The model defines a single circularity index, whose calculation is based on two components:

  • Flow circularity, which takes into account all the components of materials and energy in the phases of:

 >    input (whether renewable, recycled, reused, etc.)

 >    output (recycle, reuse, landfill).

  • Usage circularity, which takes into account the material utilisation factor, either by extending its life cycle or by considering the application of the principles of sharing and "product as a service".

By measuring the circularity index, it will be easier to evaluate the success and effectiveness of the circular economy.
