Electricity to be Generated From Garbage Landfills Using Plasma

Ovidiu Sandru — Wed, 12 Nov 2008 18:33:49 +0000

Unlike incinerators, which use combustion to break down garbage, there is no burning, or oxidation, in this process. The heat from plasma converters causes pyrolysis, a process in which organic matter breaks down and decomposes. Plasma torches can operate in airtight vessels. Combustion requires oxidization; pyrolysis does not.
