Abstract
One of many environmental problems of poultry farming enterprises is the emission and spread of unpleasant smell over long distances. The odours significantly reduce the living standards of the population near the poultry farm. Odour occurrence in poultry houses is caused mainly by decomposition of bird waste such as faeces, urine, feathers mixed with bedding material and dust. The percentage of ammonia was the highest (95 %), methane and dust were significantly lower (3 % and 2 %, respectively). In the paper, we described a biological air filtration unit bioscrubber and estimated its economic efficiency.
