flag Spain and SMX pilot blockchain tracking in Valladolid to make sustainability measurable and tradable.

flag Spain and New York-based SMX have launched a pilot partnership in Valladolid to turn sustainability into a measurable, tradable asset using molecular "physical-to-digital" tracking. flag The technology embeds invisible, unforgeable markers into materials like plastics and metals, creating immutable blockchain records of their lifecycle. flag Researchers at CARTIF are evaluating the system’s ability to verify recycled content, support ESG compliance, and unlock sustainability-linked financing. flag The initiative, part of Spain’s Castilla y León region’s industrial strategy, aims to transform circularity from a promise into a performance metric with economic value. flag If successful, the system could enable full supply chain traceability across Europe, positioning Spain as a leader in the circular economy. flag Final agreements are pending.
