For electronics, I've watched some online videos explaining commercial shredding operations and some home based scrapper videos showing how they strip insulation from common household electrical wiring.
I fail to see how either shredding or compression-stripping methods can be used for net environmental benefit in recycling ribbon cables, string lights, etc.
Yet a local electronics recycling operation accepts string mini lights, the kind typically used as xmas decoration.
Edit: After manually removing the interior computer cables (seen in video), how does the facility separate the insulation from the conductor and is there a net environmental benefit? or do they send them to the landfill?
