SOILCO’s Kembla Grange transfer station was constructed in 2012 and upgraded in 2016 to include an enclosed organics processing building for pre-treatment (sorting, shredding and screening) of 70,000 tonnes per annum of food, garden and timber waste.
In-vessel composting tunnels were also commissioned to hygienise 15,000 tonnes per annum of food and garden waste prior to transfer off site for composting and final production.
In 2020 phase 2 of the upgrade commenced to construct a further four in-vessel composting tunnels at an adjacent site previously used for steel pipe manufacturing. When commissioned in 2021, the combined in-vessel capacity of the facility will be 35,000 tonnes per annum.
Hygienised food and garden waste collected that was previously transported 80km south to Nowra will remain in Kembla Grange.
In-vessel composting technology maximises processing capacity, increasing final output with minimal footprint requirements.
The Kembla Grange upgrade included design and construction of a water treatment plant that will be incorporated into the composting infrastructure. The renovation of the older warehouse also required upgrades to ensure compliance to building code. Consideration of the historical use of this particular part of the facility and protection of its ageing infrastructure for the future operating environment was critical.
The facility also provides SOILCO with capacity to manufacture, warehouse and distribute quality assured compost to Council partners in 20 litre bags for return to the local community.
