DiCOM™ Bioconversion Hybrid biological process which integrates both aerobic and anaerobic (thermophilic) bioconversion cycles in a single digester vessel. Patented process that creates a unique environment for the microbial population resulting in accelerated conversion of organic material to produce stabilised quality organic fertiliser and biogas in a 21 day cycle. The main components of the Bioconversion Facility are: –DiCOM™ vessel ~ 1000 m 3 (process organics during anaerobic and aerobic phases). –Process water tank ~ 600 m 3 (storage of the anaerobic microbiology - ’inoculum’ ). –Screw feed conveyors and de-watering presses (for input, output and handling of organic material to and from the DiCOM vessels). –Odour Management & Biogas processing systems. –Safety Instrumentation System.

S1 DiCOM™ Aerobic Stage 1 ~ 5 Days - Vessel loading ( up to ~ 700 t) of cleaned organic from MRF via conveyor and aerobic processing using patented pressurised (~ 28 kPa) aeration method, during which the temperature of the organic material elevates ready for the high temperature anaerobic stage. Headspace purged with Nitrogen before transition to next stage.

S2 DiCOM™ Anaerobic Stage 2 ~ 11 days - Anaerobic Processing with bacterial inoculum transferred from process water tank to digester vessel and maintained at thermophilic temperature range (55 o C) which ensures pasteurisation. Bacterial inoculum transferred back to process water tank at end of stage and maintained for future anaerobic cycles.
