Abstract

This article focuses on evaluating the biodegradability and material properties of reclaimed microplastic polypropylene (mPP) blended with polylactic acid (PLA), a biodegradable polymer, to address environmental concerns related to microplastic pollution. Various mPP/PLA blend ratios were prepared and characterized for mechanical strength, thermal stability, and biodegradation behavior through seawater immersion and soil burial tests. Results indicate that a 90/10 mPP/PLA blend maintains the highest tensile strength while enhancing biodegradability, as evidenced by increased conductivity and salinity in seawater and weight loss in soil over time. The study suggests that blending reclaimed PP microplastics with PLA can produce sustainable materials that balance durability and environmental performance, with implications for reducing microplastic pollution and supporting circular economy initiatives.
