The result of the model is a circularity index, which is calculated based on a combination of two components:
- Circularity of flow, considers the origin and intended use of materials and energy in the phases of:
> Input (percentage of matter and energy of renewable or non-renewable, recycled, reused origin, etc.).
> Output (percentage of matter and energy that will be upcycled, recycled, reused or non-recovered waste).
- Circularity of use, considers the increase in the asset's use factor and useful life, either by extending its life cycle or applying the “shared use platforms” and “product as service” pillars.
When measuring the circularity index, it will be easier to evaluate the success and effectiveness of the circular economy.
