  1. Pollution Probe’s Energy Systems WorkshopChallenges and Opportunities for the Cement Industry • February 9th, 2011 • Luc Robitaille, Corporate Director Environment • Holcim (Canada) Inc. © Holcim (Canada) Inc.

  2. Holcim (Canada) Inc’s Operations • 2 Cement Plants (Joliette and Mississauga) • Demix (QC) and Dufferin (ON) operations • Concrete plants • Aggregate facilities (quarries & pits) • Asphalt plants • Construction divisions © Holcim (Canada) Inc.

  4. Our Products • Cement is: • the glue that holds concrete together • a dry very fine powder • sold in bulk or bags • manufactured throughout the world • easy to ship long distances • Concrete is : • 2nd most used product on the planet • after it sets, it takes on very beneficial properties • produced locally • hauled over short distances 4 Both Cement and Concrete Are Essential to North America’s Economic Sustainability

  5. Pollution Probe’s Energy Systems Model

  6. Looking at Holcim’s Manufacturing operations… Cement Concrete Drying Calcination Grinding Fuels

  7. Looking at Holcim’s products… Housing Infrastructure Transport Thermal Mass Reflectivity Durability Energy

  8. Cement production requires large amounts of energy Emissions (CO2, NOx, SO2, Dust…) Raw Material Extraction (limestone, shale, bauxite…) Transport Fuels & Electricity Coal, Coke, others gypsum

  9. Worldwide demand for cement is predicted to grow in the next 20 years by 50% to 80% 9

  10. Energy flow for the cement industry…the traditional view

  11. The data presented is derived from various Benchmarking Studies (CAC, WBCSD, CIPEC, IEA)

  12. The industry relies principally on Coal and petcoke

  13. Most of the Energy is used in the Calcination Process

  14. Source: WBCSD CSI “Getting the Numbers Right”, 2008 Thermal energy efficiency improvement potential There is between 9 % and 88 % difference in thermal energy efficiency between different clinker kiln technology types But within each kiln technology type there is very little improvement of efficiency from 2000 to 2006 • The potential for energy efficiency improvement of existing installations is very small. • Improving thermal energy efficiency requires asset renewal and investments in new kilns.

  15. The Canadian Cement sector has already invested in Energy Efficiency Processes More efficient

  16. Similar data has been reported by the WBCSD - CSI

  17. Energy flow for the cement industry…the Sustainable Model

  18. Average 865 kg CO2/t 815 kg CO2/t The CO2 improvement potential through thermal energy efficiency is very limited Source: WBCSD CSI “Getting the Numbers Right”, 2008 • If 90 % of the clinker capacity in the EU27 would be renewed or upgraded to the most modern technology, then the cement EU27 CO2 emissions would decrease by only ~5 %, at a costof ~60 €/ton CO2.

  19. Pollution Probe has looked as Biomass as part of the Solution But… and…

  20. For more than 20 years, the cement industry has been using an under-valued and sustainable source of energy

  21. Energy Substitution • Every tonne of coal replaced with a cost-effective, low carbon substitute (biomass) energy source will avoid approximately 2.5 tonnes of CO2 emissions from cement manufacturing.

  22. Alternative fuels have been recognized as an essential part of the waste management hierarchy in Europe… and in Quebec where it is classified as a “recovery” operation and not as disposal

  23. Canada (except Quebec) has been lagging leading jurisdictions in “extracting” energy and materials from a “wasted resource”

  24. The conditions in a cement kiln are well suited to the co-processing of residual materials • Extremely high temperatures • Flame To= 1850 oC • Solid To= 1450 oC • Residence time • Kiln Gases = 4 - 20 sec • Materials = 10-15 min • No residues

  25. Energy flow for the cement industry…the missing opportunity

  26. Looking at Holcim’s products…and how they are used… Housing Infrastructure Transport Thermal Mass Reflectivity Durability Energy

  27. Concrete is a Strategic Resource that is Used Everywhere • Roads • Bridges • Public Transport • Public Infrastructure • Housing 27 27

  28. Concrete is a strategic resource essential for our society’s move toward a Green Economy • Wind Power • Hydroelectricity • Nuclear • Green Roofs • And even Solar Energy

  29. Going Back To the energy primer… What we really want Housing, comfort Transport, access Convenience Services infrastructure ENERGY STORY NO. 1 JASON AND SHANNON RENOVATE THEIR HOME

  30. Let’s look at housing in a more sustainable way Work completed by the ATHENA Institute for the international Green Building Challenge demonstrates that over the lifetime of a building, operating energy has a far greater impact than embodied energy. The embodied energy of the materials, in this study, represents only 3 to 13 percent of total energy use over a 75 - 80 year building life. Source: Scott Horst, ATHENA Institute

  31. Concrete Homes and Buildings use on average 40-50% less energy for Heating and Cooling The January 2009 utility bills for one of the families in their new three-story home totaled a lean $50. Concrete tubes at the Earth Rangers facility in Woodbridge, ON Net-Zero Home

  32. Significant gains are also possible in transportation The greatest increase in road traffic in recent years has been from heavy trucks

  33. Concrete pavement is a “rigid” surface which leads to potential fuel savings of 2-4% for heavy trucks In addition, a significant amount of embodied energy is present in asphalt and rubberized asphalt pavement The high reflectivity of concrete pavement allows for the use of lower intensity lighting and reduces urban heat island impacts

  34. Permeable concrete pavements also offer a more efficient and sustainable solution for the management of stormwater Permeable Pavers Or Permeable concrete
