US steelmaker Pacific Steel Group has selected Italian manufacturer Danieli to supply its advanced ECO Primary line, an environmental control system developed by Danieli, for its MiDa hybrid plant in California. This project represents an important milestone in sustainable valve production with advanced emissions controls and readiness for carbon capture integration.
Advanced emissions controls for California green steel plant
The Danieli ECO core line will be used in the upcoming PSG Hybrid MiDa plant in California, designed to install new standards in environmental indicators. Through extensive research and development, Danieli has developed a complete solution to minimize electric arc furnace (EAF) emissions to industry-leading low levels.
The system is specifically designed for:
- nitrogen oxides (NOx)
- sulfur oxides (SOx)
- filterable and condensable particulate matter (PM)
- volatile organic compounds (VOCs)
This technology will significantly reduce air pollution while meeting California's stringent environmental regulations.
The main ECO line will be built with a carbon capture system in mind, allowing for future integration of carbon capture technologies.
