ABB helps revolutionize waste management


Source: ABB

Designed and engineered by Australian company AnaeCo, the first installation of this patented technology known as DiCOM® is currently under construction at a municipal waste transfer station* in Perth, Australia’s fourth largest city.

DiCOM is an automated bioconversion process that converts municipal waste into high quality compost which would otherwise be incinerated or transported to a landfill. The biogas produced during the process is used to generate renewable emissions-free electricity to power the facility. Surplus electricity - enough to meet the annual needs of several thousand Australian homes – is sold to the grid.

In developing this first installation AnaeCo required a partner who could provide a complete and integrated solution that would both power and automate the entire bioconversion process.

ABB’s extensive scope of supply includes a process control system based on ABB’s award-winning Extended Automation System 800xA, field instrumentation and gas analyzers for safe and hazardous areas integrated with System 800xA through Profibus, variable speed drives also integrated with System 800xA through Profibus, and electrical equipment to power the process and export the surplus energy to the local power grid.

Integrated waste recovery

The DiCOM system offers the waste treatment industry considerable benefits. The system is compact, modular, sealed and does not emit odor – a key factor in sensitive urban environments where waste transfer stations are often located. Non-organic material is rapidly sorted from each batch prior to the conversion of the remaining organic waste into compost and biogas.

For the end customer, Western Metropolitan Regional Council, DiCOM is transforming a simple waste transfer station into an integrated waste recovery and bioconversion facility. Waste that was previously transported 40 kilometers through residential areas to a landfill in a three-hour return journey is now processed cleanly and profitably onsite.

DiCOM is attracting widespread interest from municipal waste facilities all over the world, with several additional orders from Australia and Europe already in the pipeline.

* A waste transfer station is a facility where municipal solid waste is unloaded from collection vehicles and briefly held before it is reloaded onto larger long-distance vehicles for transport to landfills or other treatment or disposal facilities.
