The joint venture, called All4Zero, will manage the development of decarbonisation and circular economy projects in Spain. This is seen as a strategic alliance for the four companies to find common ground in reducing emissions and promoting the reuse of waste and by-products in the steel, energy, aerospace and cement sectors.
The founders said, "At All4Zero, we contribute to the development of technologies that offer promising solutions to the problems of energy transition and climate change. In the evolution towards a circular production economy, the reuse and optimisation of resources are the paths to follow to strengthen the sustainability of the industry. However, this change will require the development of technologies that allow the recovery of waste or the efficiency of processes."
The All4Zero project will be officially presented on 6 September.
ArcelorMittal's plan in Spain involves building a 2.3 million tonnes/year green hydrogen-based direct reduced iron unit complemented by a 1.1 million tonnes/year hybrid EAF to replace the existing blast furnace. The company gave the green light for the EAF investment in early August. The plant is expected to be operational in the second half of 2025.
