I think this has the potential to be really huge, if it is successful. Its a global problem, and Pyro has a local solution. Every major city in the developed world, with a landfill and with green electricity, is going to want one. 

Worth keeping in mind is that silica is a desiccant and Pyro already has the know how to tweak any of their Sillicon reactors to make anhydrous silica...... if that's not what they're already using. 

I hope Pyro can patent the process - anyone with any expertise with plasma torches could copy it. I guess.

Onward and upward :-)
