Funded project – Contaminated soil washing technology
Establishing a soil washing plant to transform contaminated soils into re-usable aggregate, sand and road base.
Background
EarthSure (a joint venture between Ventia and Veolia) will relocate a soil washing plant as a supplementary treatment option on their existing waste management site in Dandenong South. The soil washing plant will transform contaminated soils into beneficial reuse products.
The existing EarthSure facility onsite remediates Category A (most hazardous type of waste) and B contaminated soils using state-of-the-art thermal desorption technology. The addition of the soil washing facility provides another cost effective and sustainable reuse options, particularly for Category C soils, diverting these from landfill.
The output of the soil washing plant is a range of sands and aggregates that can be returned to the site of origin or reused for civil and construction projects. The small amount of waste concentrate from soil washing is treated onsite by thermal desorption, meaning no transport of residues is required.
Objectives
- Increase the recovery and local reprocessing of hazardous waste
- Relocate up to 30 tonne per hour soil washing plant
- Divert more than 160,000 tonnes of Category C soils from landfill per annum
- Provide 98% of washed soils for beneficially reused as construction materials
- Generate a new circular economy business model and jobs in regional Victoria.
