Harsco Signs $50 Million Contract for EPA-Led Cleanup of Alabama Steel Site

HARRISBURG, Pa., Nov. 3, 2009 (GLOBE NEWSWIRE) -- Worldwide industrial services
company Harsco Corporation (NYSE:HSC) announced today the signing of a new
multi-year environmental services contract valued at more than $50 million to
handle the metal recovery and on-site removal of decades-old slag stockpiles
left behind by a former steel manufacturing plant in Gadsden, Alabama.

Under the contract signed with overall site manager, CMC, Inc., Harsco will
install and operate an on-site metal recovery and slag processing operation that
will process an estimated three million cubic yards of slag materials still
remaining from the former Gulf States Steel facility which filed for bankruptcy
in 1999. Harsco will recover the slag's valuable metallic content and process
the remaining material so that it can be responsibly recycled or placed in a
landfill. Harsco's operations, scheduled to begin in January 2010, are expected
to create approximately 20 new jobs, all of which the Company plans to fill with
local hires. The EPA has said it expects the project to be fully funded by the
commercialization of the recovered metals, and considers it a potential model
for future cleanup of similar sites throughout the United States.

Harsco Corporation is a diversified industrial services company serving global
industries that are fundamental to worldwide economic growth, including
infrastructure, metals, railways, and energy. Harsco is recognized as one of the
Fortune 1000 leading companies in America and has been named five times to the
Platinum 400 list of the best big companies by Forbes magazine. Harsco's common
stock is a component of the S&P Mid Cap 400 and the Russell 1000 index.
