Advances in Biodegradable Polymers: Synthesis, Properties and Environmental Applications
AI summary Read the abstract
This review pulls together current research on biodegradable plastics made from natural, synthetic, and microbial sources, looking at how they break down and where they could replace conventional petroleum-based plastics in things like food packaging and farming. Since plastic pollution and microplastics are increasingly linked to health concerns, developing materials that break down safely instead of persisting in the environment (and potentially our food and water) matters for reducing our long-term exposure. The paper notes these alternatives still need more research and better regulations before they can be widely used to replace everyday plastics.
Increased apprehension about the environment due to the extensive use of plastics originating from petroleum has led to the development of biodegradable polymers as prospective replacements for several industrial and environmental applications. Biodegradable polymers are important materials for the circular economy and sustainable resource management due to their degradation into environmentally benign products in a controlled manner. This review presents the current state of research on biodegradable polymers, covering their classification, sources, synthesis methods, structural characteristics, physicochemical properties and environmental applications. Biodegradable polymers derived from natural, synthetic and microbial sources are discussed with emphasis on their structural features and their influence on thermal stability, mechanical properties, degradation behaviour and processability. Recent developments in material design and processing include advances in chemical polymerization, microbial fermentation and green synthesis approaches. Their applications in sustainable food packaging, agriculture, wastewater treatment, environmental remediation and eco-friendly consumer products are also examined in relation to the growing need for alternatives to conventional plastics. Biodegradable polymers represent a promising class of sustainable materials with the potential to reduce plastic pollution, improve resource efficiency and support environmental sustainability. Continued research in polymer design, processing technologies, multidisciplinary material development and supportive regulatory frameworks is needed to facilitate their wider industrial application and realize their long-term environmental benefits.

Bio-degradable polymers through green chemistry: advances, applications, and future perspectives
AI summary Read the abstract
This review paper rounds up recent research on making plastics that break down naturally, using cleaner and safer manufacturing methods instead of harsh chemicals and fossil fuels. This matters because everyday plastics that don't degrade are piling up in landfills and oceans, breaking into microplastics that end up in our food, water, and even our bodies — switching to truly biodegradable materials for packaging, medical devices, and consumer products could help cut down that exposure over time. The paper notes that cost and durability challenges still need to be solved before these greener plastics can fully replace conventional ones.

A Comprehensive Review of Biodegradable Polymer-Based Films and Coatings and Their Food Packaging Applications
AI summary Read the abstract
This review covers the development of biodegradable polymer-based films and coatings as alternatives to conventional plastic food packaging. While these bio-based materials reduce long-term environmental pollution, the review notes that they can still break down into microplastic particles under certain conditions. The shift to biodegradable packaging may reduce but not eliminate the food packaging contribution to microplastic pollution and human exposure.
