It takes waste, breaks the molecular bonds between them, and creates nothing more than gas and glass from it.
Plus, it can even create electricity during this, meaning it can sustain itself, and sell power back into the grid.Then the two usher me into the lab, where the gleaming 15-foot-tall machine they’ve named the Plasma Converter stands in the center of the room. The entire thing takes up about as much space as a two-car garage, surprisingly compact for a machine that can consume nearly any type of waste—from dirty diapers to chemical weapons—by annihilating toxic materials in a process as old as the universe itself. 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.
Apparently it's been around for a while, but the people who run the landfills don't like it, so they're trying to block cities from building them.
