Yes! This is one of the ideas I’ve spent time on and am still somewhat curious about.
InEnTec is the leading company in the space (as far as I can tell) because they have good scientific leadership, a good academic pedigree, and an investment by Waste Management.
The technology still has its challenges. It is hard to make it economical relative to alternatives, for one. I also think executives are not driving at the correct business model, overemphasizing syngas production and underemphasizing just getting rid of waste and possibly recovering metals.
But the biggest problem I see in terms of its viability for recycling is that it is all down cycling. Valuable and precious metals all end up in either a hugely challenging mixed alloy, or they get wasted in the vitrified slag output.
I have been trying to find someone who can clarify if any progress has been made on this.
