Properties of reclaimed polypropylene microplastic-polylactic acid blends
This study explored whether mixing reclaimed microplastic polypropylene with biodegradable PLA plastic could reduce environmental harm while preserving useful mechanical properties. The blends were tested in seawater and buried in soil to assess biodegradation, and a 90% PP / 10% PLA blend retained the highest tensile strength after seawater immersion. Higher PLA content accelerated biodegradation but reduced thermal stability and strength. The research offers a potential strategy for making recovered microplastic materials more environmentally manageable without sacrificing too much performance.
