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.
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.
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.
Nonwoven Fabrics from Agricultural and Industrial Waste for Acoustic and Thermal Insulation Applications
This paper is not relevant to microplastics research — it investigates the acoustic and thermal insulation properties of nonwoven fabrics made from coffee husk fibers blended with cotton and other natural fibers.
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.

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.
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.
Second Life for Plastic Fibre Waste Difficult to Recover: Partial Replacement of the Binder in Asphalt Concrete Mixtures by Dry Incorporation
Researchers found that incorporating waste plastic fibers from municipal solid waste into asphalt concrete as a partial bitumen replacement improved resistance to plastic deformation and mechanical performance, with results approaching those of polymer-modified bitumen mixtures while improving material sustainability.
Exploration of Interior Material Based on Plastic Waste
Researchers explored the potential for plastic waste to be transformed into interior design materials, using observation, interviews, and documentation methods to analyze the process from material collection through fabrication. The study characterized the physical and chemical properties of plastic waste relevant to its use as an interior material and assessed structural strength alongside its environmental risks.
Novel Treatment to Immobilize and Use Textiles Microfibers Retained in Polymeric Filters through Their Incorporation in Composite Materials
Researchers developed a novel method to immobilize textile microfibers captured in polymeric washing machine filters by incorporating them into composite polymer matrices, transforming a waste microplastic stream into a potentially reusable construction or industrial material rather than releasing it to the environment.
Recycling of disposable single-use face masks to mitigate microfiber pollution
Researchers mechanically recycled discarded disposable face masks into polypropylene-cotton blended fabrics, demonstrating an 83% reduction in microfiber release across the product lifecycle compared to masks, though complete elimination of fiber shedding was not achievable due to the inherent properties of textile materials.
Circulatory Management of Polymer Waste: Recycling into Fine Fibers and Their Applications
This review examined technologies for recycling polymer waste into fine, nano-, and microscale fibers via electrospinning and melt blowing, demonstrating that circular management of plastic waste can produce functional materials for filtration, biomedical, and textile applications.

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.
Energy absorption and resilience in quasi-static loading of foam-formed cellulose fibre materials
Researchers investigated lightweight foam-formed cellulose fibre materials as potential replacements for fossil-based plastic cushioning in packaging applications. They tested a wide range of material compositions and densities, finding that fibre type and refining significantly influenced energy absorption and resilience during compression. The study demonstrates that cellulose-based foams could provide adequate mechanical protection for packaging while avoiding the microplastic pollution associated with conventional plastic foams.
Textile solid waste in product development studies
This review covers how textile solid waste — a major and growing global waste stream — is being used in product development studies. Finding new uses for waste textiles could reduce the volume of synthetic fabrics that degrade into microplastic fibers in the environment.
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.
Experimental Investigation of the Influence of High-Frequency Standing Sound Waves on Depth Filtration Using Coarse-Pored Media
This study investigated using high-frequency sound waves to improve depth filtration of fine particles from suspensions. Acoustic filtration enhancement could potentially be applied to improve microplastic removal in water treatment, where current filtration methods sometimes struggle with the smallest plastic particles.

The research demonstrates a practical pathway for diverting microplastic waste from the environment by incorporating it into building materials. Using microplastics as a construction input could help reduce both plastic pollution and the environmental footprint of the construction industry.
