Hi Joan,

Interesting question!

We ran a project on this subject within the Resource Recovery from Waste programme, called "Complex Value Optimisation for Resource Recovery". This included the development of a new approach for the assessment of circular supply chains. More details and publications can be found here https://rrfw.org.uk/projects/c-vorr/

We also started to integrate the tool into a new approach for circular business model innovation. It's a work in progress and you can find our initial ideas in this report Technical Report Set up of the Cooperative Processing Business Model: Proceed...

Kind regards,

Anne
