This study developed biodegradable PBAT/lignin composite films reinforced with silane-modified silica nanoparticles, aiming to improve mechanical strength while maintaining UV-blocking properties useful for agricultural film applications. Developing high-performance biodegradable agricultural plastics is important for reducing the plastic mulch that is a major source of microplastic contamination in farmland soils.
Methodology development: evaluation of structural, thermal, and mechanical properties of poly(lactic acid)/poly(butylene adipate-co-terephthalate) blends for biodegradable mulch
Researchers developed a methodology for formulating and characterizing biodegradable PLA/PBAT mulch films as alternatives to conventional polyethylene mulch that contributes to microplastic pollution in agriculture. The proposed approach covers scalable formulation, processing, and comprehensive characterization aligned with regulatory guidelines and industry standards for biodegradable mulch performance.
Effect of the Incorporation of Lignin on Starch/PVA Blend Films Produced by Casting
Researchers produced and characterized starch/PVA blend films incorporating varying amounts of lignin (0%, 0.5%, 1%, and 2%) using a casting method, aiming to improve the mechanical and barrier properties of biodegradable packaging materials. The study identified optimal lignin concentrations that enhance film performance while maintaining biodegradability as an alternative to conventional polymeric materials.
In Situ Constructing Highly Aligned Ribbon-like PHBV Lamellae in PBAT: Towards Strong, Ductile and High-Barrier PBAT/PHBV Films
Despite its title referencing biodegradable plastic film materials (PBAT and PHBV), this paper studies the materials science of fabricating high-performance biodegradable packaging films — not microplastic pollution or health effects. It examines how combining two bio-based polymers with a compatibilizer improves mechanical strength and barrier properties and is not directly relevant to microplastic exposure or human health impacts.
Characterization of Biodegradable Polymers for Porous Structure: Further Steps toward Sustainable Plastics
Four biodegradable polymers -- PBAT, PBS, PHBV, and PLA -- were systematically characterized for mechanical, thermal, and porous structural properties to assess their suitability as more sustainable alternatives to conventional plastics.
Development and Characterization of Poly(butylene succinate‐co‐adipate)/Poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) with Cowpea Lignocellulosic Fibers as a Filler via Injection Molding and Extrusion Film‐Casting
Researchers developed and characterized biodegradable composite films from poly(butylene succinate-co-adipate) and polylactic acid, evaluating their mechanical properties, thermal stability, and compostability. The blended composites showed improved ductility compared to neat PLA and degraded fully under industrial composting conditions, supporting their use as sustainable packaging alternatives.
Study of Hybrid Humic Acids Modification of Environmentally Safe Biodegradable Films Based on Hydroxypropyl Methyl Cellulose
Researchers modified hydroxypropyl methyl cellulose biodegradable films with different types of humic acids from lignite, producing hybrid films with improved mechanical strength and antibacterial properties as a safer alternative to synthetic plastic films.
Development of mulch films from biodegradable polymer and agro-industrial waste
Biodegradable mulch films were developed from poly(butylene-adipate-co-terephthalate) (PBAT) incorporating soybean and peanut hull agro-industrial wastes as alternative to conventional plastic mulches. The agro-waste additives improved film hydrophobicity but increased water absorption values, with mechanical and thermal properties characterized across different formulations.

Deep eutectic solvent-mediated extraction of lignin: A novel strategy for producing high-quality biopolymers in controlled-release mulching applications
Researchers developed a biodegradable mulch film made from lignin, chitosan, and polyvinyl alcohol that can also slowly release fertilizer to crops. The film matched the thermal insulation and water retention properties of conventional plastic mulch while breaking down naturally in soil. The study offers a promising alternative to plastic mulch films, which are a major source of microplastic contamination in agricultural soils.
