Reducing emissions

Many different sources of emissions exist in cement manufacturing. There is no such thing as an emission-free plant, but by using modern filter technologies, innovative production methods and process-integrated environmental protection, we have been able to substantially reduce the adverse effects on people and the environment.

Our goal: Continuous improvement

On the one hand, we are optimising production processes by reducing the specific energy consumption of the kiln line and the emissions associated with it thanks to extensive modernisations. In 2005 we achieved a level of level of 3,6 GJ/t clinker. On the other hand, we are investing in post-production environmental protection, i.e. in exhaust gas purification facilities by replacing old filters with new ones.

In 2005, 54% of the clinker was produced in kilns with continuous measurement equipment.

HeidelbergCement commitment on emission reduction targets

HeidelbergCement has committed itself to Sustainable Development. As member of the Cement Sustainable Initiative of the World Business Council for Sustainable Development we have set the following Group targets to reduce our combined emissions to air.

In the area of climate change we intend to reduce our specific net CO2 emissions by 15% (per tonne of cement) in 2010 compared to the level of 1990. This commitment was made in 2003.

In addition, we are aiming to reduce dust, NOx and SOx- emissions. The Group intends to reduce the specific emissions (per tonne of clinker) by 2012 compared to the 2000 level:

• for dust by 50%
• for NOx by 20 %
• for SOx by 30% .

To achieve these targets in 2012 HeidelbergCement will continue with our efforts to reduce emissions by:

• Continued improvement of process integrated measures
• Upgrade of existing emission control installations
• Investment in new installations

We can already demonstrate considerable successes in reducing emissions. In 2005, the dust emission was reduced by 32% compared to 2000. For NOx and SOx we have already achieved a reduction of 13 % and 22% respectively.

We will report on the progress made compared to the targets on a yearly basis.
