Revivack is a Barcelona-based startup that makes circularity real, measurable and easy. It offers a digital solution to plan, trace and certify the recovery of products, either individually or within events and physical spaces, via the Revivack Circular Pass, a live digital passport that verifies end-of-life actions and shows real-time impact (CO2 avoided, waste recovered). The company helps brands and organizers turn green goals into certified results.
