- The article describes an experiment conducted under industrial (real) conditions in a municipal waste composting facility. The waste gases emitted from composting processes were passed through an experimental installation built in a semi-technical scale. The installation consisted of two biofilters which were filled with different aluminosilicate beds with average granulation of 4–10 mm. The sorbents were inoculated with a mixture of microorganisms bred on the mineral bed, previously operating in the tank with the waste from that composting facility. Malodorous gases were passed through the installation and concentrations of organic acids and aldehydes before and after passing through biofilters with the examined sorbents. The aim of the experiment was to determine which of the two mineral sorbents better removes the analysed contaminations from post-production gases. The experiment lasted for a month, as difficult and highly variable industrial conditions caused problems with operation and the experiment was suddenly interrupted. The study will be continued after the introduction of design changes in the installation. After the month of conducting the study it can be conclude that in the first weeks of the study, before the dampness of sorbents took place, halloysite reduced the concentrations of acetic acid in 80–99%, and of acetaldehyde in 96–98%. The other aluminosilicate caused a drop in the concentrations by 97–98% and 92–86%, respectively. Moreover, in the experiment planned in the semi-technical scale, it was not possible to determine the overall performances of mineral biofilters due to unstable operating conditions and ending the experiment prematurely. The halloysite sorbent finally turned out to be potentially the more efficient than the other aluminosilicate sorbent.
