ABSTRACT
Building the underground infrastructures of the Future Circular Collider (FCC) in the Geneva Basin will produce approximately 6.3 million cubic meters of excavated materials, mainly molasse (95%). The study for this particle-collider based research infrastructure is co-funded by the European Union (EU) in the frame of the H2020 programme. In accordance with the principles of the circular economy, the study aims at developing approaches for the reuse and recovery of excavated materials. The subsurface infrastructure spans over the border between France and Switzerland, hence, logistics, planning, impacts of construction methods, are additional topics addressed by the EU co-funded project deliverable: “Excavated materials management and use strategy”. This paper describes the main principles of the proposed strategy. Although this strategy was defined for a specific settlement and in compliance with French and Swiss regulations, the main principles can be applied to other projects. Anticipation and territorial analysis are both key points for the successful management of excavated materials to ensure the technical and economic feasibility of the project and to strengthen its societal acceptability. In the study case of the FCC, should the decision to build the FCC be taken, the strategy will be completed with relevant operational documents.
