ClearA review on the occurrence and influence of biodegradable microplastics in soil ecosystems: Are biodegradable plastics substitute or threat?
This review examines whether biodegradable plastics are a genuine solution to plastic pollution or may create new problems in soil ecosystems. Researchers found that many biodegradable plastics do not fully break down under natural conditions and may actually fragment into microplastics faster than conventional plastics, potentially posing additional threats to soil health.
The effect of biodegradable plastics on microplastic accumulation and exposure
Researchers developed a comprehensive method to quantify microplastic accumulation from biodegradable polymers in natural environments, examining whether biodegradable alternatives actually reduce plastic loads compared to conventional polymers under real-world outdoor conditions.
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.
Impacts of conventional and alternative plastics on soil ecosystems
This PhD research investigated how conventional and alternative (biodegradable, bio-based) plastics and their leachates affect soil health, plant performance, and soil organisms. While biodegradable plastics degraded faster, leachates from both conventional and alternative plastics caused similar levels of soil toxicity and plant stress in some conditions.

An Indonesian study tested the degradation of biodegradable plastic materials under UV light, sunlight, and soil burial, measuring changes in mechanical properties and surface structure. The research contributes to understanding how biodegradable plastics perform in real-world environmental conditions compared to conventional plastics.
A state-of-the-art review of environmental behavior and potential risks of biodegradable microplastics in soil ecosystems: Comparison with conventional microplastics
This review compares the environmental behavior and risks of biodegradable microplastics with conventional microplastics in soil ecosystems. Researchers found that biodegradable microplastics fragment more readily and their abundant functional groups significantly affect how they transport and interact with other contaminants like heavy metals. The study suggests that biodegradable plastics may pose distinct and potentially underestimated risks to soil health compared to their conventional counterparts.
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.
A progress update on the biological effects of biodegradable microplastics on soil and ocean environment: A perfect substitute or new threat?
This review examines whether biodegradable plastics, often marketed as eco-friendly alternatives, actually break down safely in the environment. The evidence shows that biodegradable plastics often fragment into microplastics rather than fully decomposing, and these biodegradable microplastics can harm soil organisms, marine life, and disrupt nutrient cycles. The findings suggest that simply switching to biodegradable plastics may not solve the microplastic pollution problem and could introduce new environmental risks.
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.
Insights into photoaging behaviors and mechanisms of biodegradable and conventional microplastics in soil
Researchers compared how biodegradable and conventional microplastics break down when exposed to light in soil environments. They found that biodegradable poly(butylene adipate-co-terephthalate) aged faster than conventional polyethylene, with both types developing surface cracks and chemical changes over time. The study provides new insights into how different plastic types weather in soil, which affects their environmental persistence and potential toxicity.
Unravelling the ecological ramifications of biodegradable microplastics in soil environment: A systematic review
Researchers reviewed 85 studies on biodegradable microplastics in soil, finding that when biodegradable plastics fail to fully break down they can disrupt soil structure, nutrient cycling, and microbial life in ways that depend heavily on concentration and plastic type. The review highlights that "biodegradable" plastics are not a simple fix for microplastic pollution in agricultural soils.
Benefits and Drawbacks of Bioplastic as an Alternative of Conventional Plastic towards Sustainable Plastic T
This review examines bioplastics derived from renewable biomass sources (such as corn starch, vegetable oils, and food waste) as sustainable alternatives to conventional petroleum-based plastics, evaluating their benefits and drawbacks across environmental performance, biodegradability, and scalability. The article explores whether bioplastics represent a viable pathway toward more sustainable plastic use given growing concerns over the non-biodegradable nature and resource intensity of conventional plastics.

This study evaluated the biodegradation of bioplastic made from tapioca starch under both laboratory and field conditions, comparing it to conventional synthetic polymers. The starch-based bioplastic degraded significantly faster than petroleum-based plastics, supporting its potential as a more environmentally friendly alternative to conventional packaging materials.
Biodegradable plastics in soils: sources, degradation, and effects
This review examines whether biodegradable plastics are truly a safe alternative to conventional plastics in soil. While they do break down faster, the degradation process releases microplastics and potentially toxic byproducts that can harm soil organisms, reduce plant growth, and disrupt the microbial communities that maintain soil health.
Mechanical, structural, and biodegradability properties of bioplastics from tamarind seed starch
Researchers synthesised bioplastics from tamarind seed starch and characterised their mechanical, structural, and biodegradability properties as a sustainable alternative to synthetic plastics. The study demonstrated that tamarind starch-based bioplastics exhibit adequate mechanical performance and substantially faster biodegradation compared to conventional plastics, reducing the risk of microplastic accumulation in the environment.

A predictive model to assess the accumulation of microplastics in the natural environment
Researchers developed a mathematical model to predict how different types of plastics accumulate as microplastics in the environment over a 100-year timeframe. They found that biodegradable plastics like PBS showed near-zero accumulation potential in soil, while conventional polyethylene persisted almost completely. The model offers a standardized way to compare the long-term environmental impact of different plastic materials and could help inform policy decisions about plastic alternatives.

Researchers compared the effects of conventional non-biodegradable plastic film-derived microplastics and biodegradable film-derived microplastics on soil biological properties, finding that both types altered soil microbial diversity and enzyme activity. Biodegradable microplastics produced distinct effects from conventional plastics, suggesting their environmental impacts should not be assumed equivalent.
A review of the occurrence and degradation of biodegradable microplastics in soil environments
This review evaluates whether the shift from conventional plastics to biodegradable plastics is truly beneficial for the environment, particularly regarding microplastic formation in soils. Researchers found that biodegradable plastics actually form residual microplastics at a faster rate than conventional plastics, and these particles can negatively affect soil properties, microbial communities, and plant growth. The study suggests the environmental trade-offs of biodegradable plastics deserve closer scrutiny.
