ThyssenKrupp Nirosta is now using an enhanced technology to recycle the spent mixed acid from the annealing and pickling lines at the Krefeld cold rolling mill. The new regeneration system allows valuable substances to be recovered and fed back to the processing lines. "This innovative process delivers numerous benefits to the environment and our production operations and is also more cost-efficient," says Michael Fitzek, environmental officer at ThyssenKrupp Nirosta. The acid recovery system started operation in April and will reach full optimization in the summer.
