I came across this video (French with tiny English subtitles) about this amazing “new” technology that produces electricity, bio-char, “bio-gas”, and “bio-oils” from standard trash.
From the name “Pyrowave”, it might be microwave gasification, aka plasma gasification. Basically superheating the materials via plasma beam, instantly gasifying carbon-based waste and melting everything else into slag.
I’ve looked at several things regarding Plasma Gasification and I can’t find any numbers on how effecient they are. I mean they all mention needing a very high voltage current to maintain the arc. Has anybody seen any numbers for the energy return-on-investment?
Frankly, if the solid slag is inert, and therefor non-toxic (and much smaller volume than before), I’d be happy with this technology at breaking even or at a slight loss for energy out compared to energy in.
