ABSTRACT:
A method of continuously carbonizing a mixture of primarily organic waste material wherein a stream of comminuted waste material with a substantial organic material content is fed to one end of a mixer barrel, the material is compressed to form a barrel filling mass functioning as a first vapor block, and the work energy required to compress it and squeeze out entrapped air is used virtually exclusively to maintain the temperature of the material adiabatically, air and any steam created are vented, the material downstream from the first vapor block is decompressed in a second vent region, the material is recompressed in the absence of air to form another vapor block, while exclusively utilizing the work energy required to compress it to maintain the temperature of the material adiabatically at volatile releasing and carbonizing temperatures, the volatiles are vented, and the product is discharged as a dry, friable particulate char.
