The Matériauthèque


CERMIM leveraged its expertise in a three-stage process based on consultation, coaching and knowledge transfer, to equip the Magdalen Islands with a building materials recovery service managed by a local social economy enterprise.

In this sense, the Matériauthèque is an innovative response that improves the environmental balance of the Magdalen Islands while developing a new niche in the circular economy.

The Mandate
in a Nutshell

Here, as in many other places, the challenges of insularity and the urgency of climate change are forcing communities to find original ways of adding value to their resources. This also applies to residual materials.

What Are the Project’s Objectives?

  • Divert the export of residual materials
  • Save money
  • Contribute to efforts to reduce greenhouse gas (GHG) emissions

CERMIM Services
Used in this Project

  • Project management
  • GHG quantification
  • Development of construction methodology
  • Guide production
  • Knowledge transfer
  • Characterization of residual materials

Project Background

Conceived and set up as part of RECYC-QUÉBEC’s Écogestion de chantiers de construction program, the Matériauthèque offers an adapted and sustainable response to one of the region’s major challenges: the management of residual materials from the construction industry.

Now managed and operated by Ré-Utîles, a local company working in the social and circular economy, the Matériauthèque is a winning project that recovers residual materials from the construction industry and shows just how much an island is also a world of innovation.


Benefits for the Environment and the Community

  • 124 tonnes of materials diverted from landfills
  • 195 tonnes of greenhouse gases (CO2 equivalent) avoided by reusing materials
  • $11,000 saved by the Communauté maritime des Îles-de-la-Madeleine for waste management
  • Creating 5 new jobs

And for All Our Partners

  • RECYC-QUÉBEC – Reducing residual materials and GHGs, promoting reuse
  • Ré-Utîles – Capitalizing on infrastructure, developing new expertise, creating jobs and wealth
  • Communauté – Reducing materials sent to landfills, promoting the circular economy, accessing low-cost materials



Demonstrating that reuse helps to reduce GHGs, and that each reused material contributes to this issue

Transfer and sustainability

Providing the partner organization with the tools and knowledge it needs to take charge of the Matériauthèque


Meet the one-year deadline imposed by the RECYC-QUÉBEC project

Benefits for the Environment and the Community

In addition to being 100% ethical and reproducible, the Matériauthèque project successfully integrates all three aspects of sustainable development:

• Social • Economical • Environmental

A Great Example

The Matériauthèque is a fine example of the emergence of a new form of economy where the negative value of materials considered and treated as waste is transformed into an income of over $1,000/tonne.
