ClearPermeable pavement blocks as a sustainable solution for managing microplastic pollution in urban stormwater
Researchers tested whether permeable pavement, the kind of pavement that lets water drain through it, can filter out microplastics from urban stormwater runoff. They found it can trap microplastic particles effectively, suggesting permeable pavement could be a practical tool for reducing the amount of microplastics that wash into rivers and oceans from city streets.
Removal and fate of microplastics in permeable pavements: An experimental layer-by-layer analysis
Researchers tested permeable pavements as a way to capture microplastics from urban stormwater runoff and found they retained 89% to over 99% of microplastic particles. The microplastics accumulated mainly on the pavement surface and in geotextile filter layers, preventing them from reaching natural waterways. This type of sustainable urban drainage could be an effective tool for reducing the amount of microplastics that wash off roads and into the water sources people depend on.
Simultaneous Removal of Organic Pollutants and Pathogens from Stormwater by an Enhanced Ecological Gabion
Scientists developed an improved storm drain filter system that removes harmful chemicals and disease-causing bacteria from stormwater runoff much better than traditional systems. The new design uses special materials like biochar along with plants to clean polluted water before it reaches rivers and lakes that people use for drinking water and recreation. This could help protect public health by preventing contaminated stormwater from spreading pollution and germs into our water sources.
Application of Porous Concrete Infiltration Techniques to Street Stormwater Inlets That Simultaneously Mitigate against Non-Point Heavy Metal Pollution and Stormwater Runoff Reduction in Urban Areas: Catchment-Scale Evaluation of the Potential of Discrete and Small-Scale Techniques
This is a civil engineering review on using porous concrete in stormwater inlets to reduce runoff and filter heavy metals in urban areas; it is not a microplastics research paper.
Utilization of Plastic Waste in Interlocking Paver Blocks for Sustainable Pavement Construction
Researchers found a way to turn plastic waste into strong concrete blocks for roads and walkways by mixing shredded plastic pieces with regular concrete ingredients. The plastic-concrete blocks were just as strong as normal concrete blocks, offering a promising solution to reduce the mountains of plastic waste that pollute our environment. This approach could help tackle two major problems at once: getting rid of plastic trash that can break down into harmful microplastics, and reducing the need to mine natural materials for construction.
Eficiencia de los pavimentos permeables para la retención de microplásticos de la escorrentía urbana
Researchers evaluated the effectiveness of permeable pavements as sustainable urban drainage systems for retaining microplastics from urban stormwater runoff, testing their performance under controlled laboratory conditions calibrated to average rainfall patterns in Valencia, Spain. Results showed a significant reduction in microplastic particle counts in water passing through the permeable pavement layers.

Contaminants in Urban Stormwater: Barcelona case study
Researchers analyzed contaminants in urban stormwater runoff in Barcelona, examining dissolved organics, metals, nutrients, and microplastics to assess risks to environmental and public health as cities consider stormwater as a potential groundwater recharge source.
Long-term environmental performance of precast slabs in permeable pavements: hydraulic functionality and pollutant retention in a real-life installation
Researchers assessed the long-term environmental performance of precast permeable pavement slabs in a real-world installation, finding that accumulated contaminants including microplastics build up within the porous structure over time. The study highlights the dual role of permeable pavements as both stormwater management infrastructure and a potential reservoir for pollutants requiring periodic maintenance.

Utilization of plastic waste as replacement of natural aggregates in sustainable concrete: effects on mechanical and durability properties
Researchers tested concrete made with recycled polyethylene and PET plastic aggregates substituted for natural sand and gravel, finding that while plastic additions reduced compressive strength and increased water permeability, they improved impact resistance and chloride resistance, with PET concrete showing no microplastic leaching.
Pavement wear generates microplastics in stormwater runoff
Researchers conducted a two-year field study showing that pavement wear is a distinct and previously underappreciated source of microplastics in urban stormwater, separate from tire wear. They found that asphalt pavement was most susceptible to degradation in the field, while recycled rubber pavers released the most microplastics in lab testing. The study emphasizes the need to consider microplastic generation during pavement material selection and urban infrastructure planning.

A Review on the Application of Granular Filter Media and the Utilization of Agro-industrial Wastes for Stormwater Quality Improvement
This systematic review found that granular filter media including sand, biochar, and agro-industrial waste materials effectively remove heavy metals, nutrients, and suspended solids from stormwater runoff. Agricultural waste materials like coconut coir and rice husk showed promising performance as low-cost filter alternatives. These filtration approaches are relevant to microplastic pollution because stormwater is a major transport pathway for microplastics from urban surfaces to waterways, and granular filters can potentially capture microplastic particles.
