3. Introduction to AnaeCo Founded in 1999 AnaeCo (ASX:ANQ) is a publicly listed Australian waste technology designer and provider of advanced waste treatment systems based on patented AnaeCo™ solutions. The AnaeCo™ System combines proven: –Material recovery, –Anaerobic digestion, and –Aerobic composting processes. With the objective of recovering maximum value from municipal solid waste (MSW) by: –Recycling precious commodities, –Diverting waste from landfill, –Producing quality organic fertiliser, and –Generating renewable energy.

7. 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.

8. 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.

9. 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.
