Call for Interest

to identify polluted soil owners interested in innovative and cost-effective solutions for brownfields decontamination



The Call for Interest is addressed at public procurers, soil owners and management authorities involved in the procurement chain interested in new solutions for brownfield decontamination in an innovative and cost-effective way. The overall aim of the call is to create a dynamic and interested critical mass of investments so to accelerate innovation in the decontamination sector.


“POSIDON PCP – POlluted SIte DecontaminatiON” has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement N. 776838.

The POSIDON challenge is to address the lack of innovation in the soil decontamination sector in Europe and investing in research and development services. Pre- commercial procurement (PCP) is the most effective demand side innovation instrument par excellence. PCP is articulated in 3 phases, namely: concept design and feasibility study, prototyping and lab demonstration, field testing.

By facilitating transnational R&D and enabling the comparative analysis of alternative novel and promising prototypes, POSIDON offers an opportunity to interested procurers across EU to re-think and re-design their concrete investments and proceedings for the local brownfields’ decontamination and remediation plans for the coming years, leveraging their complementarities and expertise.

The decontamination demand is very fragmented, and the value of the procurement is often too modest for the technology providers to ensure an adequate return of the investment, preventing existing resourced to flow to new technological frontiers

For this reason, POSIDON project managed to mobilize public and private purchasers and networks of cities in the field of soil decontamination, which shared the same needs as described in POSIDON Technical Prospectus and selected 6 solutions in phase 1, 4 solutions in phase 2 and 2 solutions in phase 3.

The POSIDON prototypes developed during Phase 2 are:

  • “ReMix” technology: two-phase, soil washing plus biological treatment, innovative remediation method, which does not require existing infrastructure and can be implemented directly on brownfield sites, designed to remove Lead, Arsenic (and other toxic metals), and recalcitrant organic pollutants, capable of treating the soils - from sandy to more clayey - preserving the natural living substrate, the functions of the soil and the ecosystem. Developed by Consortium formed by ENVIT Ltd, ARHEL Ltd
  • "RIBAS -Reactive Infiltration BAsin for in-situ Soil treatment" technology:  Intermittent soil washing with saturated or partially saturated infiltration of an innovative reactive solution that degrades organic compounds and mobilizes metals to be captured downstream by precipitation. Developed by Consortium formed by Fundació Eurecat, Amphos 21 Consulting SL
  • “ERASE - ElectRode-Aided Soil rEmediation” technology: flexible in situ modular platform with installation of electrodes for addressing various organic and inorganic pollutants and co-contamination, through the transport induced by the electric field in the soil while stimulating chemical and biological treatment actions by injection of chemicals and nutrients. Developed by Consortium formed by HPC ITALIA S.r.l., Fondazione Politecnico di Milano, Ambiente S.p.A., HPC International SAS, GEYSER HPC S.A.U. (see “ERASE” video)
  • “Soil-Omic” process: innovative protocol that uses combined biological and chemical-physical processes, based on the integration of metagenomics and environmental engineering, and aimed at the decontamination of soils and groundwater from organic and inorganic pollutants. The “Soil-Omic” procedure is applied in situ through the operating technology of "Bioflushing", an original technological system that purifies contaminated groundwater and establishes a circulation of specific biological and chemical-physical solutions in the subsoil aimed to the degradation of organic contaminants and removal of inorganic contaminants. Developed by Consortium formed by TB TESECO BONIFICHE, IRET-CNR, Agencia Estatal Consejo superior de lnvestigaciones Cientificas CSIC, DN 360 srl, BioCastle Water Technologies LDT, Studio Podgornik srl, BD BIODIGRESSIONI srl (see “Soil-Omic” video)

The Call for interest is addressed to public and private soil owners and procuring entities responsible for decontamination initiatives in EU Member States that are interested to start or plan a coordinated public procurement of innovative solutions (PPI) in a next future.

Type of information to be provided

The call for interest requires to owners of soils affected by serious case of contamination to provide relevant information about the site, based on technical assessment already carried out, in order to assess common characteristics with the two pilots (Trieste, Bilbao), currently engaged in the testing phase.


Applicants will be asked to:

  • Appoint a primary contact person and provide personal information to be able to contact you, if required
  • Provide info about pertinent soils and contamination characterization
  • Express interest to receive information about testing activities and POSIDON results and/or participate in the preparation of follow-up procurement actions
  • Allow POSIDON project to report to stakeholders, the manifested interest to join POSIDON network and/or collaboration in the project.
