A fast, novel, low-cost approach to achieve near 100% LDPE degradation: phanerochaete chrysosporium landfill bioremediation

Shloka Janapaty, California, USA 16-18

Low-density polyethylene (LDPE) poses global problems, and current methods for its remediation are expensive and unsafe. The goal of this study is to rapidly degrade near 100% LDPE. Multiple parameters were studied and investigated before identifying the four most effective independent variables: inoculation with phanerochaete chrysosporium, baking, etching, and the presence of synthetic landfill leachate. The group in which all variables were tested showed a 99.5%–99.9% reduction in LDPE surface area in six days. CO2 production confirmed degradation. Additionally, leachate was significantly remediated over 12 days. Further experimentation demonstrated that this project can be streamlined for industrial viability.
