Abstract
A method for processing waste includes low-temperature carbonizing one portion of the waste creating low-temperature carbonization gas and low-temperature carbonization residue. A carbon-rich fraction is separated off from the low-temperature carbonization residue. At least some of the carbon-rich fraction of the low-temperature carbonization residue is supplied as fuel for a support flame for burning another portion of the waste. A plant for processing waste includes a revolving tubular kiln in which a burner is disposed. A low-temperature carbonization drum has an outlet side communicating with a low-temperature carbonization gas line and a separator device for solid low-temperature carbonization residue. A line carries a carbon-rich fraction of the low-temperature carbonization residue from the separator device to the burner.
