Analysis of Bioplastics Derived from Various Microalgae Species

AJAS · 2024

Grace Leavitt · New Jersey Academy of Science

Overview

Each year, the world generates about 300 million tonnes of plastic waste. Sixty percent of the waste culminates in our natural environment or landfills. The plastics never fully decompose, and negatively impact the ecosystem they exist indefinitely within. This study attempted to find an alternative for single-use plastic by developing biodegradable bioplastics from microalgae: Porphyridium cruentum, Chlorella vulgaris, and Isochrysis galbana. After months of creating the bioplastics through a trial and error process, their mechanical properties were tested. The project resulted in bioplastics that are strong, elastic, cost efficient and biodegradable. Almost every aspect of the bioplastics were comparable to commercial plastics. Bio-based and biodegradable plastics are the sustainable direction the world should be moving in.
