Lafarge Canada turns Nova Scotia Cement Plant green
Lafarge Canada has been consistently advancing in their journey to Net-Zero. The largest provider of sustainable and innovative building solutions in Canada has announced the full transformation of the Brookfield Cement Plantβs cement production in Nova Scotia to a greener portfolio.
From now on, the siteβs production of general use cement (GU) ends and will shift to reduced carbon portland limestone cement – branded asΒ OneCemΒ – the companyβs eco-efficient alternative. Brookfield is Lafargeβs third cement plant to be converted in 2022 and the first Atlantic Market plant to convert – the others being the Bath Cement Plant (ON) in June and the Richmond Cement Plant (BC) earlier this year, in March.
OneCem is a sustainable product that presents up to 10% lower CO2 emissions while providing the same performance and durability.
βWe have been steadily moving the needle forward when it comes to cement decarbonization and we will continue to honour our commitment in progressing our greener portfolio in Eastern Canada over the coming years. For us at Lafarge Canada, sustainability and profitability go together – our main goal is to keep partnering with our customers to advance sustainable construction and, at the same time, provide innovative world-class products,β commented Andrew Stewart, Vice President, Cement, Lafarge Canada (East).
According to Robert Cumming, Head of Sustainability & Public Affairs, Lafarge Canada (East): βOver the last four years, we avoided more than 140,000 tonnes of CO2 by converting GU cement to OneCem in our plants across Canada – the equivalent to taking 42,891 cars off the road, which would have consumed 59,640,854 liters of gasoline. With the recent cement production conversion of the Brookfield Plant, the Bath Plant in June, and Richmond Plant in March, these numbers will continue to grow.β
βWe are excited to take our plant to the next level of decarbonization. Our teams on the ground have been successfully showcasing our companyβs values of passion, collaboration, and grit, and we couldnβt be prouder. This is a very important milestone in our Net-Zero journey in Nova Scotia and in Canada as a whole,β affirmed Travis Smith, Plant Manager, Brookfield Cement Plant.
The portland limestone cement, OneCem, contributes to lowering the industryβs carbon footprint not only during the manufacturing process – while cement may be as little as 11% of a concrete mix, it can account for more than 80% of all energy required to produce concrete.
Across Canada, Lafarge has produced over 6 million metric tonnes of OneCem since 2011, and users can be confident in its performance while reducing the carbon footprint in the built environment and community.
