Lafarge converts Canadian Cement Plant to less Carbon-intensive OneCem

Cement firm Lafarge has converted its Bath Cement Plant near Kingston, Ontario to reduced carbon Portland limestone cement, which is branded as OneCem, from general use cement (GU).

The conversion to OneCem means lower CO2 emissions and provides the same performance and durability. Cement typically represents only 11% of the concrete mix but accounts for over 80% of the energy required for producing concrete.

“At the Bath Plant, we are excited to increase our OneCem production and to provide our customers with this sustainable product, so that every project they build with our product can have a smaller carbon footprint,” affirms Ignacio Arroyo, Bath Cement Plant Manager.

The OneCem is comprised of a higher percentage of limestone. Lafarge owners Holcim previously has transitioned several cement plants in the U.S. to the new product.

Across Canada, Lafarge has produced over 6 million metric tons of OneCem since 2011
