摘要

Waste composting tower comprising an internal riser tube with a spiral conveyer that continuously re-circulates solids, is new. Waste composting tower comprises an internal riser tube with a spiral conveyer that continuously re-circulates solids, where the tower base is funnel-shaped. An internal tube (13) parallel to its axis and fastened to the top cover (6), is open at its base. Similarly-parallel to the axis, a spiral (14) is located with slight spacing, within the internal tube. It is rotated by its own drive unit (15) on the top cover. An Independent claim is included for the method of composting. The central spiral and tube, raise and recirculate the solids in the tower, in the manner of a spiral conveyor.
