Abstract: Sustainable polymers, including biodegradable and recyclable materials, are gaining significant importance across various industries due to concerns over fossil fuel dependency, non-biodegradability, and plastic pollution. This article explores recent advancements in sustainable polymer science, focusing on bio-based polymers, biodegradable alternatives such as PLA and PHA, and innovative recycling techniques that contribute to a circular economy. Biopolymers sourced from plants, marine biomass, and microbial synthesis are reducing reliance on nonrenewable fossil resources, while chemical and mechanical recycling methods enable a closed-loop production process. Additionally, breakthroughs in green chemistry, such as solventfree polymerization and nanotechnology, are optimizing energy-efficient manufacturing processes. Despite challenges such as cost, scalability, and regulatory hurdles, the growing adoption of sustainable polymers in sectors including packaging, automotive, healthcare, and textiles signals progress toward a resource-smart economy. Life cycle assessments underscore the economic viability of these materials, offering insights into the future of sustainable polymers.
