One facility in Utashinai, Japan, has been doing just that since 2003, using plasma—an electrically induced stream of hot, charged particles—to process up to 220 tons of municipal solid waste a day. Now a bigger and better $425 million plant is scheduled for completion by 2009 in Saint Lucie County, Florida. The operator, Atlanta-based Geoplasma, expects it to generate 160 megawatts of electricity—enough to power 36,000 homes—from a daily diet of trash. At the plant, garbage will be superheated to more than 10,000 degrees Fahrenheit—about the temperature of the sun’s surface—by a NASA-developed plasma torch. Organic components will be gasifed by the heat; the inorga...
