Can you process unsorted household waste?

Yes, the front end sorting facility separates all waste streams, recovering clean recyclable resources including glass, steel, aluminium and plastics from mixed municipal solid waste or suitable commercial waste. The sorting process harvests the organic fraction which is then processed in the DiCOM™ bioconversion process, producing biogas and compost.

Based on an un-segregated source of MSW how much diversion from landfill can an AnaeCo™ facility achieve?

Typically, based on Western Australian waste composition, a diversion of 75% or more is possible; depending on markets for recovered recyclable materials.

How does the technology remove glass, grit and other inert contaminants found in organic material?

AnaeCo’s proprietary two stage Wet Density Separation (WDS) process removes glass, grit and other heavy inert materials from organic material prior to biological processing. This removes up to 99% of contaminants with under 5% loss of organic material. The successful removal of contaminants prior to biological processing is a key point of difference and competitive advantage for the AnaeCo™ System. Many other mixed solid waste processing technologies produce inferior compost due to high levels of glass contamination which reduces the options for end users. 

Do you add any chemicals or reagents to the process?

No. The DiCOM™ bioconversion process enhances and accelerates the natural decomposition process through the active management of biological conditions.

How much biogas is generated in the DiCOM™ bioconversion process?

The AnaeCo™ System produces enough biogas to supply all of its own heating and electrical requirements, with surplus green electricity available for export to the grid.

What is the biogas composition?

Typically 60% methane. 40% carbon dioxide

What do you do with the biogas?

The biogas is scrubbed to remove impurities and used on site to generate electricity.

How much electricity is generated by an AnaeCo™ facility?

Typically 1MW for 60,000tpa o MSW (subject to waste composition).

Is this sufficient electricity to run the plant?

Yes. The amount of electricity consumed by the process is (on average) a little less than half of the electricity generated. Waste heat produced during electricity generation is also harnessed to make the process more energy efficient.

What do you do with the organic fertiliser after bioconversion?

It is an excellent and clean compost/organic fertiliser for agriculture, with over 15kg/tonne of nitrogen and other trace elements. Alternatively with a moderate amount of drying it can be used as a clean bio-fuel with properties similar to brown coal.

How much water does the system use?

Very little; less than 140L (subject to waste composition) per tonne of waste processed.

How big can you build the plants?

AnaeCo™ Plants are modular and scalable upwards from 60,000 tpa in 20,000 tpa increments.

How much land is required for an AnaeCo™ Plant?

AnaeCo™ Plants have a very small footprint, requiring around 0.12m2 per tonne of MSW for main plant and buildings or 0.25m2 per tonne of MSW for a complete site incuding roads. The small plant footprint reduces land requirements and makes the technology suitable for transfer station retrofit or greenfield siting in urban locations.

 

What about odour?

The AnaeCo™ System utilises sophisticated methods of odour control using an enclosed bio-filtration system (with inorganic media) enabling all odour to be removed.

Can the bioconversion process operate in cold climates?

Yes. The vessels are fully insulated and protected from the outside environment so the prevailing temperature is not a critical factor.
