The unchecked accumulation of petroleum-based plastics has triggered a global environmental crisis, characterized by marine debris, microplastic contamination, and high carbon emissions. Biodegradable polymers (BDPs) have emerged as a pivotal solution to mitigate these impacts by offering materials that decompose into non-toxic byproducts through microbial action. This research article explores the development of BDPs, categorizing them into natural, synthetic, and microbially derived types, such as Polylactic Acid (PLA) and Polyhydroxyalkanoates (PHA). It evaluates current advancements in material reinforcement, such as the use of biocompatible fillers and polymer blending to overcome mechanical limitations. The article provides a present perspective on market integration and regulatory frameworks, while highlighting future directions in "smart" responsive polymers and zero-waste circular economies. Ultimately, the transition to BDPs is essential for achieving long-term ecological sustainability.
