Name: Aerobic Biodegradation Bioplastics in Agricultural Soil Description: Aerobic biodegradation in soil evaluates the breakdown of bioplastics under oxygen-rich soil conditions by measuring percentage mass loss over time. In this study, seven different bioplastic materials were incubated in natural soil and periodically analyzed to determine their degradation behavior. A biodegradable control material was included to validate the system and distinguish true biological degradation from physical or environmental losses. The degradation percentage (mass loss) reflects the extent of microbial activity on each material, allowing comparison of biodegradation rates and confirming the relative biodegradability of the tested bioplastics under aerobic soil conditions.
