In this lab experience, students carry out an investigation to chemically recycle cups made of polylactic acid (PLA) via depolymerization. First, they hydrolyze the PLA using heat and a strong base in solution. Next, they acidify the resulting mixture to generate a lactic acid solution that may be used as a cleaning product.
