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.
Acceleration 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.
Multifunctional Application of Biopolymers and Biomaterials
This paper is not about microplastics; it is a broad review of multifunctional applications of biopolymers and biomaterials across medicine, packaging, and engineering.
Materials
This paper reviews advances in nanocomposite and biopolymer-based food packaging materials, noting that microplastic pollution has been detected globally and is a recognized threat to ecosystem and human health. It briefly contextualises microplastics as a motivation for developing biodegradable packaging alternatives, though the primary focus is materials science rather than microplastics research per se.
Recent Preparations and Innovations in the Biodegradable Bioplastics and Biocomposites (A Review)
This review covered recent advances in biodegradable bioplastics and biocomposites as alternatives to petroleum-based plastics, including their preparation methods, properties, and environmental performance. The authors noted that while bioplastics reduce reliance on fossil fuels and potentially decrease microplastic persistence, production costs and performance limitations remain barriers.
