IMMEDIATE RELEASE
Harsco And Lanzatech Sign Strategic Alliance to Advance the Production of Clean Energy From Steel Mill Gases
HARRISBURG, PA (August 15, 2011) . . . Worldwide industrial solutions company Harsco Corporation (NYSE: HSC) and clean
energy technology company LanzaTech today jointly announced the signing of a strategic alliance to promote the capture
and reuse of steel mill flue gases as an environmentally significant and beneficial source of reliable energy.
The agreement, signed today at Harsco’s world headquarters, taps into Harsco’s global leadership serving the worldwide
steel industry, in combination with LanzaTech’s proprietary bioenergy technologies for reducing the carbon footprint of
integrated steelmaking operations. Together, the two companies will jointly develop plans to present the LanzaTech
biotechnology to Harsco’s major steel mill customers and explore potential business relationships for installing and
operating commercial facilities at selected sites throughout the world.
Founded in 2005, LanzaTech is the first company to successfully demonstrate production of fuel-grade ethanol from steel
mill gases. Its proprietary biotechnologies convert the waste gases emitted by blast furnace, coke oven and BOF
operations into low cost, zero carbon ethanol, thereby significantly reducing greenhouse gas emissions while also
providing a commercially scalable alternative to traditional ethanol production and its heavy reliance on agricultural
food crops. The agreement with Harsco will now accelerate the introduction of this technology to steelmaking customers
throughout the Americas, Europe and selected emerging markets.
“The conversion of industrial waste streams into beneficial ‘green’ resources has long been a Harsco mainstay,” said
Harsco Chairman, President and CEO Salvatore Fazzolari. “With LanzaTech, we now add another dimension to our ability to
bring innovation to our customers and at the same time, help build a more sustainable environment.”
Added LanzaTech CEO Dr. Jennifer Holmgren, “Harsco’s commitment to minimizing the environmental impact of metal
production processes is in line with the unique technology LanzaTech has developed. As heavy industries worldwide face
an increasingly stringent regulatory climate, our relationships with committed partners such as Harsco respond to these
challenges with technology-based solutions for a cleaner environment that also enable continued growth.”
About LanzaTech
Founded in New Zealand in 2005, LanzaTech has developed a novel gas-liquid fermentation process that produces fuel grade
ethanol and key chemical building blocks used to make polymers, plastics and hydrocarbon fuels. With agreements now in
