Abstract:
1. An apparatus for processing material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge, comprising: a rotatable and tiltable furnace having a body portion, a single material entry point and a tapered portion between the entry point and the body portion of the furnace; a drive mechanism configured to rotate the furnace about its longitudinal axis; a system configured to tilt the furnace; an oxidizer apparatus configured to at least partially oxidize volatile organic compounds (VOC) in gases released by processing of the material; a gas analyzer configured to monitor a level of oxygen and carbon monoxide in gas entering and in gas exiting the furnace, and to provide a signal representative of each level, a process control system; and a first passage configured to conduct the gases from the furnace to the oxidizing apparatus; wherein the process control system is configured to control a temperature of the furnace and of the oxidizing apparatus; and to control a process finish time by identifying a completion of processing of the material by identifying leveling of the signals provided by the gas analyzer representative of carbon monoxide and oxygen levels entering and exiting the furnace.
