POSIDON gathers European procurers facing similar problems in the contaminated sites they manage, affected by analogous pollutants, leveraging public demand to identify fit-for-purpose and cost-effective innovative and sustainable solutions to soil contamination.

The common challenge faced by the POSIDON buyers’ group is identifying a soil (and eventually groundwater) remediation new, life-cycle, cost-effective technology, preferred as in-situ (and eventually on-site), to be capable of decontaminate heterogeneous anthropic soils in brownfield, composed by a mixture of industrial waste (like filling soils highly polluted by Petroleum Hydrocarbons) and soils consisting on clays and sands, highly polluted by Petroleum hydrocarbons (TPHs and PAHs), and heavy metals.

The selected technologies as remedial solutions, will be applicable on each specific brownfield (Trieste, Bilbao, Lisbon/Seixal, Vitoria- Gasteiz and Liege), for a similar performance range. High cost effectiveness, short time performance and green sustainable guidelines will be crucial for the technology selection. The application of such innovative solutions is expected to contribute significantly to leverage this case study on brownfields redevelopment, and, in addition, to be successfully applicable in similar brownfields across EU.
