Abstract
A method and system decomposes or immobilizes organic wastes using a metal alloy agent comprised of at least two metals selected from transition metals, alkaline metal and/or and rare earth metals. The method first uses hydrogen and oxygen, with and without mechanical agitation, to decrepitate and activate the metal alloy powders. The organic waste compounds are then introduced to the activated metal alloys. This method of decomposing organic materials effectively destroys organic compounds which contain halogens, sulfur, phosphorous, oxygen, and higher order bonds.
