Turning technology inside out High-pressure gases exit the gasiﬁer through the syngas outlet and power a turbine, which generates electricity to run the gasiﬁer and sell to energy suppliers. MAY_08 j 48 Municipal waste materials are fed through the waste inlet into a steel reactor vessel called a gasiﬁer, which contains a controlled amount of oxygen or other process gas, such as nitrogen or argon. The plasma gasiﬁer is about 40 feet tall. Plasma torches use electricity and oxygen to create an electric arc. The resultant gas, which is as hot as 10,000 degrees Fahrenheit, is called plasma. TURNING Molten waste is disposed of via the metal and slag output. This matter is cooled and can be used for roadbed materials or construction. GARBAGE
