SOILCO has been processing garden and timber waste at the Wogamia site in Nowra since 2001. Further infrastructure improvements were completed in 2018.
Our infrastructure improvements at Wogamia included conversion of existing turned piled (windrow) composting infrastructure to a 30,000 tonnes per annum forced aeration static pile composting system for food and garden organics.
This reduced the facility’s composting footprint from 20,000 to 5,000 square metres. It also improved environmental and process controls as well as efficiency in our operations, including:
- Greater throughput capacity on a smaller budget and footprint.
- Additional process controls to manage air, water and electricity.
- Improved monitoring of materials to ensure end product compliance.
- Optimised sustainability to reduce energy use and carbon footprint.
- Increased water storage so rainwater can be harvested on site.
- Lower operating costs and ongoing machinery costs.
- More environmental controls to ensure sustainable operations.
The project was supported by the Environmental Trust as part of the NSW EPA’s Waste Less, Recycle More initiative, funded from the waste levy.
The aerated static pile composting system is suited to facilities with larger composting footprint and lower infrastructure requirements.
