The Material Circularity Indicator (MCI) tool enables companies to identify circular value from their products and materials. MCI allows companies to evaluate the environmental, regulatory, and supply chain risks for products. Companies can use MCI to input data on a product and measure the circularity of material flows for that product and group it with other products to understand company impact. The tool supports decision making between circularity and the economic, environmental, and societal objectives on product design and materials procurement.
