The electric arc calcination (EAC) technology from Sweden’s Salt X company may change the industrial calcination in the global cement and lime industry. The plasma technology can not eliminate the CO2 formation from calcining limestone, but enables cost efficient carbon capture because of a closed process. Salt X is working on ZEQL (Zero Emission Quicklime) – the world’s first fully green electrified quicklime plant (illustration), which shall be ready by 2025. ABB partners with Salt X as a minority shareholder and supplier of automation and electrical systems.
