Our #CircularEconomy research has been published in the journal Resources, Conservation & Recycling. In this paper we combine #LCA and industrial ecology methods with system dynamics to measure spatial trade-offs between environmental impacts/benefits linked to increased material circularity. In our case study of Montreal's construction sector between 2017 and 2050, we estimate circularity will reduce environmental burdens in most locations where material production occurs, but these improvements disproportionally benefit wealthier, more developed nations. Meanwhile, impacts due to reuse and remanufacture are expected to increase in the city. Overall, material circularity is environmentally beneficial, but there are risks these benefits will be unevenly and unfairly distributed.

The idea to use the Material Circularity Indicator (MCI) came after talking with former colleague James Goddin - circular economy expert at thinkstep-anz. Thanks Jim! What I find really interesting about the MCI is it's potential to be used in dynamic models as we have done, and be linked to life cycle impact categories. I think an important next step would be to use a consequential LCA approach.
Good piece of work Elliot! Question: how did you allocate the benefit of recycling? Didn't spot the info by scrolling fast: I guess it is a (100,0) or (100,100) allocation?
I was eagerly waiting for this paper to be published ! Looking forward to reading it in full
What a reward to see our article is finally out and in open access in the Journal Resources, Conservation and Recycling ! It was a pleasure to work with you on this topic, eager to read your next research papers 📄🌿
Congratulations, Tom! 🙌
Sounds interesting - added to the reading list!
Bien hâte de lire cette étude.
