Canada: Lafarge Canada has announced the completion of modernisation and environmental upgrades at its Exshaw cement plant in Alberta. The plant has increased its cement production capacity to 2.2Mt/yr from 1.3Mt/yr. Environmental improvements have led to a 60% reduction in sulphur dioxide emissions, a 40% reduction in nitrogen oxide emissions and a reduction in fugitive dust and noise coming from the plant's equipment. The plant has also achieved zero water discharge from its operations.
"It is an incredible achievement to comple a project of this scale. Completing it safely takes focus and energy and I applaud the team for its dedication to this goal," said René Thibault, President and CEO, Lafarge, Western Canada. "By all accounts we consider the project to be a success, cementing our long term commitment to Exshaw, Alberta and western Canada."
The upgrade consisted of shutting down the plant’s kiln four in November 2015. It modernised kiln five to meet new emissions targets by retiring less efficient gravel-bed filter technology. It then built a new production line, kiln six, with a baghouse to collect particulates, as well as a vertical raw mill, a EcoDome storage facility, a pre-heater tower and a vertical cement mill.
Construction at the plant began in 2013, with more than 600 contracted employees on site at the peak of construction activity in addition to 160 permanent employees. The team achieved nearly three million hours without a lost time incident.
