NOVELTY - The apparatus comprises an elongate process tube having an inlet for receiving processing material (2) and an outlet for processed material, a gas conveying system for fluidically conveying the material through the processing tube, a control system, a separation unit for extracting the process gas from the processing tube, a conveying gas compressor for increasing the pressure of the conveying gas, a fluid outlet for draining fluid, a fluid inlet, and a chamber for thermally treating the process gas produced by the apparatus by heating it so as to breakdown any volatile organic compounds.    USE - The apparatus is useful for processing material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge to gasify or pyrolyze it for producing synthesis gas.    ADVANTAGE - The apparatus is capable of continuously and efficiently processing the material containing large percentage of organic matter.    DETAILED DESCRIPTION - The apparatus comprises an elongate process tube having an inlet for receiving processing material (2) and an outlet for processed material, a gas conveying system for fluidically conveying the material through the processing tube, a control system, a separation unit for extracting the process gas from the processing tube, a conveying gas compressor for increasing the pressure of the conveying gas, a fluid outlet for draining fluid, a fluid inlet, a chamber for thermally treating the process gas produced by the apparatus by heating it so as to breakdown any volatile organic compounds, an outlet conduit for supplying hot process gas to the processing tube for use as the conveying gas, a feed hopper for receiving and temporarily storing material to be processed, a secondary hopper (4) fed by the feed hopper, and sensors to sense the quality of the process gas. The conveying system comprises a supply of conveying gas comprising hot pressurized inert gas, where the supply is connected to the processing tube at its inlet end. The control system is configured to control the supply of the pressurized inert gas to the processing tube so as to convey a batch of the material through the tube, where the material is heated to cause any organic matter to gasify for producing process gas. The processing tube comprises sections of which each is separated by a closure. The gas conveying system includes an inlet associated with each section for the supply of conveying gas to move the material into the next section. An expansion of the conveying gas moves the material in the processing tube. The conveying gas compressor comprises a compression chamber having a piston (20) for receiving the conveying gas, and an actuator for moving the piston in the chamber to compress the gas. The compression chamber is sized such that one stroke of the piston in the chamber expels sufficient conveying gas to convey material from one section of the processing tube to another. Each section of the processing tube has a compressor, and a process gas outlet towards its downstream end. The fluid outlet is provided in each section of the tube. The fluid inlet is provided in conveying gas inlet conduit of each section for feeding fluid into the conveying gas. The secondary hopper is connected to the processing tube by a valve (3), and has a conveying gas inlet at its upper end. If the quality of the process gas does not meet a predetermined criteria, the process gas is recirculated through the processing tube, and if the quality of the process gas does meet the predetermined criteria, a part of the process gasses is extracted for storage or direct use. An interior surface of the processing tube is provided with fixed agitators to promote the tumbling of material within the tube. An INDEPENDENT CLAIM is included for a method for processing material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge.
