ClearEvaluation of Eco-Friendly Hemp-Fiber-Reinforced Recycled HDPE Composites
Researchers developed hemp-fiber-reinforced recycled HDPE composites from postconsumer plastic waste, demonstrating that these sustainable biocomposites can serve as eco-friendly alternatives to conventional wood-plastic composite products.
Performance Spectrum of Home-Compostable Biopolymer Fibers Compared to a Petrochemical Alternative
Researchers compared home-compostable biopolymer fibers to conventional petrochemical alternatives, evaluating their mechanical performance and degradability to assess whether biobased materials can serve as viable substitutes that reduce microplastic pollution.
Economia Circular E Desenvolvimento Sustentável: Compostabilidade, Biodegradação E Inovação Em Biopolímeros E Compósitos Renováveis Para Aplicações Estruturais, Agrícolas E Embalagens
This review paper summarizes research on new plant-based plastics that can break down naturally in the environment, unlike regular plastics made from oil. These eco-friendly materials could replace traditional plastic in food packaging and farming, potentially reducing the tiny plastic particles that end up in our food and water. However, the technology still needs improvements and better waste management systems before these biodegradable plastics can widely replace regular plastics.
Nanocelulosas producidas por un proceso de oxidación no convencional: interacciones y aplicaciones
This study developed cellulose micro/nanofibers from plant cell walls using unconventional oxidation and mechanical processes, producing biodegradable biomaterials proposed as renewable alternatives to petroleum-based plastics that generate microplastic pollution.
Bioplastics against Microplastics: Screening of Environmental Bacteria for Bioplastics Production
Researchers screened environmental bacteria for their ability to produce polyhydroxyalkanoate bioplastics, which are biodegradable alternatives to conventional petroleum-based plastics. Developing efficient bioplastic-producing strains is one strategy to reduce the long-term accumulation of persistent microplastics in the environment.
Nano/Micro Hybrid Bamboo Fibrous Preforms for Robust Biodegradable Fiber Reinforced Plastics
Researchers created strong, eco-friendly composite materials by combining nano- and micro-scale fibers from bamboo, producing a biodegradable plastic alternative with improved mechanical properties. This work contributes to developing sustainable materials that could replace conventional petroleum-based plastics and reduce microplastic generation.
Prospección de uso del género Equisetum como producto biodegradable alternativo al uso de tubos plásticos de beber por succión (pitillos)
This Colombian study explored using hollow stems of Equisetum (horsetail) plants as biodegradable, naturally tubular alternatives to plastic drinking straws. Using plant-based replacements for single-use plastic products can reduce the plastic entering the environment and ultimately forming microplastics.
Future Prospects of Biodegradable Natural Fiber Composites: Innovations and Enhanced Performance in Roofing and Packaging Applications
Despite its title referencing sustainable composites and roofing/packaging, this paper studies the development of biodegradable natural fiber composites (from hemp, jute, and flax) as alternatives to synthetic fiber materials — not microplastic pollution research. It examines materials science for sustainable construction and packaging applications and is not directly relevant to microplastic contamination or human health.
Effect of mulching on soil properties, microbial diversity and activities, and crop yield
Researchers examined mulching materials including plastic films and biodegradable hemp fiber alternatives, finding that plastic mulch leaves persistent microplastic fragments in soil with poorly understood consequences, while plant fiber bio-canvas offers a promising biodegradable substitute for weed control.
Biodegradar para No Contaminar: El Futuro de los Plásticos
This Spanish-language paper reviews the current state of biodegradable plastics as alternatives to conventional polymers, examining the potential for bio-based materials to reduce microplastic formation and marine contamination while meeting functional requirements for packaging and consumer products.
Degradation behavior and environmental impacts of a hemp-containing “eco-friendly” compostable plastic in natural environments
Researchers conducted a field experiment exposing hemp fiber-containing 'compostable plastic' to sandy clay soil and river water for up to 33 weeks to assess its degradation behavior in natural environments. Analyses using electron microscopy, thermogravimetry, XRD, and FTIR showed that the material did not fully degrade under natural conditions within the study period, raising questions about its environmental claims.
Exploring Microorganisms from Plastic-Polluted Sites: Unveiling Plastic Degradation and PHA Production Potential
Researchers screened microorganisms from plastic-polluted sites for their ability to break down conventional plastics and produce a biodegradable alternative called PHA. They identified several bacterial strains capable of degrading synthetic polymers and simultaneously producing this bio-based plastic from waste materials. The study highlights the potential for using naturally adapted microbes from contaminated environments as tools for both plastic cleanup and sustainable material production.
Conversion of low-quality cotton to bioplastics
Researchers converted low-quality cotton fibers unsuitable for textile use into bioplastics as an eco-friendly alternative to petrochemical plastics, demonstrating a method to reduce microplastic contamination by substituting conventional plastics with bio-based materials.
Production of polyhydroxyalkanoate (PHA) biopolymer from crop residue using bacteria as an alternative to plastics: a review
This review examines how PHA, a biodegradable plastic made from crop waste using bacteria, could serve as a sustainable alternative to conventional plastics. While PHA breaks down naturally unlike traditional plastics that fragment into microplastics, challenges remain in making it heat-stable and cost-competitive enough for widespread industrial use.
Prospective Biodegradable Plastics from Biomass Conversion Processes
This review surveys the potential of plant biomass as a source of biodegradable plastic alternatives, covering different types of bioplastics and their production processes. Replacing petroleum-based plastics with biodegradable bio-based materials would significantly reduce persistent microplastic pollution.
Influence of microbial biomass content on biodegradation and mechanical properties of poly(3-hydroxybutyrate) composites
This paper is not about microplastics — it studies how adding microbial biomass (algae and cyanobacteria) to a biodegradable polyester (PHB) accelerates its degradation rate in soil.
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.

This Ecuadorian thesis applied bioeconomy principles to develop biopolymers from domestic organic waste as a substitute for single-use plastics in an urban building. Using locally produced bio-based materials to replace single-use plastics directly addresses the generation of the plastic waste that eventually becomes microplastics.
