ABSTRACT:
A method and apparatus of cofiring hazardous organic waste in solid, pasty, greasy or sludge form by introducing it directly into the burning zone of an industrial rotary kiln and burning the waste in the burning zone simultaneously with cement, lime or lightweight aggregate. Specifically disclosed are five exemplary embodiments for introducing the waste directly into the burning zone of the kiln, i.e., (1) through a side opening in the kiln, (2) ballistically, (3) by pre-mixing with a powder or granular material and pneumatically injecting the non-sticky mixture, (4) by shredding steel drums containing the waste and thereafter separating the drum fragments and mixing the remaining waste with powder or granular material (i.e. as in (3) and (5) by pregasification of the waste.
