US: The Holcim US Ada plant in Oklahoma, a member of LafargeHolcim, has seen the completion of its three-year, US$100m new kiln and modernisation project. The project has boosted the plant’s capacity by 20%, raising its clinker capacity to 0.68Mt/yr from 0.62Mt/yr. The upgrades allow the plant to conform to the US National Emissions Standards for Hazardous Air Pollutants (NESHAP) regulations.
Mike Langan, Ada plant manager, said, "NESHAP is one performance standard that's fairly restrictive. New Source Performance Standards are the most restrictive environmental regulations in our industry and this plant meets that. So it is much cleaner environmentally (than before)."
The upgrades made it possible for the plant to increase its use of fuel derived from scrap tires, replacing at least 20% of the fossil fuel used in the new kiln line. That change will make the operation cleaner and more efficient, supporting LafargeHolcim's sustainable-development goals.
