CAMP HILL, Pa. – (May 21, 2018) – Harsco Corp. (NYSE: HSC) announced today that its Harsco Metals & Minerals division has successfully renewed and extended two existing contracts – and has been awarded four new Logistics & Packaging contracts – with ArcelorMittal Atlantique & Lorraine (AMAL), one of the largest producers of flat carbon steel in Europe.

The six-year contracts, affecting the six downstream sites, extends Harsco’s Logistics & Packaging strategic position in both ArcelorMittal Atlantique & Lorraine and ArcelorMittal in France.
