This is a partial summary of the Holcim Community Advisory Panel meeting, Feb. 2011.  The President & CEO of Holcim Canada presented an overview of the Mississauga Plant’s Operations.

-Holcim  will soon celebrate 60 years of operations in Canada (1954 in Quebec, 1956 in Ontario)

-over past 10 years, more that $100 million have been invested at the Mississauga Plant, in support of  PM 2.5 and 10, NOx , SO2 and CO2 emission reduction efforts

CO2 Emissions:

–       since 1990, the net production of CO2 per tonne of cement has been reduced by 30%

–       approx. 60% of CO2 emissions from the cement sector result from the chemical process that converts calcium carbonate in limestone to calcium oxide during the production of clinker

–       by using suitable industrial by-products, such as slag from the steel industry,  this chemical reaction and resulting GHG emissions are minimized

–       Mississauga plant spent $88 million on a Vertical Roller Mill (VRM) to produce a slag cement, resulting in reduction of clinker and CO2 emissions

PM10, PM2.5:

–       Holcim Canada recognizes  concern that emission of fine particulates are concern in Clarkson airshed

–       Installed Teflon Bags in system baghouse; these state-of-the-art bags are rated to achieve control of PM1 (ultrafine particulates) – led to 79% reduction in PM, PM10 and PM2.5 from 2006 to 2009 (phased in installation)

Recent emission reduction initiatives:

–       fugitive dust control

–       road paving

–       installation of water sprinklers

–       use of water, vacuum and sweeper trucks

–       dry fog water spraying

–       installation of a wet dust suppression system

–       dust spray on off-loading stone

–       greening of the Plant through tree plantings

As a member of the Southwest GTA Task Force, Holcim makes recommendations to improve the quality of the Clarkson Airshed.

Holcim promotes that the Ontario GHG policy should incorporate the following:

–       A uniform CO2 intensity standard should be adopted.  Should be expressed in a form that recognizes the important role that supplementary cement substitutes play in reducing Greenhouse Gas (GHG) emissions from cement manufacturing

–       Encourage the use of alternative energies from biomass, engineered fuels, residual material and other combustible by-products

–       Aggressive adoption of the new National and Ontario building code standards (release in Q1, 2011), that allow for less use of carbon intensive cementitious material.
