(ZA9806452-A)      Composting system with vertical insulated composting tower with one or more chambers, the base of each chamber being fitted with a plenum (7) and grate (6) through which air is induced and output is daily removed.    Also claimed is a method which includes: (a) inducing low air flow through compost pile using column energy; (b) utilizing high temperature pyro/thermopylic microorganism activity in pile; (c) retaining pile energy above stoichiometric levels by controlling induced air flow; (d) utilizing evolved gas extraction; and (e) maintaining constant biofilm by combined aerobic/anaerobic operation; and removing biomass regularly.    USE -   Composting system suitable for a range of biomass. Daily production rates are up to 100m3 (or 200m3 if accelerated in a 1000m3 chamber; power demand is 10W/m3 for air, 950W/m3 for shredder, and 5W/m3 for controls.    ADVANTAGE -   The biomass requires no agitation, giving lower odour potential, and is low cost. The system filters the odours produced by anaerobic reactions, and can be situated close to urban areas, reducing collection and disposal costs, as well as increasing potential sales of finished products. The insulated pile energy is sufficient to induce draft in excess of requirements. The system maintains an active biofilm which assists the self-filtering process.
