Hi @nstosurbassett Nice to meet you! Erica here from London.
Interesting question and also good for us to be aware, think about the different terms, perspectives from around the world. I’ll check through the ogranising materials for simplified descriptions (also something we can look at in our communications). Here I would say Circular Economy is still a fairly niche phrase beginning to be adopted by larger corporates. This report from Fusion last year surveyed SME’s and used the description - “If the circular economy is defined as a model whereby products are repaired, reused or upgraded instead of being thrown away and recovered waste materials are reprocessed for remanufacture"
It will be great to build up resources, links that can help with this as well.
One nice example is a project I worked with here called The Rubbish Diet - we held a session on making the Circular Economy more real to people. A nice way to put it was would how would you describe it to Mark’s Grandma (Nan), who would say isn’t that just common sense 
. Anyway here’s a summary of some of the feedback from that.
