Canada: Lafarge has completed a US$20m upgrade at its Exshaw cement plant in Alberta, which will reduce the level of emissions generated by its operations. The upgrade is one part of an ongoing expansion at the plant that will ultimately see Lafarge nearly double the plant's output from 1.2Mt/yr to 2.2Mt/yr.The expansion was originally planned in 2008, but was delayed because of the economic downturn.

Now, with Alberta 'booming again,' the timing is right, according to Bob Cooper, Lafarge vice-president for Western Canada Cement. The project will be completed by the summer of 2015.

"We're quite proud of this because we're helping to build Alberta. "We're the only company in Alberta right now, from a cement standpoint, increasing our output," he said. "The market is quite strong. We see a lot of growth going forward in Alberta, the Prairies and even British Columbia."

The environmental benefits of the expansion and side-projects will be 60% lower sulphur dioxide emissions and 40% lower nitrogen oxide emissions.In addition, new dust mitigation and noise abatement equipment has been installed. Lafarge has also installed a new water recycling system, which means that the plant will no longer discharge used water into the Bow River.
