Germany and the use of alternative fuels

The use of alternative fuels is highest in Europe, where we have made significant investments in retrofitting our facilities. Germany leads the way in the use of alternative fuels, and this country's cement industry provides an important waste disposal route.

CEMEX Germany has worked for many years to reduce the consumption of fossil fuels by replacing them with alternative fuels. In 2010, the average substitution rate for our operating kilns at our Rüdersdorf and Kollenbach cement plants was 74%. This means that both plants burned more than 414,000 tons of alternative fuels, resulting in a net reduction of 337,000 tons of CO2.

With this result, CEMEX Germany is number one among CEMEX operations worldwide in the use of alternative fuels. In addition to the most popular RDF (refuse derived fuels), several other alternative fuels are being used, such as tire chips, dried sewage sludge, and animal meal.

In 2011, a sophisticated project will start in the Kollenbach plant in order to ensure a smoother kiln operation due to better homogeneity of the ground fuels. This will further reduce CO2 emissions and save natural resources.

For further information about our use of alternative fuels, please read CEMEX’s position paper on alternative fuels.
