Center for the Transfer of Technologies in industrial ecology

Cégep Sorel-Tracy


Affiliated with the Cégep de Sorel-Tracy, the mission of the Centre de transfert technologique en écologie industrielle is to increase the performance of businesses and communities through research and development of innovative approaches and technologies in industrial ecology.

CTTÉI is a leader in the transition to the circular economy through its pragmatic, innovative and bold industrial ecology solutions in three sectors: the development of industrial residues through the search for innovative opportunities in profitability, the implementation of clean processes and the deployment of industrial symbioses. The centre has a laboratory for formulation of concretes, mortars and geopolymers and a laboratory specialized in supercritical fluids. A semi-industrial hydrothermal oxidation platform is under construction.

In keeping with the Politique de gestion des matières résiduelles québécoises, CTTÉI’s approach is to favor the 3 RVs (Reduce, Reuse, Recycle and Valuate) and demonstrate that waste can become a resource and constitute added value for the company:


  • Characterization of materials and market research for aging metro wagons
  • CO2 sequestration by metallurgical by-products
  • Concrete development with high recycled content
  • Development of materials for the manufacture of degradable funeral urns
  • Establishment of an industrial symbiosis in Brome-Missisquoi, Lanaudière and Bécancour
  • Hydrothermal oxidation of industrial organic effluents
  • Supercritical CO2 bitumen extraction of used asphalt shingles
  • Etc.
