pavement mix designs, finding that incorporation of HDPE improved mechanical performance and durability while reducing landfill waste and energy consumption in the concrete sector.
Review- Using Ground Bakelite as Alternative Solution for the Replacement of Fine Aggregate
This paper is not relevant to microplastics research — it evaluates ground Bakelite waste as a partial replacement for fine aggregate in concrete construction, focusing on materials engineering rather than plastic particle pollution in the environment.
Recycling/reuse of plastic waste as construction material for sustainable development: a review
Researchers reviewed how waste plastic can be incorporated into construction materials — as binders, aggregates, or cement substitutes in bricks, tiles, concrete, and roads — finding that plastic-modified materials often show competitive strength properties while simultaneously diverting plastic waste from landfills.
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.
Eco-friendly Concrete Using Waste Plastic Bottles as Aggregate: A Case Study from Oman
This Omani study tested concrete made with waste plastic PET bottles as a partial replacement for fine aggregate. Adding recycled plastic to concrete is a promising strategy to divert plastic waste from the environment, and the study found acceptable mechanical performance for non-structural applications.
