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.

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 m3

(process organics during anaerobic and aerobic phases).– Process water tank ~ 600 m3

(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.

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 (55oC) which ensures pasteurisation. Bacterial inoculum transferred back to process water tank at end of stage and maintained for future anaerobic cycles.
