Abstract
Disclosed is the use of residual matter and/or waste as useful materials in electric low-shaft furnaces, said residual matter and/or waste being utilized for heating and/or as a carbon source. The low-shaft furnace used generally comprises a cover as well as at least one hollow electrode for introducing the starting materials. The residual matter and/or waste can be trash, industrial residues, or organic residue and refuse that is difficult to dispose of, such as medicaments, electronic scrap, high-calorie materials, and/or materials that pose a health hazard and can be halogenated. Said residual matter and/or waste preferably has a maximum particle diameter of 100 mm and is introduced particularly in a compact or extruded form into the furnace bed via the hollow electrode. Up to 95 percent of the residual matter and/or waste are converted into pyrolysis gases at furnace temperatures ranging from 1700 to 2500<SUP>o</SUP>C, and the obtained carbon is used as a carbon source, thus making it possible to significantly reduce the amount of energy required for producing calcium carbide, ferrosilicon, ferrochromium, etc.
