The valorization of marine residues from the activities of the archipelago's processing plants is at the heart of the Green Concrete project conducted by the Centre de recherche sur les milieux insulaires et maritimes (CERMIM) team. The Centre de transfert technologique en écologie industrielle (CTTÉI) has supported the CERMIM's research in order to identify recovery solutions.
- Marine fishing residues and dredging sediments valorized to manufacture wave-breaking concrete blocks in the Magdalen Islands, in collaboration with the Centre de recherche sur les milieux insulaires et maritimes (CERMIM)
- At the CTTÉI, clam shells, lobster and crab shells were crushed and ground. The resulting alternative sands and supplementary cementing materials were tested for use in concrete.
Opportunities and benefits
- Pilot production plant in the Magdalen Islands as part of the Green Concrete program.
- The use of residual materials saves virgin raw materials.
- The supply is local, and more economical than importing.
