The effects of the application of biotechnological additives on the emissions of
ammonia, carbon dioxide, nitrogen oxide and hydrogen sulphide were monitored. The
experiment revealed that by using biotechnological additives, a reduction in the
emissions of all the aforementioned gases can occur and in case of ammonia, by an
average of 30%.
Immediately after the application of some additives, there was an increase in
emissions followed by a reduction. The effect may be used in biogas production.
Selected biotechnological additives may be also applied in aerobic controlled highspeed
composting. The additives stimulate thermophilic 6 bacteria into greater activity
and propagation, which accelerates the entire composting process. At the same
time, they suppress emissions, especially of those of noxious smells.

Note: The table contains the most frequently used and the most efficient biotechnological additives.
In the Czech Republic, SEKOL – JALKA is produced. It reduces ammonia emissions by up to 32%.
4.2 | Spraying technology
Spraying technology treats air in livestock stables, meat-processing facilities, in
the leather and textile industries, sanitation companies, in waste water treatment
plants, etc. Air in these facilities is polluted by sulphur gases, ammonia and other
malodorous substances. Water with a special concentrate that decomposes air-borne
