Joseph Longo’s Plasma Converter turns our most vile and toxic trash into clean energy-and promises to make a relic of the landfill

Excerpts from the article:
How It Works: Startech´s trash converter uses superheated plasma-an electrically conductive mass of charged particles (ions and electrons) generated from ordinary air-to reduce garbage to its molecular components. First the trash is fed into an auger that shreds it into small pieces. Then the mulch is delivered into the plasma chamber, where the superheated plasma converts it into two by-products. One is a syngas composed mostly of hydrogen and carbon monoxide, which is fed into the adjacent Starcell system to be converted into fuel. The other is molten glass that can be sold for use in household tiles or road asphalt.
Called plasma gasification, it works a little like the big bang, only backward (you get nothing from something). Inside a sealed vessel made of stainless steel and filled with a stable gas—either pure nitrogen or, as in this case, ordinary air—a 650-volt current passing between two electrodes rips electrons from the air, converting the gas into plasma. Current flows continuously through this newly formed plasma, creating a field of extremely intense energy very much like lightning.
The radiant energy of the plasma arc is so powerful, it disintegrates trash into its constituent elements by tearing apart molecular bonds. The system is capable of breaking down pretty much anything except nuclear waste, the isotopes of which are indestructible. The only by-products are an obsidian-like glass used as a raw material for numerous applications, including bathroom tiles and high-strength asphalt, and a synthesis gas, or “syngas”—a mixture of primarily hydrogen and carbon monoxide that can be converted into a variety of marketable fuels, including ethanol, natural gas and hydrogen.
Perhaps the most amazing part of the process is that it’s self-sustaining. Just like your toaster, Startech’s Plasma Converter draws its power from the electrical grid to get started. The initial voltage is about equal to the zap from a police stun gun. But once the cycle is under way, the 2,200˚F syngas is fed into a cooling system, generating steam that drives turbines to produce electricity. About two thirds of the power is siphoned off to run the converter; the rest can be used on-site for heating or electricity, or sold back to the utility grid. “Even a blackout would not stop the operation of the facility,”
