The technology involved in plasma gasification, or perhaps more properly plasma arc waste disposal, has been around for about fifty years, but few facilities exist that utilize it to both dispose of waste and create energy, and none are in the United States. That’s about to change.
Geoplasma, part of real estate developer Jacoby Group (same website), has announced that its planned plasma refuse plant in St. Lucie County, Florida is expected to come online by 2011.
Here are the details:Trash Vaporized at 10,000 Degrees
When trash is put into the plasma converter, the 10,000°F heat vaporizes the solid materials, producing a "syngas" consisting mostly of hydrogen and carbon monoxide. This gas is used to turn an electrical turbine; steam generated in the process can be also utilized to generate electricity.
1500 Tons of Trash = 60 MW
Geoplasma’s facility will process some 1,500 tons of garbage a day, and have a net power capacity of 60 MW. In addition to the power generated, the methane emissions from the landfill can be significantly reduced. Geoplasma says that prices for electricity produced from its facility will be on par with natural gas.
