Summary:

The article presents the characteristic features of the process of composting with animal waste share. The investigation on composting animal waste have been conducted since 2006 in a chamber composting plant belonging to “Beskid Ltd.” at Żywiec that operates on the Herhof technology. The composting process consists of two stages: intensive composting in a bioreactor and seasoning in heaps. Components used for composting process are biodegradable waste from household, green waste (grass, leaves) and waste from a Slaughterhouse S.A. at Żywiec (bones, skins, meat fragments). The composting process with participation of the materials mentioned underwent assessment both during its bioreactor stage (temperature of the matter as a parameter indicating the intensity of biochemical processes, chemical composition of the matter) and during seasoning of the compost in heaps (sanitary state after unloading the bioreactor, temperature of compost prisms). After ending of the composting process, the compost with animal waste share was evaluated with respect to all the parameters characteristic for organic fertilizers.
