SMA Mineral and SaltX launch ZEQL – an electrified factory concept for climate-neutral lime production

Since spring 2022, the two companies have been working together to create an electrified concept for industrial-scale climate-neutral lime production. Last summer, SMA Mineral became a shareholder in SaltX Technology by acquiring 15% of the company. Now, the parties are launching a joint factory concept and brand, ZEQL (Zero Emission Quicklime), to raise awareness of the concept and highlight the importance of limestone in modern society. The first factory is expected to be completed by 2025.

The co-owned concept is based on SaltX's patented technology for electric calcination, Electric Arc Calciner (EAC). The technology replaces oil and coal with fossil-free electricity and captures the carbon dioxide released during the intense heating of limestone. SMA Mineral plans to replace its existing plants with the new ZEQL concept. Svante Fielding, CEO of SMA Mineral, says: 

"The market has responded in the best possible way, and we look forward to soon starting the construction of the first plant. We have an aggressive plan ahead, making ZEQL one of the most comprehensive electrification initiatives happening in the industry right now." 

 The two companies are creating a new joint brand and factory concept to increase awareness and interest in the electrified manufacturing method and, in the future, offer other actors to utilize the concept to minimize their climate impact. Carl-Johan Linér, CEO of SaltX, says: 

"The investment in a joint brand and factory concept strengthens our position as a leading player and driver of the industry's transformation. Our common ambition is for the ZEQL concept to become the new standard for climate-neutral lime production for the entire industry."
