" ... As for the chemical component, Buffalo researchers say they’re investigating “environmentally responsible solvents and new chemistries” to help break down plastics and make them easier to reuse, aka chemical recycling. The approach has low greenhouse gas emissions compared to other recycling methods. ... "
" ... For multiple-layers of incompatible plastics, chemical engineers like George Huber of the University of Wisconsin at Madison have devised processes that use a series of liquid solvents to dissolve each individual plastic component, choosing the right solvents to dissolve each individual kind of plastic in sequence. ... "
" ... However, water-lean solvents like EEMPA can significantly reduce both energy and capital costs by about 20%, especially when the solvent is chemically changed to be less viscous (less sticky like water versus honey), in fact, a hundred times less viscous (see figure below). ... "
" ... Methanol, or wood alcohol, is produced from coal, natural gas or renewable feedstocks. For years it has been used as a fuel for transportation and a chemical feedstock for solvents, paints and plastics, and more recently it’s been a carrier for hydrogen for fuel cell technology applications. ...
