Wogamia Infrastructure Project Update

Final works on a $1.2 million infrastructure project at Soilco’s Nowra facility are now nearing completion.

Final works on a $1.2 million infrastructure project at SOILCO’s Nowra facility are now nearing completion.



The project is supported by the Environmental Trust as part of the NSW EPA’s Waste Less, Recycle More initiative, funded from the waste levy.


The upgrade has been designed by Dutch company Waste Treatment Technologies (WTT). A 3,600m2 concrete pavement will be arranged with twelve sets of aeration pipes connected to two fresh air supply fans. Each aeration bay has its own dedicated air supply and wireless probes are placed in the composting material to provide real time monitoring of temperature.


The automated process can be visually managed from a process computer and specific batch reports produced to ensure compliance with relevant quality and environmental standards.  When completed the aeration system will provide an increased process efficiency and enable SOILCO to reduce its current composting footprint from approximately 15,000m2 to 5,000m2!


The Wogamia project will be WTT’s second with SOILCO following installation of air, water and process controls at the company’s organics recycling facility in Kembla Grange during January 2017. In May 2018 SOILCO received development approval from Wollongong City Council to construct a second composting and manufacturing facility in Kembla Grange. On completion, the Kembla Grange facility will distribute 50,000 tonnes per annum of soil, compost & mulch products derived from urban and forestry waste materials.
