(57) In the method according to the invention for producing cement, initially in a cement clinker process cement clinker is produced from cement raw meal to form a pollutant-containing offgas. The cement clinker is subsequently milled into cement in a cement mill in a cement milling process. Here at least some of the offgas formed in the cement clinker process is admixed with pozzolan to bind pollutants and said pozzolan is subsequently separated in a filter as pollutant-enriched pozzolan. Subsequently at least some of the pollutant-enriched pozzolan is added to the cement clinker upstream and/or downstream of the cement mill.
