Researchers evaluated plastic microfiber waste as a sound absorption material, finding it shows some acoustic performance potential. While focused on acoustic engineering, the study explores a possible end use for recycled plastic fiber waste that would otherwise contribute to microplastic pollution.

Researchers evaluated waste tyre textile fibre (WTTF)-based additives as a replacement for cellulose fibres in stone mastic asphalt mixes, finding that 100% replacement met design and performance requirements, offering a sustainable approach to recycling end-of-life tyre by-products in road construction.
Investigation of the sound-absorbing performances of pure coffee grounds
This study tested pure coffee grounds as a natural, eco-friendly sound-absorbing material. Researchers found that coffee grounds had meaningful sound absorption properties, particularly at higher frequencies. Repurposing coffee waste as a building material could substitute for petroleum-based foam sound absorbers that can shed microplastics.
Acoustic and thermal characterization of a novel sustainable material incorporating recycled microplastic waste
Researchers created a new eco-friendly foam material by embedding recovered marine microplastics into a bio-based matrix, producing an open-cell insulating material with strong acoustic and thermal properties. The innovation offers a potential path to upcycle hard-to-recycle mixed marine plastic waste into useful building and industrial insulation products.

Researchers investigated additive-free cold calendering of end-of-life tire rubber powders across three particle size fractions, finding that the finest fraction (<0.5 mm) achieved the highest crosslink density and superior mechanical properties, demonstrating a competitive recycling approach with reduced energy consumption relevant to addressing tire rubber microplastic concerns.
A Practical Valorization Approach for Mitigating Textile Fibrous Microplastics in the Environment: Collection of Textile-Processing Waste Microfibers and Direct Reuse in Green Thermal-Insulating and Mechanical-Performing Composite Construction Materials
Researchers proposed and demonstrated the direct collection and reuse of textile finishing waste microfibers as reinforcement in thermally insulating composite construction materials, diverting a significant fraction of Italy's estimated 5000 tonnes per year of textile processing waste fibers from environmental release. The composite materials met performance benchmarks for construction applications, offering both environmental and economic benefits.
A sustainable acoustic customization of open porous materials using recycled plastics
Researchers developed a sustainable foamy acoustic material by incorporating recycled marine microplastic waste — polyethylene terephthalate (PET) and polystyrene (PS) — into a bio-based matrix, characterizing samples of different compositions for sound absorption and thermal insulation properties.
Assessment of the Environmental Impact of Solid Oil Materials Based on Pyrolysis Oil
This study evaluated building materials made from pyrolysis oil derived from used car tires, finding potential for use in construction. Pyrolysis offers a way to permanently remove waste rubber and plastic from the environment, preventing their fragmentation into microplastics.
Acoustical Characterization and Modeling of Sustainable Posidonia Fibers
Acoustic characterization of loose Posidonia oceanica fiber balls found on Mediterranean beaches revealed their potential as eco-sustainable sound-absorbing materials, with experimental measurement of airflow resistivity and absorption used to derive an analytical Johnson-Champoux-Allard acoustic model.
Effects of tire wear particles on the water retention of soils with different textures in the full moisture range
Tire wear particles added to soils at concentrations of 1-16% by weight reduced soil water retention capacity across multiple soil textures, suggesting that tire-derived microplastic pollution may impair the hydrological function of contaminated soils.
Valorization of textile waste: non-woven structures and composites
This review explores how textile waste -- millions of tons discarded annually -- contributes to pollution in air, water, and soil, even when disposed of in landfills. The paper discusses ways to repurpose waste textiles from materials like polyester and nylon into useful products for construction, insulation, and agriculture. This is relevant to microplastic concerns because synthetic textiles are one of the largest sources of microfiber pollution, and finding ways to recycle them reduces the microplastics released into the environment.
Method for Identification of Black Microplastics by Using Tire Library
This study developed a tire rubber library to improve identification of black microplastics — tire and road wear particles — using FTIR spectroscopy, which struggles with carbon black-containing materials. Tire particles are a major and often undetected category of microplastic pollution in urban runoff.
Studies on the Thermochemical Conversion of Waste Tyre Rubber—A Review
This paper is not about microplastics in a direct environmental-health sense; it is a technical review of pyrolysis and gasification methods for recycling waste tyre rubber to recover carbon black, oil, and syngas — though tire rubber is recognized as a source of environmental microplastics.
Analytical Investigation of Tire Induced Particle Emissions
This automotive engineering study measured the size distribution of fine dust particles (under 10 micrometers) generated by tire wear, finding that tire-derived particles represent a significant non-exhaust source of urban particulate matter. As electric vehicle adoption reduces exhaust emissions, tire and brake wear particles will become a proportionally larger component of urban air pollution. These tire wear particles are also a major source of microplastic contamination in road runoff.

Researchers characterized the engineering properties of waste badminton string fibers, finding that used fibers retain sufficient mechanical strength for potential reuse as reinforcement in cement and polymer composite matrices.
Textile Waste in Civil Construction: A Systematic Review of Applications and Benefits
This systematic review evaluated the use of textile waste in civil construction materials, finding that recycled textile fibers can improve the mechanical properties of composites like concrete and mortar. Repurposing textile waste into construction materials could help reduce the volume of synthetic fibers that otherwise degrade into microplastics in the environment.
Classification and Characterization of Tire-Road Wear Particles in Road Dust by Density
Tire-road wear particles were classified and characterized by density using road dust from an asphalt pavement, allowing separation of tire tread-derived particles from road surface and mineral components. The density-based classification approach improves the accuracy of tire wear particle quantification in environmental monitoring studies.

Tire wear particles in different water environments: occurrence, behavior, and biological effects—a review and perspectives
This review examines tire wear particles, a major but often overlooked source of microplastics in water environments. Tire particles release toxic chemicals as they break down in water and can harm aquatic organisms, but most research has focused only on the chemical leachate rather than the particles themselves. Since tire wear contributes a large share of total microplastic pollution, understanding its full impact on water ecosystems and the food chain is important for human health.
Fate of recycled tyre granulate used on artificial turf
Researchers reviewed the environmental fate of recycled tyre rubber granulate used as infill on artificial turf fields, finding that while the material provides significant CO2 savings compared to alternatives, dispersal of approximately 3,000-5,000 kg per field per year to surrounding environments raises microplastic pollution concerns.
