Fuel consumption increased by1 points in France and Turkey, by more than 5 pointsin the United States and by more than 6 points inSenegal. In total the proportion of alternative fuels,excluding Kazakhstan and India, was 15.5 % in 2010,compared with 13.6 % in 2009.Several ongoing projects will continue to increase theuse of these alternative fuels :• In Turkey, a joint venture subsidiary establishedwith Chimirec has obtained the necessary authorizationsand has begun to supply the Bastas plantwith waste in a program which is expected to growover the coming years.• In Senegal, the program to use of a range of fuels(peanut shells, Jatrophas berries, used oils, tires,solid waste) is to be extended to the kiln n° 5.• In Switzerland, the factory has begun to use milledwood from construction site materials recoveredby the Concrete and Aggregates business, thusdoubling the proportion of biomass fuel used from14 to over 28 %.8.2.3. Pollution controlIn addition to the above measures in relation to quarries, the Group is reducing environmental pollution caused byindustrial operations. Emissions and discharges into the air relate primarily to the cement factories. These are measuredon a regular basis and are strictly regulated and monitored, in particular with regard to dust, SOx and NOx.Emissions of pollutants are measured on a regular basis and action plans put in place to reduce these.
