Alternative Waste plant, to be controlled by ABB

ABB’s automation solution System 800xA will control an Alternative Waste Technology (AWT) facility to be based in Shenton Park, Western Australia.

ABB will supply the complete hardware, engineering and commissioning of the control system, drives, analysers, instruments and field devices.

The facility is based on the DiCOM bioconversion process and will be situated immediately adjacent to an existing transfer station building and will for the first time in Australia, allow for the retrofitting of existing Transfer Stations with municipal solid waste processing technology. The plant will include a waste sorting and preparation facility and three DiCOM biological processing vessels, including associated ancillary equipment.

Hafeez Abdulaziz, Projects Proposal Engineer, ABB Australia, says: “ABB is thrilled to be involved with this project as it will be a powerful demonstration of the potential that this technology presents in the municipal solid waste (MSW) processing sector. The DiCOM process is a community friendly and environmentally sustainable alternative to landfill disposal of putrescible wastes.“

Hafeez adds: “The process will be fully automated using ABB System 800xA with extensive use of Profibus communication protocol for all the drives and field devices. The plant process data will be monitored and controlled remotely from the AnaeCo staging facility. Sensors will monitor the conditions within each vessel and will set and vary the flow of air and water, thereby regulating moisture levels, temperature, pressure, oxygen, carbon dioxide and methane, as well as odour generation and control.”

The controls concept was developed by Hero Engineering, and they will be working closely with ABB. The project will be delivered in two stages, with the second stage commencing approximately six months after the completion of stage one.
