Biodegradation Studies of Polyhydroxybutyrate and Polyhydroxybutyrate-co-Polyhydroxyvalerate Films in Soil
Researchers studied the biodegradation properties of two bioplastic polymers, polyhydroxybutyrate (PHB) and polyhydroxybutyrate-co-polyhydroxyvalerate (PHBV), in soil under different moisture conditions. Both polymers degraded completely in fully saturated soil, with the study tracking changes in appearance, chemical signatures, mechanical properties, and molecular weight, supporting these materials as viable biodegradable alternatives to conventional petrochemical-derived plastics.
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.
Copolymers and Blends Based on 3-Hydroxybutyrate and 3-Hydroxyvalerate Units
This paper is not about microplastics. It reviews the biodegradable biopolymer PHBV (poly(3-hydroxybutyrate-co-3-hydroxyvalerate)), covering its production, properties, degradation behavior, and applications in various sectors. While PHBV is studied as a potential biodegradable alternative to conventional plastics, this paper focuses on polymer science and materials engineering rather than microplastic pollution.
Recent Developments in Synthesis, Properties, Applications and Recycling of Bio-Based Elastomers
This review covers recent advances in creating elastomers (flexible rubber-like materials) from renewable biological sources instead of petroleum, including natural rubber, plant oils, and bio-based polyurethanes. Current elastomers are mostly non-recyclable thermosets that take centuries to decompose, contributing to microplastic formation as they slowly fragment. Developing bio-based, recyclable alternatives could help reduce the long-term generation of microplastic pollution from rubber and flexible plastic products.
Properties and Degradation Performances of Biodegradable Poly(lactic acid)/Poly(3-hydroxybutyrate) Blends and Keratin Composites
Researchers tested biodegradable blends of polylactic acid and polyhydroxybutyrate with added keratin waste as fillers, assessing how well the composites degrade. The work contributes to developing plastic alternatives that break down in the environment rather than persisting as microplastics.
Biodegradable Elastomers: Where Is the Solution?
Despite its title referencing biodegradable elastomers, this paper reviews the development of sustainable rubber-like polymer materials as alternatives to conventional synthetic rubbers — not microplastic pollution. It examines the chemistry of bio-based and degradable elastomers and is not specifically relevant to microplastics or human health, though reducing persistent synthetic rubber in consumer products could have long-term environmental benefits.
Valorization of agro-industrial waste from the cassava industry as esterified cellulose butyrate for polyhydroxybutyrate-based biocomposites
This study produced biodegradable biocomposites from cassava pulp microcrystalline cellulose and in-house synthesized polyhydroxybutyrate (PHB) biopolymer. The cassava agro-industrial waste-based materials offer a sustainable alternative to petroleum-based plastics for packaging applications, with the potential to reduce environmental microplastic accumulation.
Biobased poly(3-hydroxybutyrate acid) composites with addition of aliphatic polyurethane based on polypropylene glycols
This study developed biodegradable composites by blending poly(3-hydroxybutyrate), a natural bioplastic produced by bacteria, with aliphatic polyurethanes to improve its mechanical properties and thermal stability. Improving bioplastic performance is important for replacing conventional petroleum-based plastics that persist in the environment.
Characterization of PHB/Clay Biocomposites Exposed to Degradation in an Aquatic Environment
This study examined how bioplastic composites made from poly(3-hydroxybutyrate) (PHB) and clay degrade in water. Adding clay altered the degradation rate, and the type of clay (natural vs. organically modified) had different effects — important for designing biodegradable plastics that break down predictably in aquatic environments.
Biodegradable Composites Based on Fossil Types of Raw Materials. Part Ii: the Process of Biodegradation (review)
This review (Part II) examines the biodegradation processes of composite materials made from conventional fossil-based plastics and biodegradable components.

Characterization of Poly(3-hydroxybutyrate) (P3HB) from Alternative, Scalable (Waste) Feedstocks
This study compares two biodegradable bioplastics (P3HB) made from waste feedstocks — one produced by cyanobacteria using sunlight and CO2, the other by methane-eating bacteria — and finds both have thermal and mechanical properties on par with conventionally produced P3HB. The relevance to microplastics is indirect: switching to genuinely biodegradable plastics made from waste gases could reduce the long-lasting microplastic particles generated by conventional petroleum-based polymers.
Natural Deep Eutectic Solvents for PHB Recovery: Mechanistic Insights and Implications for Sustainable Downstream Processing
This study examines recovery methods for polyhydroxybutyrate (PHB), a biodegradable plastic alternative, with a focus on replacing toxic chlorinated solvents with green and natural deep eutectic solvents; PHB is relevant to microplastics research because switching from conventional plastics to PHB would reduce the long-lived microplastic fragments that accumulate in the environment. The paper provides quantitative comparisons of extraction yields and solvent recyclability to guide more sustainable PHB production at scale.
