BACKGROUNDCement Sustainability Initiative (CSI)
1999, CSI Project Initiated Under the Auspices of the World Business Council for Sustainable Development (WBCSD)
Leading Worldwide Cement Producers Focused on Understanding, Managing & Minimizing the Environmental and Social Impacts of Cement Production:
LAFARGECEMEXHOLCIMHeidelbergOTHERS—18 Cement Companies are participating gtoday in the CSI Project
The WBCSD retained in 1999 Battelle Memorial Institute to Identify the Major Sustainability Topics in order to Position the Cement Industry for a More Sustainable Future

BACKGROUNDCement Sustainability Initiative:
Battelle’s final report, “towards a Sustainable Cement Industry” was released in April 2002. It identified eight major topics that would shape the cement industry’s path towards a more sustainable future in the next 20 years:
Improve eco efficiencyImprove eco-efficiencyClimate protectionEmission reduction, i.e., dust, NOx, SOxEcological stewardshipLocal community well beingRegional developmentg pCreating more shareholder Value
The Participating Companies Responded to the Battelle Scoping Report by Launching in 2002 an “Agenda for Action.” The Core CSI program Included:
Climate ProtectionFuel & Raw Materials UseEmployee Health & SafetyAir Emissions ReductionLocal ImpactsReporting & Communications

BACKGROUND
Cement Sustainability Initiative
Each Agenda for Action Topic was Divided Into:
- Industry Actions, i.e., a protocol to calculate a CO2 i i i t dCO2 emissions inventory, and
- Company Specific Actions, i.e., setting CO2 mitigation targets

Some Definitions: What is Recycled Concrete ?“EUROPEAN ”
Source
Rubble from concrete structures demolition (building, curbs, pipes…)
Leftover concrete (RMX concrete not used on a job)
Product
Crushed into aggregatesgg g
Can meet different specifications
Applications (substitute to virgin aggregates)
Road base or parking lot base
Back fill and structural fill for building applications
