ClearAcceleration of Biodegradation Using Polymer Blends and Composites
This review examines how blending biodegradable polymers with other materials can tune both physical properties and biodegradation rates, noting that many biodegradable plastics degrade far more slowly than claimed. The authors stress that biodegradation claims require rigorous validation under realistic environmental conditions.
Enhancing environmmental biodegradation of polyesters
Researchers investigated strategies to enhance the environmental biodegradation of polyester-based packaging polymers, proposing two pathways: a smart material design concept that incorporates degradation-facilitating additives, and an enzymatic approach using engineered polyesterases. The work addresses the practical challenge that biodegradable polyesters degrade too slowly under real environmental conditions, generating persistent microplastic fragments, and aims to close this gap between certified biodegradability and actual environmental breakdown.
Evaluation of the degradation from micro to nanoplastics from biodegradable bags in marine conditions
Researchers evaluated how biodegradable plastic bags degrade into micro- and nanoplastics under environmental conditions, comparing them to conventional plastics. The study found that even biodegradable materials generate persistent micro- and nanoplastic particles under real-world conditions.
Degradation of Biodegradable Single-use Plates and Waste Bags in Terrestrial and Marine Environments
Field experiments found that biodegradable single-use plates and waste bags degraded at very different rates depending on material and environment, with some lasting far longer than expected. Products labeled as biodegradable may still persist and fragment into microplastics in natural marine and terrestrial conditions.
Recent Advances in Bioplastics: Application and Biodegradation
This review examines recent advances in bioplastics — including their applications in packaging, agriculture, and medicine — and critically evaluates their actual biodegradation performance in both natural and industrial environments, finding a significant gap between claims and real-world outcomes.
Enhancing environmmental biodegradation of polyesters
Researchers investigated two pathways for enhancing the environmental biodegradation of polyester-based packaging polymers: a smart additive-based material design concept and an engineered enzymatic degradation approach using optimised polyesterases. The work addresses the gap between the theoretical biodegradability of polyesters like PLA and PBAT and their actual slow degradation in natural environments, which leads to persistent microplastic generation during the end-of-life phase.
Degradation of supposedly biodegradable polymers in a real estuarine environment
Researchers tested the real-world degradation of supposedly biodegradable polymer bags in an estuarine environment over 180 days. The study found that bags made of PLA combined with PBAT and starch showed the most consistent degradation, while polyethylene bags with oxo-biodegradable additives and plain polyethylene showed minimal breakdown, questioning the effectiveness of some biodegradable alternatives in natural settings.
Analysis of the Mechanical Degradability of Biodegradable Polymer-Based Bags in Different Environments
Researchers analyzed the mechanical degradability of biodegradable polymer-based bags under simulated environmental conditions, measuring fragmentation rates and the physical characteristics of resulting particles. The bags fragmented into microplastic-sized pieces under mechanical stress comparable to environmental conditions, raising concerns that biodegradable bags may contribute to environmental microplastic loads during incomplete degradation.
Appraising co-composting efficiency of biodegradable plastic bags and food wastes: Assessment microplastics morphology, greenhouse gas emissions, and changes in microbial community
Researchers tested composting biodegradable plastic bags with food waste and found that while the bags broke down faster than regular plastic, the process still produced microplastic fragments and affected greenhouse gas emissions. The type of additives in the biodegradable bags influenced both the composting process and the microbial communities involved. This study raises important questions about whether "biodegradable" plastics truly solve the microplastic problem or simply create smaller plastic particles during decomposition.
Hazard profiling of compostable shopping bags. Towards an ecological risk assessment of littering
This study conducted ecological risk assessment of littering by compostable shopping bags, finding that while these materials degrade faster than conventional plastics, the additives and degradation products may still pose hazards to soil and aquatic organisms.
Biodegradable plastics in the air and soil environment: Low degradation rate and high microplastics formation
Researchers compared the degradation rates of various biodegradable plastic types in natural air and soil environments over time, finding that most degraded slowly under ambient conditions and generated substantial microplastic fragments, with non-certified biodegradable plastics showing essentially no degradation.
Introduction, Past and Present Scenarios of Plastic Degradation
This review traces the history and current state of plastic degradation research, covering how plastics break down in the environment and what technologies exist to accelerate or improve degradation. The persistence of plastic in the environment is what drives the ongoing accumulation of microplastics globally.
Evaluation of the degradation from micro to nanoplastics from biodegradable bags in marine conditions
Researchers evaluated how biodegradable plastic bags degrade from the micro to nano scale under environmental conditions, testing whether commercial biodegradable plastics fully decompose or generate persistent nanoplastic particles. Results showed biodegradable bags produced nanoplastic particles during degradation, challenging the assumption that biodegradable label guarantees complete environmental breakdown.
Biodegradability standards for carrier bags and plastic films in aquatic environments: a critical review
Researchers critically reviewed existing biodegradability standards for carrier bags and plastic films in aquatic environments and found that current testing protocols do not adequately reflect real-world marine or freshwater conditions. The study suggests that labeling plastics as "biodegradable" may be misleading, since degradation rates vary dramatically depending on temperature, oxygen levels, and microbial communities present in natural water bodies.
Biodegradable plastics in the marine environment: a potential source of risk?
This review examines whether biodegradable plastics offer a genuine solution to marine plastic pollution, finding that their environmental behavior depends heavily on specific conditions and that they may still pose risks in marine environments where decomposition is slow.
Biodegradable microplastics (BMPs): a new cause for concern?
This review examined whether biodegradable microplastics present new environmental hazards, finding that many biodegradable polymers degrade slowly under real environmental conditions and can release toxic additives, and that the assumption of biodegradability does not eliminate microplastic pollution risks unless composting conditions are actively managed.
Novel Acumens into Biodegradation: Impact of Nanomaterials and Their Contribution
This review examines how nanomaterials can enhance the biodegradation of pollutants, including plastics, in the environment. Nanomaterial-assisted biodegradation offers a potential strategy for accelerating the breakdown of plastic waste before it fragments into microplastics.
Polymer Biodegradation and Polymeric Biomass Valorization
This book chapter covers current research on the biodegradation of synthetic and natural polymer waste, including new biotechnology methods for converting plastic materials into useful products. Accelerating biodegradation of plastic waste is one approach to preventing its accumulation and fragmentation into environmental microplastics.

Review on the Biological Degradation of Polymers in Various Environments
This review provides an overview of how biodegradable plastics degrade under different environmental conditions including soil, freshwater, marine, and composting environments. It finds that biodegradability is a material property strongly dependent on environmental conditions, and that many so-called biodegradable plastics degrade far more slowly in nature than in controlled test conditions.
Behind the Green Promise: Eco-Innovation or Commercial Illusion?
This review critically examines the gap between the environmental promise of biodegradable packaging materials such as polylactic acid and polybutylene succinate and their real-world degradation performance. The authors found that most biodegradable plastics require specific industrial composting conditions to degrade as marketed and may perform no better than conventional plastics when disposed of in landfill, soil, or marine environments.
Application of biodegradable plastic and their environmental impacts: A revie
This review examines the environmental impacts of conventional petroleum-based plastics and evaluates biodegradable alternatives made from plant-based and other organic materials. Researchers found that while bioplastics show promise for reducing long-term pollution, their degradation rates vary significantly depending on environmental conditions. The study emphasizes that switching to biodegradable plastics alone is not enough without proper waste management infrastructure.
