The Plasma Converter ... can consume nearly any type of waste from dirty diapers to chemical weapons by annihilating toxic materials in a process ... called plasma gasification. A 650-volt current passing between two electrodes rips electrons from the air, converting the gas into plasma. 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 only by-products are an obsidian-like glass [and] 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 its self-sustaining. Once the cycle is under way, the 2,200F 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. New York City is already paying an astronomical $90 a ton to get rid of its trash. According to Startech, a few 2,000-ton-per-day plasma-gasification plants could do it for $36. Sell the syngas and surplus electricity, and you'd actually net $15 a ton. But the decision-making bureaucracy can be slow, and it is hamstrung by the politically well-connected waste-disposal industry. Startech isn't the only company using plasma to turn waste into a source of clean energy. A handful of start-ups - Geoplasma, Recovered Energy, PyroGenesis, EnviroArc and Plasco Energy, among othershave entered the market in the past decade.

Each news summary is created according to strict standards. Here's how we do it.
Each summary is created using a consistent editorial procedure. The target length is approximately 16 lines of 11-point Arial text in a 650-pixel-wide column. Up to 25% of a summary may be set in bold to emphasize the most important ideas. Summaries are composed of verbatim excerpts presented in the same sequence as they appear in the original news source, with very minor editorial additions. Where material has been omitted between excerpts, the omission is indicated with ellipses (...). Any words added by an editor for clarity or context appear in [brackets]. Our original news editor was Fred Burks. Tod Fletcher edited most summaries from 2007 through 2014, and Mark Bailey has served as news editor since 2014.
