With this project, we adopted what’s known as a Return on Sustainability Investment (ROSI) method and applied it to the case of used, end-of-life tires. We used this approach to guide business decision making from a financial perspective, focusing on recovering textile fibers in tires and then using them for the construction of other materials.

Several benefits arose in this process, including avoiding waste disposal costs, new revenue from the sale of recovered materials, and an overall reduction in carbon emissions. This study used available data from the European market, but the framework forms a strong basis for other relevant cases in North America.
