Throughout 2025, Refractarios Kelsen has significantly strengthened its commitment to sustainability by enhancing its management systems, validating its environmental and energy performance, and consolidating its position as a company firmly committed to continuous improvement and industrial responsibility.

During the year, Kelsen renewed key certifications that confirm the robustness of its internal processes. ISO 9001 reaffirms the quality and efficiency of its management systems, while ISO 14001 and ISO 45001 underscore the company’s commitment to environmental protection and to the health, safety and wellbeing of its workforce.

At the same time, Kelsen achieved new certifications that reinforce its focus on decarbonisation and energy efficiency. ISO 50001 certifies the optimisation of energy consumption across its facilities, while ISO 14064 and ISO 14067 validate the calculation of carbon footprint at both organisational and product levels, ensuring transparency and accuracy in measuring environmental impact.

This progress has been externally recognised with the award of the EcoVadis Gold Medal, positioning Kelsen among the highest-rated companies worldwide in terms of sustainable performance and responsible business practices.

These achievements align with the roadmap of the Calcinor Group, of which Kelsen is a part, aimed at building a lower-carbon industry through innovation, energy efficiency and the increasing use of recycled raw materials.

“These certifications are not just badges on our website; they ensure that every decision, from product design to final delivery, is guided by sustainability and continuous improvement criteria,” the company states.

Building on this strong foundation, Refractarios Kelsen will continue to promote new initiatives throughout 2026, further advancing towards a more efficient, responsible and future-ready industrial model.
