Biodegradable polymers have gained significant attention as eco-friendly alternatives to traditional plastics. Derived from renewable resources like plants, animals, and microorganisms, these polymers can degrade naturally, reducing environmental pollution. Common biodegradable polymers include Poly Lactic Acid (PLA), Poly Hydroxyalk Anoates (PHA), and starch-based polymers. Applications range from packaging and textiles to medical devices and tissue engineering. The shift towards biodegradable polymers aims to mitigate plastic waste, decrease greenhouse gas emissions, and promote sustainable development. T his review explores biodegradable polymers with emphasis on their synthesis and applications. Research has led to significant advancements in biodegradable polymer synthesis and applications. Findings from this study revealed that PLA, for instance, has shown excellent biodegradability and biocompatibility, making it suitable for food packaging, disposable cutlery, and medical implants. PHAs, produced by microorganisms, exhibit similar properties to conventional plastics and are used in medical devices, tissue engineering, and packaging. Starch-based polymers have been developed for biodegradable plastics, offering a cost effective and renewable alternative. Studies have also explored blending biodegradable polymers with other materials to enhance mechanical properties and degradation rates. For example, PLA-PHA blends have shown improved toughness and crystallinity. Furthermore, biodegradable polymers have been used in controlled release systems, delivering drugs, pesticides, and fertilizers in a targeted and sustainable manner. Biodegradable polymers offer a promising solution to environmental pollution and sustainable development. With advancements in synthesis and applications, these materials can replace traditional plastics in various industries, reducing plastic waste and promoting eco-friendly practices. Continued research and development are essential to improve performance, scalability, and affordability, ensuring a greener future for generations to come.
