Two regimes of vertical shaft furnace operation can be employed to slag encapsulate hazardous chemical wastes. One of these is similar to a method applicable to radioactive wastes, involving the pouring of hot molten slag from a coal reactor over the hazardous matter contained in a suitable designed crucible. The other method is especially appropriate for the treatment of chemical wastes that have become mixed with a great deal of soil or other diluent as must be handled as in the case of the love canal incident. It consists of feeding the contaminated solid mass into the coal reactor with a predetermined amount of coal and limestone that will still admit an adequate heat balance to generate a carefully tailored slag to incorporate the reacted waste feedstock.
