Abstract
A method is described for environmentally sound usage of combustible hazardous waste in an operating rotary kiln. The method is particularly adapted for disposal of solid hazardous wastes, optionally in the form of a blended waste homogenate, packaged in sealable containers. The containers are used as fuel modules and charged into a rotary kiln cylinder where kiln gas temperatures range from about 950.degree. to about 1200.degree. C. to achieve high destruction and removal efficiencies.
Claims20
A method for achieving environmentally sound disposal of hazardous waste in an operating rotary kiln comprising a heated, rotating cylinder containing in-process mineral material, said method comprising the steps of packaging said hazardous waste in containers and charging the containerized hazardous waste into the kiln to contact the mineral material at a point along the length of the kiln cylinder where the kiln gas temperature ranges from about 950.degree. C. to about 1200.degree. C.
An improved method for recovery of energy values from hazardous wastes in an operating rotary kiln comprising a heated, rotating cylinder containing mineral material, said method comprising the steps of packaging said hazardous waste in sealable containers and charging the containerized hazardous waste into the kiln to contact the mineral material at a point along the length of the kiln cylinder where the kiln gas temperature ranges from about 950.degree. C. to about 1200.degree. C.
