Abstract
An environmental method was developed and optimized to recycle post-consumer polystyrene utilizing green, reusable solvents. This method requires a terpene to dissolve the polymer and heptane for reprecipitation of the polystyrene, with separation of these materials for reuse achieved primarily through filtration and distillation. Multiple terpenes and separation techniques were analyzed to identify the most optimal approach for maximizing separation and percent recovery of the polymer, terpene, and heptane. The recovered materials were characterized using 1H NMR spectroscopy.
