What are sustainability issues?

Sustainability is more than the high-profile issues of CO2 and climatechange; also included are the social, environmental, and economic(SEE) aspects of:

• Land• Water• Energy• Emissions (atmosphere)• Non renewable Materials and Resources• Indoor environmental quality

Content: The three P’s

People : To communicate and establish a culture of “Sustainability” throughKnowledge transfer just like “Safety first” and the promotion of performancespecifications

Process: Durable Concrete is a Process. We must identify all barriers andeliminate them. We must facilitate the use of alternate materials to replacenon renewable resources. And promote efficiency in ManufacturingDelivering, and Application of Durable Quality concrete

Product Innovation: To create an environment that is conducive to innovation,value creation, and the ability to sustain successful utilization ofsustainable material such as Composite Cements and or concrete with highcontent of “Mineral Component”

WBCSD Cement Sustainability

In 1999, ten leading cement companies –representing one-third of the world’s cementproduction – embarked on the CementSustainability Initiative (CSI), a member-sponsoredprogram of the WBCSD.

In 2008 18 member countries, including 8 of largest top ten

The objective was to find new ways to meet the sustainability challenge of:

4 reducing the industry’s ecological footprint4 increasing stakeholder engagement4 understanding the industry's social contributions.

Cement production is energy-intensive - it accounts for 3.8 to 5 percent of global carbon dioxideemissions - and it touches on a wide range of sustainability issues including:

4 Climate change4 Pollution4 Resource depletion4 Worker’s health and safety

16


Cement Sustainability Initiative

4 Holcim: 80% of 1990 per-unit emissions by 20104 LaFarge: 80% of 1990 per-unit emissions by 2010; 90% of 1990 absolute

emissions by 2010 in industrialized countries4 Cemex: 75% of 1990 per-unit emissions by 20154 Heidelberg: 85% of 1990 per-unit emissions by 20104 Titan: 85% of 1990 per-unit emissions by 2010

Product Innovation

22


The Sustainable Attributes of Concrete

locally derived- produced- placed and can be recycledas aggregate

once in place consumes CO2 from the atmosphere

is non toxic

is generally reinforced by 100%- recycled steel andgenerally incorporates other industrial by-products

is resource efficient: the ingredients require littleprocessing and generate little waste

is exceptionally strong in uses where resistance to fireprogressive collapse- seismic disturbance or blast areconcerned

23


The Sustainable Attributes of Concrete

in roadways- reduces rolling resistance and thus fuelconsumption

can be made pervious to water- thus preventing run-off

is reflective- therefore cool- safe and saves on artificiallighting

is exceptionally durable when properly designed andplaced to last a century or more

provides excellent thermal mass that can enablesubstantial reductions in heating and cooling costs

has natural beauty in architectural applications

Provides great flexibility in design options

24


Today’s Challenges

Concrete industry is fragmented and diverse

Limited acceptance of new performance standards

Slow to investigate and adopt new technology

Reluctance to change

Gap in product knowledge

Sustainability in Cement Manufacturing

Efficient Management of our Non Renewable Mineral Resources

The Use of Byproducts from Industry

US cement mfg. accounts for < 1.5% of man-made CO2

World Cement Mfg. accounts for 5% of man-made CO2

CO2 from:

4 Material decomposition CaCO3 → Calcination→ CaO → CO2

4 Fossil fuel consumption

Efficiency in the Pyroprocess

The Use of Alternate Fuel

The Use of Byproducts as SCM

Holcim internal goal “0” Solid Waste Landfilled by 2012

Impacts of the cement production process

Quarrying and raw materials preparation

consumption of non-renewableresources

impacts on local landscape, ecologyand communities

Clinker production

use of fossil fuels

atmospheric emissions,especially CO2

Cement grinding anddistribution

use of raw materialsand electricity

can have impacts onlocal communities

Cement production is an energy and resourceintensive process.

Today’s Kilns

The cement kiln is one of the largest piece of movingequipment in the world

Kiln flame 3400°F (1870°C ) ⅓ the temperature of thesun surface

Raw meal in the kiln melting at 2700°F (1480 °C)

Average kiln today produces 60 to 70% more clinker atless than half the energy

“Wet process” 254 plants (1970) down to 54 plants77% reduction

81% of US production is “Dry Process”

63


Drivers of CO2 reduction

64


Alternate Fuels - Tire Derived Fuel

Pound for pound, scrap tires have about 25%more energy than coal

Tires are also a raw material source for iron (steelbelts)

Can have lower NOx emissions compared tosome types of coal

Rubber Manufacturers Association reports that thecement industry consumed 53 million tires in 2004

(41% of total burned)
