Cement and Non-Metallic Mineral (Plastics and Chemicals)

Product innovation require energy-efficiency focus
Cement, one of the oldest construction materials, is also among the newest and most innovative. Canada uses about 31.2 million cubic metres of concrete per year -- one cubic metre per person --, in a wide variety of construction projects. Research continues to make cement more versatile and adaptable, widening the range of uses and improving properties, such as strength, electrical conductivity, and even pollution control.
New products include cork-cement composites, mudcrete for road bases and land reclamation, glass concrete for aesthetics, rubberized concrete, polymer concrete, geopolymer green concrete, limecrete, strong and light hempcrete with good insulation properties, papercrete and smog-eating concrete. There are six quarries and seven modern processing plants in southern Ontario. Combined, the companies have 11 cement kilns with a total clinker production capacity of more than eight million tones per year.
The cost of energy as part of the total production costs in the cement industry is significant, warranting increased attention to energy efficiency and its impact on the bottom line.
The non-metallic industry includes establishments that primarily mine, quarry, mill, or otherwise prepare non-metallic minerals, except fuels and shaping natural abrasive stones at the quarry. Also included here are establishments that primarily produce blast, grinding, or polishing sand.
Consider the benefits of reaching your energy-efficiency goals:
  • Long-term, reliable energy reductions
  • Process and productivity improvements
  • Industrial competitiveness and environmental attributes
Opportunity Areas:
  • HVAC
  • Process heat
  • Machine drives
  • Electrochemical
  • Process specific
  • Cooling and refrigeration

Energy initiatives deliver savings

Typical projects could include:

  • Retrofitting pumping systems
  • Improving the energy efficiency of your kiln, which, in turn, saves electricity
  • Installing variable speed drives for fan or pumping systems such as a variable speed inlet vane damper in a coal mill
  • Installing intelligent systems such as improving kiln response times in changing operating conditions which in turn saves electricity
  • Making improvements to process technology which could include roller mills and reciprocating grate coolers
