SynopsisArcelorMittal has joined forces with Repsol, Iberia, and Holcim Group to establish the All4Zero initiative, an industrial technology and innovation hub in Spain. This collaboration aims to drive decarbonization and circular economy projects, fostering sustainability in the steel, energy, aviation, and cement sectors. ArcelorMittal's contribution includes the construction of a green hydrogen-based direct reduced iron unit and a hybrid EAF, marking a significant step towards reducing emissions.ArticleIn a significant move towards advancing sustainability and decarbonization efforts, ArcelorMittal has forged a strategic partnership with energy company Repsol, carrier Iberia, and cement giant Holcim Group. Together, they are set to create a transformative industrial technology and innovation hub known as All4Zero in Spain.The primary goal of the All4Zero joint venture is to spearhead the development of decarbonization and circular economy projects in Spain. This collaborative initiative brings together the expertise and resources of four major players in the steel, energy, aviation, and cement industries, all united by a shared commitment to reducing emissions and promoting the efficient reuse of waste and by-products."At All4Zero, we are dedicated to fostering the development of technologies that hold promising solutions for addressing the challenges of the energy transition and climate change," state the founders of this visionary project. "As we transition towards a circular production economy, the optimization of resources and waste recovery are pivotal for reinforcing industry sustainability. However, this transition necessitates the advancement of technologies that enable efficient waste recovery and process optimization."The official presentation of the All4Zero project is scheduled for September 6th, marking a significant milestone in the pursuit of environmentally responsible industrial practices.ArcelorMittal's contribution to this innovative endeavor in Spain is poised to make a substantial impact. Their plans include the construction of a 2.3 million tonnes/year green hydrogen-based direct reduced iron unit. This will be complemented by a 1.1 million metric tons per year hybrid Electric Arc Furnace, which will replace the current blast furnace. The approval for the EAF investment was granted by ArcelorMittal in early August, and the facility is expected to become operational in the second half of 2025.Conclusion ArcelorMittal's involvement in the All4Zero initiative underscores their dedication to pioneering sustainable technologies and practices, marking a significant step towards a greener and more environmentally conscious industrial landscape.
