my beef with the issue is there are plenty of places that don't even recycle.
Specifically with electronic waste, it is economical to mine it for copper, gold, silver, lead, antimony, silicon, aluminum etc using traditional metal extraction techniques. the waste is plastic, burn it and sell the HCL that ends up in the scrubber. Or, don't bother collecting the metals, just turn it all into glass. 5 cents/ pound will pay for the energy required. let our kids develop ways to cost effectively remove the metals from said glass, by that time the copper mines will be down to 1% ore anyway.
Plasma gassification isn't cost effective because there isn't any energy in the trash to be had. you have to add heat to get it to burn above 400-500 degrees, about where cardboard burns at. (why are we putting cardboard out with the general refuse rather than recycling it in the first place?
Plastics don't really burn because we mandated PEBD's or whatever the acronym is. Yet the levels aren't even high enough to cost effectively collect the Bromine, even when the trash is entirely pink foam.
etc, etc.
plasma is just a way of making it smaller. (so would compacting it down at 9000 PSI, (would probably be cheaper to...)
