Microcrystalline cellulose grafted hyperbranched polyester with roll comb structure for synergistic toughening and strengthening of PHBV/ bio-based polyester elastomer composites
Researchers developed fully bio-based composite materials by combining a biodegradable polyester with cellulose-grafted polymer structures, significantly improving the toughness of otherwise brittle bioplastics. Stronger bioplastics could replace conventional plastics in more applications, reducing long-term microplastic generation from plastic products.
Cellulose nanofiber reinforced starch film with pH- responsive weakening and marine-degradability
Researchers developed a starch film reinforced with oxidized cellulose nanofibers that weakens rapidly in seawater due to pH-responsive properties and is degraded by marine microbes. The material lost strength under marine conditions in a controlled and tunable way. This biodegradable alternative to conventional marine plastics could help reduce persistent plastic pollution in ocean environments.

Efficacy of bacterial cellulose hydrogel in microfiber removal from contaminated waters: A sustainable approach to wastewater treatment
Researchers developed a bacterial cellulose hydrogel made from unused cellulose remnants and tested it as an eco-friendly filter for removing microfibers from contaminated water. The hydrogel achieved an average removal rate of nearly 94 percent and retained the captured fibers well, releasing only about 8 percent after washing. The study presents this bio-based approach as a sustainable and effective alternative for tackling microfiber pollution in wastewater.
Influence of microbial biomass content on biodegradation and mechanical properties of poly(3-hydroxybutyrate) composites

Cellulose Nanofibrils Dewatered with Poly(Lactic Acid) for Improved Bio-Polymer Nanocomposite Processing
This paper is not about environmental microplastics; it describes a manufacturing process for combining cellulose nanofibers with polylactic acid (a biodegradable bioplastic) to make stronger composite materials, with no relevance to plastic pollution or human health risk.
High-strength alginate fibers wet-spun from pre-crosslinked sodium alginate solutions
Scientists developed a new method for making stronger alginate fibers from seaweed-derived materials as a biodegradable alternative to petroleum-based synthetic fibers. The resulting fibers had breaking strength of 474 MPa, exceeding most plant-based fibers without additives. Replacing synthetic fibers like polyester with biodegradable alternatives is important because synthetic textiles are one of the largest sources of microplastic pollution through washing and wear.
Bacterial cellulose biopolymers: The sustainable solution to water-polluting microplastics
Researchers developed bacterial cellulose (BC) biopolymer filters as a sustainable alternative to petroleum-based polymer filters used in wastewater treatment plant microplastic removal. BC filters showed high MP capture efficiency and are biodegradable, addressing both microplastic pollution and the environmental costs of conventional synthetic filter maintenance.
Removal of Nanoplastics from Copollutant Systems Using Seaweed Cellulose Nanofibers
Researchers developed biodegradable nanofibers derived from seaweed cellulose that can efficiently remove nanoplastics from contaminated water, even when other pollutants like heavy metals or dyes are present. Both positively and negatively charged versions of the nanofibers achieved high removal rates for polystyrene nanoplastics across a range of water conditions. The study presents an eco-friendly filtration material that could help address the growing challenge of nanoplastic contamination in drinking water sources.

Influence of Green Nanofillers on the Morphological, Mechanical Properties, and Degradation Kinetics of PBS/PBAT Blends: A Potential Sustainable Strategy for Fisheries Applications
Researchers developed biodegradable polymer blends reinforced with nanochitin and nanocellulose — materials derived from natural sources — as a potential replacement for synthetic nylon fishing nets. The bio-based nanofillers improved the mechanical strength and altered degradation rates of the PBS/PBAT blends, bringing performance closer to what is needed for real fishing applications. Replacing synthetic nylon with biodegradable alternatives could meaningfully reduce ghost fishing and the microplastic pollution that comes from fragmenting nets in the ocean.
