Reducing Energy Consumption
Canadian cement manufacturers are highly motivated to maximize the energy efficiency of their operations. Electricity and fuels costs amount to nearly 40% of total cement manufacturing costs.
The primary factor determining the efficiency of plant operations is the age and type of kiln technology used. In this regard, Canadian cement mannufacturing operations are modern and efficient, with over 55% of current cement production capacity built since 1980. The modernization of the Canadian cement industry has led to a remarkable 16% improvement in overall energy efficiency.
After kiln technology, plant energy efficiency is most affected by the complex interaction of numerous factors relating to energy management practices, other (non-kiln) installed equipment, and plant operating practices.
Critical Areas Influencing Overall Energy Use
The Cement Association of Canada, in partnership with Natural Resources Canada's Office of Energy Efficiency, commissioned the Canadian Cement Industry Energy Benchmarking Study to assess the industry's performance in these three critical areas influencing energy use, and to identify and help guide further energy efficiency improvements. This three-part study is the first for any industry sector in Canada, and the only review of its kind of a national cement industry anywhere in the world.
The Canadian Cement Industry Becnchmarking study concluded that the overall energy efficiency of the cement sector was relatively high, with a median energy efficency index of 76 compared to the theoretical best practices plant with a value of 100. Nine of the 15 facilities achieved a "good practice rating" index of at least 75. Despite this strong performance, the study identified areas that have the potential to yield further energy efficicency and cost savings benefits for the sector.
