Options and limitations in NOx abatement in the cement industry, Part 2

For almost 20 years the German cement industry has been dealing with the pr oblem of NO, emissions and the industrial options for reducing them. There has been a continuous decrease for a number of years in the proportion of t he total NOx emissions in Germany which can be attributed to the cement ind ustry but it continues to remain at the focal point of politics because of the large stationary sources of emissions. Regulation of NOx emissions from the cement industry is determined al legislature but also by political dev elopments on the European level. Particular mention should be made of the d escription of "Best Available Techniques" for the cement industry and the a doption of the European Incineration Directive at the end of 2000. This art icle describes the latest developments with respect to the industrial optio ns for NOx abatement and the investigations carried out by the Research Ins titute of the Cement Industry in this connection.
