Abstract

See full text

A method for identifying and separating hydrophilic plastic from hydrophobic plastic includes tagging the hydrophilic plastic with a tagging agent, such as a fluorescent dye. Upon exposure to a water bath or other processing fluid, the hydrophilic plastic incorporates, such as by absorption, the tagging agent. The plastic containing the tagging agent is then detected and separated from the remainder of the plastic material.
