ABSTRACT:
The invention is directed to a method for treating an aqueous waste material in order to reduce the volume of the material for disposal and/or landfill. In the method, an aqueous waste material containing organic compounds is contacted with calcium carbide under conditions which cause water and calcium carbide to react to produce acetylene and a residue. The acetylene is burned in the presence of the residue to further reduce the volume of material for disposal.
