Abstract

According to this invention there is provided a method of processing material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge, the method comprising: attaching a material container cartridge containing material to be processed to a processing chamber; heating the material in a reduced oxygen atmosphere in the processing chamber to produce gas; channeling the gas from the processing chamber to a treatment chamber in which they are heated to destroy any VOC's therein; recirculating gas from the treatment chamber back into the processing chamber; and in a first mode of operation modifying the moisture content of the gas recirculating from the treatment chamber to the processing chamber by passing it through a second material container cartridge containing material to be processed.

A method of processing material such as organically coated waste and organic materials including biomass, industrial waste, municipal solid waste and sludge, the method comprising:

attaching a material container cartridge containing material to be processed to a processing chamber;
heating the material in a reduced oxygen atmosphere in the processing chamber to produce gas;
channelling the gas from the processing chamber to a treatment chamber in which they are heated to destroy any VOC's therein;
recirculating gas from the treatment chamber back into the processing chamber;
and
in a first mode of operation modifying the moisture content of the gas recirculating from the treatment chamber to the processing chamber by passing it through a second material container cartridge containing material to be processed.

An apparatus for processing material such as organically coated waste and organic materials including:

biomass, industrial waste, municipal solid waste and sludge, the apparatus comprising:
a first material container cartridge containing material to be processed;
a processing chamber that receives the first material container cartridge for processing said material therein at an elevated temperature to produce gas;
a treatment chamber for heating the gas so as to destroy any VOC's therein;
a first conduit means between the treatment chamber and the processing chamber for recirculating hot gasses from the treatment chamber to said processing chamber;
a second material container cartridge containing material to be processed;
a second conduit means between the treatment chamber and the processing chamber having the second material container cartridge therein;
control valve means to selectively direct the gasses from the treatment chamber through the first conduit or the second conduit;
and
a controller to modify the moisture content of the gas by selectively diverting it through the second conduit means.
