Lanxess switches Krefeld-Uerdingen iron oxide pigment dryer to hydrogen, cutting CO2 by 6,000 tons a year
XLB•Emissions cut and hydrogen supply
The change will cut the unit's annual CO2 footprint by about 6,000 metric tons.
Hydrogen is supplied via pipeline from adjacent Covestro operations, sourced as a byproduct from chlorine electrolysis.
The hydrogen burner was installed in late 2025, with phased commissioning supported by upgraded controls, metering and safety systems.
