(57) The invention relates to a device and a method for producing fertilizer from the exhaust gases of a production system, for example a system for producing cement. The exhaust gases are completely converted such that the exhaust gases are not released into the environment. For this purpose, the exhaust gases are introduced directly into the device from the production system. Exhaust gases such as NO_x and/or SO₂ are first oxidized in said device and then reprocessed into NH₄NO₃ or (NH4)₂SO₄. CO₂ is reprocessed into NH₄HCO₃ in the device while nitrogen is converted into ammonia, and ammonium, among others, is used to produce NH₄HCO₃ from CO₂.
