Abstract: An apparatus for the composting of fermentable organic refuse includes a rotating digester tube with a feed auger continuously providing refuse to the tube and a number of discharge outlets at the distal end of the tube. A number of agitating vanes extend along substantially the entire length of the interior of the digester tube, each vane including sections extending parallel to the axis of the tube and sections angled relative to the tube axis to assist in transporting the refuse along the tube. The digester tube is also provided with a number of air tubes extending along substantially the entire length of the tube and connected through a plenum to a blower at the distal end of the tube. Each of the air tubes includes a number of air openings therethrough for providing counter-flow air at each stage of the fermentation process within the tube.
