ClearFungal chitosan in focus: a comprehensive review on extraction methods and applications
Researchers reviewed fungal-derived chitosan as a biodegradable plastic alternative for food packaging, highlighting advantages over marine-sourced chitosan — including lower mineral content, year-round supply, and reduced microplastic contamination risk — alongside advances in extraction techniques such as deep eutectic solvents and enzymatic processing.
Optimisation of Chitosan as A Natural Flocculant for Microplastic Remediation
Laboratory tests found that chitosan — a natural, biodegradable material derived from shellfish — can remove 68.3% of microplastics from water using a coagulation-flocculation process, with an optimal concentration of 30 ppm. Higher chitosan doses increased organic matter in the water (COD and BOD), suggesting a trade-off between microplastic removal efficiency and water quality parameters. Chitosan offers a promising eco-friendly alternative to synthetic chemicals for treating microplastic-contaminated water.
Chitosan with Natural Additives as a Potential Food Packaging
Researchers reviewed the potential of chitosan, a natural polymer derived from chitin, as a sustainable alternative to conventional plastic food packaging. Chitosan-based materials combined with natural additives show promising antimicrobial and biocompatible properties while being biodegradable. The study suggests these materials could help reduce plastic packaging waste and the associated microplastic pollution from food industry sources.
Chitosan oligosaccharide-modified Pleurotus ostreatus mycelium for microplastic removal based on the green design concept

The use of chitosan for water purification from microplastics
Researchers investigated chitosan as a sorbent for removing microplastics from water, analyzing its physicochemical properties and proposing an optimized purification method based on chitosan's sorption characteristics.
Sustainable biomaterials based on cellulose, chitin and chitosan composites - A review
Researchers reviewed advances in making sustainable composite materials from cellulose, chitin, and chitosan — abundant natural polymers found in plants and shellfish — as biodegradable alternatives to synthetic plastics that contribute to microplastic pollution. The review covers how these biopolymers can be dissolved and combined into fibers, films, and gels for a wide range of environmentally friendly applications.
A Chitosan Nanofiber Sponge for Oyster-Inspired Filtration of Microplastics
An ultralight chitosan nanofiber sponge was developed as a filtration material for removing microplastics from water, inspired by oyster filtration biology, and demonstrated high removal efficiency for polystyrene microplastics in lab tests while being biodegradable and made from renewable chitosan feedstock.
Utilization of chitosan as a natural coagulant for polyethylene microplastic removal
Scientists tested chitosan, a natural material derived from shellfish, as an eco-friendly way to remove polyethylene microplastics from water. Under the best conditions (pH 6.0 with 100 mg/L of chitosan), the treatment removed 81.5% of microplastics, offering a promising and environmentally safe approach to cleaning microplastic-contaminated water.
Chitosan as a sustainable alternative for fresh food packaging: Structural insights, modification strategies, and innovations for commercial viability
Researchers reviewed how chitosan — a natural biopolymer derived from crustacean shells — can serve as a biodegradable alternative to single-use plastic food packaging, detailing chemical modification strategies, nanocomposite reinforcement approaches, and recent advances in antimicrobial and antioxidant performance that improve its commercial viability.
Exploring the Role of Chitosan in Fabricating Biodegradable Films for Functional Food Packaging: A Review
This review examines the use of chitosan — a biopolymer derived from crustacean shells — in fabricating biodegradable food packaging films, evaluating its mechanical, antimicrobial, and barrier properties as a sustainable alternative to conventional plastics.
Evaluation of the Antimicrobial Activity of Chitosan Nanoparticles against Listeria monocytogenes
Not relevant to microplastics — this is a microbiology study testing the antimicrobial effectiveness of chitosan nanoparticles from different sources against the foodborne pathogen Listeria monocytogenes, finding that nanoparticle size — not just molecular weight or deacetylation degree — drives efficacy.
Recent Research Trends in Mushroom Mycelium-based Materials
This review summarizes recent research on mushroom mycelium as a sustainable industrial material, covering applications in leather substitutes, construction, electronics, packaging, and insulation.

Ingesting chitosan can promote excretion of microplastics
Researchers found that feeding rats chitosan (a natural fiber derived from shellfish shells) along with microplastics significantly sped up the excretion of the plastic particles from their bodies. The chitosan appeared to bind to the microplastics in the gut and help move them out more quickly through the digestive system. This is a promising finding because it suggests that a readily available dietary supplement could help reduce the amount of microplastics that accumulate in the body.
