The 2022 Synergy Compendium demonstrates the intensification of circular economy approaches in Quebec

Cover Synergy Collection 2022
For the third consecutive year, the Synergie Québec community of practice has published its Compendium of Synergies, which highlights the growing variety and richness of resource networking.

Each of the thirteen concrete examples of synergies is presented by the industrial symbiosis that initiated and accompanied it. These documented success stories show a great diversity in the materials, the exchange and sharing modalities, and in the sectors and types of companies involved in the shift towards the circular economy.

" When the wind of change blows, some build walls, others build windmills. We chose this proverb to illustrate synergies in order to pay tribute to the work of the facilitators of symbioses and to the entrepreneurs who are open to circular innovation," explains Claude Maheux-Picard, executive director of the Centre de transfert technologique en écologie industrielle (CTTÉI). "This year's collection shows that the two main success factors in the transition to the circular economy are: the innovative spirit of the entrepreneurs, and the support of the symbiosis facilitators in the field.  

This edition required the collaboration of nearly 20 volunteer facilitators from 13 Quebec industrial symbioses, in addition to the CTTÉI's expertise in calculating spinoffs. Thus, convincing benefits are put forward: volume of materials diverted from landfill, reduction of greenhouse gas emissions, financial savings, job creation, skills transfer, etc.

The publication of the compendium is highly anticipated in the sustainability ecosystem and in the educational community. It can be downloaded free of charge from and The 2021 edition of the Synergy Compendium has been downloaded over 2800 times since May 2021.
