Nanostructured lignin carriers for efficient flame retardant delivery in natural rubber composites
Not relevant to microplastics — this paper describes using bio-based lignin nanocontainers to deliver a flame retardant in natural rubber composites, improving fire resistance and mechanical properties; it does not address microplastic pollution, environmental contamination, or health effects.
Enzymatic Preparation and Characterization of Spherical Microparticles Composed of Artificial Lignin and TEMPO-Oxidized Cellulose Nanofiber
Scientists developed a one-pot enzymatic process to create submicron particles from plant-derived materials (lignin and cellulose nanofibers). While focused on bio-based materials rather than plastics, this type of work supports the development of biodegradable alternatives to synthetic microplastic-generating materials.
Lignin-driven valorization of lignocellulosic biomass to functional biochar for advanced wastewater remediation: A review
A study explored how lignin-derived materials from lignocellulosic biomass can be valorized into functional products as a sustainable alternative to petroleum-based plastics. Expanding bio-based alternatives is a key strategy for reducing the production of plastics that eventually become environmental microplastic pollutants.
Nanochitin and Nanolignin: Activity and Effectiveness
This review examines the activity and effectiveness of nanochitin and nanolignin as biodegradable, natural polymer-based alternatives to synthetic plastics in consumer products, motivated by growing awareness of microplastic contamination of marine and terrestrial food chains. Researchers found that chitin and lignin-derived nanomaterials offer promising properties for producing zero-waste, skin-friendly, and environmentally compatible goods that can substitute for plastic-containing products entering the environment as microplastics.

Bio Polymers to Save Human Health and Environment: Chitin and Lignin
This review examines chitin and lignin as bio-based polymer alternatives derived from food and agro-forestry byproducts that could reduce plastic waste within a circular green economy framework. The authors discuss how nano-sized versions of these natural polymers can be used to produce biodegradable products, smart tissues mimicking extracellular matrix structure, and sustainable packaging for medical and cosmetic applications.
Sustainable Lignin-Based Nano Hybrid Biomaterials with High-Performance Antifungal Activity
This paper is not directly about microplastics — it investigates lignin-based nano hybrid biomaterials as antifungal agents against Aspergillus species in agricultural settings, with no connection to microplastic pollution.
Wet-Spun Composite Filaments from Lignocellulose Nanofibrils/Alginate and Their Physico-Mechanical Properties
Researchers developed composite fibers from lignocellulose nanofibrils and alginate, examining how varying lignin content affects the fibers' properties and biodegradability. These bio-based materials represent a sustainable alternative to synthetic plastic fibers, which contribute to microplastic pollution through textile washing and degradation.
Lignin Utilization for the Removal of Microplastic Particles from Water
Lignin extracted from agricultural waste and municipal solid waste was tested as an adsorbent for removing various types of microplastics from wastewater, showing promising results. Using lignin — a widely available and renewable byproduct — for microplastic removal could offer a low-cost, sustainable approach to improving wastewater treatment.
Synthesis and structural design of microspheres comprising cellulose nanofibers and artificial lignin polymer by enzyme-mediated Pickering emulsion templating
