RECYCLING OF PLASTICS BY SOLVENT-TARGETED RECOVERY AND PRECIPITATION (STRAP)
WARF: P220053US02
Inventors: George Huber, Kevin Sanchez-Rivera, Reid Van Lehn, Theodore Walker, Panzheng Zhou
The Invention
UW-Madison researchers have developed a process to recover the components of printed multilayer plastic films. As an example, a film composed of polyethylene (PE), ethylene vinyl alcohol (EVOH), and polyethylene terephthalate (PET) was subjected to a solvent-targeted recovery and precipitation (STRAP) process which uses the selective dissolution of the plastic components guided by thermodynamic calculations of polymer solubility. Before the STRAP process, the films were shredded to sizes
