The diversion challenge is greater in the commercial sector which has similar large quantities but which are heterogenous and generated from thousands of sources. In addition, and far more than the municipal sector, the C&I sector is driven by economics.
In Australia, a destination-based approach to the C&I sector using separation technology is the most likely viable means of recovering significant proportions of this stream. Without government intervention, this will only happen where landfill costs are high enough to make investment in technology worthwhile.
Currently only Sydney approaches this situation (landfill costs have now exceeded $176/tonne) and it is most likely that there will be a significant a number of C&I waste processing facilities coming on line in Sydney over the next 5-10 years. Most of these facilities will use or adapt proven technology from overseas to sort dry materials, with wet materials such as food collected separately and processed in biological treatment plants. Like current municipal AWT facilities, these new plants would use a combination of technologies to handle and process more materials to the greatest extent possible. It is also likely that different technologies would be implemented at different facilities.
