ClearPreparation of Waste PP/Fly Ash/Waste Stone Powder Composites and Evaluation of Their Mechanical Properties
Not relevant to microplastics — this paper examines the mechanical properties of composite materials made from recycled polypropylene combined with fly ash and stone powder for industrial construction applications.
Investigation of physical properties of microalgae‐pectin‐based bio‐composite with addition of pine needle for environmental application
This paper is not directly about microplastics — it investigates the physical properties of a bio-composite material made from microalgae, pectin, and pine needles as a potential alternative to petroleum-based plastics, without studying microplastic pollution or environmental impacts.
A Study of Plant-Filled Polymer Composites Based on Highly Plasticized Polyvinyl Chloride
Not relevant to microplastics — this is a polymer materials study developing plant-filled PVC composites (using spruce flour, birch flour, and rice husk as fillers) to improve the ecological profile of PVC products, with testing of mechanical and thermal properties.
Material Development and Properties of Medium-Density Board from Low and High-Density Polyethylene
Not directly relevant to microplastic pollution research. This engineering study creates medium-density boards from waste polyethylene plastics and tests their mechanical properties for use in furniture and construction—a materials recycling study rather than a pollution or health impacts study.
Compatibility of Polymer/Fiber to Enhance the Wood Plastic Composite Properties and their Applications
This review examined how fiber compatibility affects the properties of wood-plastic composite materials, which combine natural fibers with plastic matrices for construction and other uses. Developing better bio-composite materials can help reduce reliance on pure plastics that contribute to microplastic pollution.
A Study of Plant-Filled Polymer Composites Based on Highly Plasticized Polyvinyl Chloride
Not relevant to microplastics — this study characterizes the optical, thermal, and mechanical properties of PVC-based composites filled with plant materials (spruce flour, birch flour, rice husk), exploring eco-friendly construction materials without addressing microplastic pollution.
Mechanical Properties of Polypropylene Composites with different Reinforced Natural Fibers – A Comparative Study
This is a materials science study comparing the mechanical properties of polypropylene composites reinforced with five different natural plant fibers; it is not a microplastics research paper.
Experimental Tests on Lightweight Cement Mortar and Concrete with Recycled Plastic Wastes
This paper is not relevant to microplastics research — it tests the mechanical properties of cement mortar and concrete incorporating recycled plastic waste granules as aggregate substitutes, a construction materials engineering study.
Recycling of Polyethylene and Polypropylene Waste to Produce Plastic Bricks
This paper is not primarily about microplastics — it tests whether recycled PE and PP plastic pellets can replace conventional materials in construction bricks, with a focus on mechanical performance rather than pollution impacts.
Valorization of post-consumer plastic packaging into a composite material
This study developed a composite building material from post-consumer mixed plastic packaging waste, providing a higher-value end use that diverts plastic from landfill. Using plastic waste in durable construction products reduces the amount available to degrade into microplastics in the environment.
Non-Wettable Microporous Sheets Using Mixed Polyolefin Waste for Oil–Water Separation
Not relevant to microplastics — this paper describes manufacturing non-wettable porous sheets from recycled polyethylene and polypropylene waste for oil-water separation, focusing on materials recycling rather than microplastic pollution.
The Unique Morphology of Coconut Petiole Fibers Facilitates the Fabrication of Plant Composites with High Impact Performance
This paper is not relevant to microplastics; it investigates the mechanical and structural properties of coconut petiole fiber composites with polylactic acid (PLA) for manufacturing applications.
Recycling of Polypropylene Recovered from a Composting Plant: Mechanical Behavior of Compounds with Virgin Plastic
Not directly relevant to microplastics — this paper investigates mechanical recycling of polypropylene recovered from a composting plant's waste stream, focusing on material properties after reprocessing.
Quantification of microplastics formed during weathering from wood-plastic composites
Scientists found that wood-plastic composite materials (eco-friendly plastics mixed with wood) can release tiny plastic particles called microplastics when they break down from sun and weather exposure. Some products like flowerpots released extremely high amounts of these particles, while others like decking released none at all. This matters because microplastics can potentially harm human health when they get into our environment, water, and food supply.
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.
A Comprehensive Review of Plastic Recycling in the Construction Industry: Challenges and Opportunities in the U.S.
Despite its title referencing plastic recycling in the construction industry, this paper reviews the barriers and opportunities for incorporating recycled plastics into building materials in the United States — not microplastic pollution itself. It examines economic, technical, and regulatory challenges for construction-sector plastic recycling and is only indirectly relevant to microplastics through the lens of reducing plastic waste at source.
“Microplastics and Polymers in Construction Materials: Sources, Fate, and Structural/Environmental Impacts”
This review synthesizes evidence that construction practices generate microplastic particles from polymer additives and recycled plastics during manufacturing, placement, and demolition, presents a sampling framework for detecting construction-derived microplastics, and compares identification methods for characterizing these particles.
Optimization of Asphalt Concrete Performance Using Waste Plastic Bottles (WPB) as a Sustainable Bitumen Modifier: A Comprehensive Rheological and Mechanical Assessment
Not relevant to microplastics — this study evaluates waste plastic bottles as a bitumen modifier to improve asphalt road performance, testing mechanical and thermal properties; it addresses plastic reuse in construction rather than environmental microplastic pollution.
Nanostructured lignin carriers for efficient flame retardant delivery in natural rubber composites
Not relevant to microplastics — this paper describes using bio-based lignin nanocontainers to deliver a flame retardant in natural rubber composites, improving fire resistance and mechanical properties; it does not address microplastic pollution, environmental contamination, or health effects.
An Analysis of the State-of-the-art in Plastic Scrap Recycling Strategies for Construction Components

Utilization of spent coffee grounds as fillers to prepare polypropylene composites for food packaging applications
Researchers used waste coffee grounds as filler material in polypropylene plastic composites to improve sustainability and reduce reliance on virgin plastic. Adding natural biomass waste to plastic formulations can reduce the total plastic content in consumer products, though the composites still produce microplastic fragments during use.
