Plastics significantly contribute to environmental pollution and carbon emissions. Biodegradable plastics have emerged as sustainable alternatives, but limited physicochemical stability hinders their widespread use. Thus, there is growing demand for functional biodegradable materials with adjustable mechanical properties and controllable degradability. In this study, UV-responsive biodegradable PBAT films were developed by incorporating Ca(OH)₂ nanoparticles derived from waste eggshells. PBAT films containing Ca(OH)₂ exhibited improved mechanical properties. Under UV light, the films degraded more effectively, with higher porosity, 10.62% thickness loss, and a carbonyl index of 5.94%. This study demonstrates the potential of the developed material for various plastic products, including mulching films, bags, food packaging, and shipping foams. It shows stability during use and efficient UV-triggered degradation, offering advantages in plastic recycling and sustainable applications.
