The objective of the Circularity Indicators Project is to provide indicators to estimate the circularity of products and businesses.
The Material Circularity Indicator (MCI) gives a value between 0 and 1 where higher values indicate a higher circularity. The following inputs are used to calculate the MCI:
- Input in the production process: How much input is coming from virgin and recycled materials and reused components?
- Utility during use phase: How long and intensely is the product used compared to an industry average product of similar type? This takes into account increased durability of products, but also repair/ maintenance and shared consumption business models.
- Destination after use: How much material goes into landfill (or energy recovery), how much is collected for recycling, which components are collected for reuse?
- Efficiency of recycling: How efficient are the recycling processes used to produce recycled input and to recycle material after use?
Together with the methodology, the project developed a commercially-available web-based tool for businesses to track their progress in ensuring that their products fit a circular economy based business model.
Were users can either import, build and edit bills of materials for products or designs through a web app or they can work within a CAD system. In either case, users can run reports that analyse bills of materials in order to assess product risk and guide design decisions:
The developed Circularity Indicators are particularly intended for use in product design, but could also be used in internal reporting or for procurement and investment decisions.
