Water

  • In water the investments reached € 0’55 million (since 2008), including:
  • Reconstruction of process tank nº4 at Pickling line: reduction in water consumption, preventing leakages
  • New inside coating in electrolyte tank at Electro galvanising line: reduction in water and electrolyte consumption, preventing leakages
  • Apart from this, in 2011 ArcelorMittal Sagunto has made a characterization study of sewage at all its lines, for the introduction of improvements.
  • ArcelorMittal Sagunto has reached a Reduction in discharge ratio: from 0’656 m3/t HRCe (2008) to 0’516 m3/t HRCe* (2011)
  • ArcelorMittal Sagunto has reached a Reduction in water consumption: from 1’185 m3/t HRCe (2008) to 1’014 m3/t HRCe* (2011)

Residues

  • In residues the investments reached € 4’4 million (since 2008), including:
  • Replacing 2 grinding machines at Roll shop: reduction of grinding dust residues, requalification from hazardous residue to non hazardous residue (as a consequence of technology change).
  • Replacing edge cutter at Pickling line: reduction in scraps
  • New auto inspection system at Hot dip galvanizing line: reduction in scraps
  • ArcelorMittal Sagunto has reached a Reduction in hazardous residues ratio: from 0’96 kg/t HRCe (2008) to 0’87 kg/t HRCe (2011)
  • Since year 2000, Sagunto site has an Acid Regeneration Plant, which it is considered as a BAT, where all the wasted HCl acid is regenerated and reused at the Pickling line.
