An article in the May 25 issue, “Serbia Far from EU Rerefining Norms,” initially misidentified the individual who discussed the disposition of used lubricants in Serbia during a presentation at GBC’s CIS Base Oils and Lubricants conference. The presentation was given by NIS Expert Coordinator for Chemicals and Waste Management Srdjan Sokolović. During his talk he cited estimates by Mile Stojiljković, head for quality control and development at NIS’ lubricant division.
