David Stringer, who is leading a battle against a major cement operation that wants to set up shop in his eastern Ontario community, sees the irony in his role. Stringer, 81, a structural engineer by profession, is president of the Vankleek Hill and District Nature Society, a citizens group that has joined forces with three environmental organizations in a bitter fight to prevent a major Canadian cement company from opening a plant on 56 hectares near L’Orignal, a quiet Ontario village nestled between Ottawa and Montreal.Colacem Canada, owned by Quebec-based Beton Provincial Inc., says the plant would produce 3,000 tonnes of clinker — the main ingredient in cement and the most greenhouse gas intensive component of cement manufacturing — each day. The company estimates it would produce 1.16 million tonnes of cement per year, operating around the clock seven days a week.Stringer’s group and the others are trying to block this from happening. Of major concern, says Stringer, is global warning.“These cement plants pump a huge amount of CO2 into the atmosphere,” he says.For Stringer, the irony lies in the fact that he works as an engineer for New York City construction projects — which depend heavily on cement and its end product concrete.“Concrete is indispensable. There’s no question about that,” says Stringer, who lives near the Colacem site.In many ways, he exemplifies our relationship with concrete, the second most consumed product in the world, after water.We depend on it — but it’s harming our planet.The London-based Chatham House think-tank and the International Energy Agency say more than 4 billion tonnes of cement produced worldwide each year is responsible for about 8 per cent of global CO2 emissions.By comparison, iron and steel account for 4 to 7 per cent of C02 emissions, according to the European Commission. The burning of fossil fuels such as coal, oil and gas is responsible for t ...
