NOVELTY - A composting system comprises stationary, horizontal, cylindrical or largely cylindrical chamber; rotating auger shaft centrally mounted within chamber with discrete transfer arms fitted to auger shaft; external motor/gearbox arrangement which rotates auger shaft; discrete sensor modules for monitoring environmental conditions within chamber; blower system for drawing air through chamber; drainage system for removing liquid from chamber; and microprocessor based device for controlling overall operation of composting system and recording environmental conditions within chamber.    USE - Composting system for onsite processing of organic waste into landscaping material and soil conditioner.    ADVANTAGE - The system converts waste material into useful products; and has internal auger system and chamber which is divided up into distinct stages of decomposition using vertical partitions, thus avoiding re-inoculation of agglomerates in fully composted waste with pathogens.    DETAILED DESCRIPTION - Composting system comprises stationary, horizontal, cylindrical or largely cylindrical chamber, with inlet at one end and outlet at the other end; rotating auger shaft centrally mounted within chamber with discrete transfer arms fitted to auger shaft; external motor/gearbox arrangement which rotates auger shaft; discrete sensor modules for monitoring environmental conditions within chamber; blower system for drawing air through chamber; drainage system for removing liquid from chamber; and microprocessor based device for controlling overall operation of composting system and recording environmental conditions within chamber. The aeration, agitation and transfer of composting material through chamber are performed by transfer arms. The transfer arms have paddle shaped blade where pitch of blade can be adjusted to change rate of transfer. The chamber is partitioned into smaller chambers by number of vertical partition units, each smaller chamber performing distinct phase of decomposition. The auger shaft is rotatable in either direction.
