ABSTRACT This study explores the impact of varying polyvinyl alcohol (PVA) content on degradation behavior and mechanical properties bio‐based polybutylene succinate (BioPBS) composites in water soil environments. Higher PVA significantly accelerates rate, as dissolution creates pores cracks that enhance microorganism penetration. While increased initially improves tensile flexural strength, it reduces elongation at break, leading to a more brittle material. After immersion, with higher exhibit substantial declines strength hardness due absorption structural disruption. For instance, 80% dropped from 55.53 3.22 MPa, decreasing 20 HA. Soil tests revealed an 82.01% weight loss 40 BioPBS/60 after 45 days. These findings demonstrate adjusting allows for precise control over rates, enabling development biodegradable materials tailored diverse applications, including agriculture eco‐friendly packaging.
