Intellectual Property

The innovation of the AnaeCo™ System has been acknowledged with a portfolio of international patents.

A substantial body of intellectual property (IP) has been created over 15 years in developing the AnaeCo™ System and it has been part of the Company’s long term strategy to protect this IP using patent registration. The development of a technology transfer and licensing business will be underpinned through the strong IP protection currently headlined by fourteen patent families and a portfolio of over 80 international patents and patent applications.

AnaeCo's patent portfolio covers method and apparatus across a range of unique aspects of the AnaeCo™ System and is summarised below.

  • Aerobic-anaerobic-aerobic treatment process

An organic waste material treatment process comprising subjecting the material to conditions under which anaerobic digestion occurs followed by conditions under which aerobic composting occurs, and also pre-conditioned the waste material before anaerobic digestion by subjecting the material to aerobic composting conditions to facilitate a rise in temperature of the organic waste material.

  • Aeration during aerobic treatment

Method and apparatus for aeration of organic material within a sealed vessel, wherein the material undergoes an aerobic composting process such that air is delivered to the contents of the vessel and is caused to evenly penetrate the material such that an air pressure from about 1 to about 1000 kPa above atmospheric pressure is maintained in the vessel.

  • Pulse injection of process fluids

Method and apparatus to introduce fluids by means of a pulse into an organic material that is undergoing a microbiological process such as aerobic composting or anaerobic digestion.

  • Purging exhaust gas

Method of inerting a vessel, using exhaust gas from a power generation plant, in which a microbiological process such as aerobic composting or anaerobic digestion is occurring.

  • DiCOM vessel drainage screens

Screen for the drainage of organic materials where the screen comprises outer and inner screen members in a parallel but laterally off-set arrangement.

  • DiCOM materials recovery facility processing sequence

Method and apparatus for the separation of solid organic waste into fractions based on particle size which includes recirculation of the oversized fraction to improve the efficiency of organic capture.

  • Grit separation system (GSS)

Method and apparatus of separating physical contaminants (e.g. glass and grit) from a solid waste stream by passing the mixed waste through a washing step, with the decontaminated organic fraction being further treated with a drainage step followed by a dewatering step.

  • Pressurised recirculation of OFMSW

Method and apparatus for the pressurised recirculation of organic material within a single vessel where the organic material is transferred between an outlet and an inlet of a vessel while maintaining a pressurised state.

  • Dewatering press back pressure device

Method and apparatus for removing water from solid organic material using a screw conveyer where dewatering is controlled via the adjustment of backpressure, which is based on the rate of change of power demand of a screw conveyer motor.

  • Process control during anaerobic phase

Process control method for the optimisation of the performance of a batch anaerobic digestion process by passing a controlled portion of the process water to a chemostat and monitoring the chemostat effluent to ensure VFA removal.

  • DiCOM vessel hopper geometry, base and reclaim screw system

Method and apparatus for the smooth passage and conveyance of compressible material from a vessel wherein material is conveyed via a series of horizontal parallel screw conveyers, at the outlet of the vessel, feeding material into a second screw conveyer arranged in a transverse arrangement

  • Modular homogenising and screening trommels for mixed municipal solid waste

Apparatus and method for solid waste separation using multiple trommel modules wherein the length of the trommel can be changed to optimise separation for a given waste, each module is able to be run at a different speed, and other physical features are employed to enhance movement and pulverisation of materials through the trommel modules.
