Eco responsible building projects valuing the principles of sustainable development

As part of its innovation and performance efforts, Cosoltec has given itself the mandate to carry out projects with an emphasis on the 3RV-L principle :

  • Reducing (R1) use of resources;
  • Re-using (R2) recoverable material;
  • Re-cycling (R3) site materials and waste;
  • Value adding (V) materials prioritized on the landfill (L).

By raising awareness among every player involved and by providing resources and skills when applying the highest standards of eco-construction upstream, during and after every project, Cosoltec assists its clients to emerge as examples of sustainable development.
