there is a technology available called thermal depolymerization that can convert some of this into energy. I could never figure out if it was not net positive for the only reason it isn't done. Even if it isn't net positive, if they placed the recycling center near an area with surplus electricity, and melt it down into some fuel on low peaks, I think that would be a positive. Would somebody please tell me if its feasible? https://en.wikipedia.org/wiki/Thermal_depolymerization https://en.wikipedia.org/wiki/Thermal_depolymerization
