Composting of Waste from Poultry Breeding – Biological Analysis

T. A. Marcinkowski

Abstract
The objective of this study was primarily to determine the course of biological composition changes of wastes during composting. Here presented are the results of the bacteriological, mycological and parasitological composition analyses of composts consisting of: goose and broiler excrements from ecological farms, remainders of goose intestines from slaughterhouses, goose feather waste collected on the sieves of the farm wastewater treatment plants, as well as sewage sludge from slaughterhouse wastewater treatment plants and poultry processing plants. Ground pine bark, pine shavings and rye straw chaff was used as an addition to the composting mixture. The investigation of the composting process in static piles lasting 120 days was carried out in winter conditions in the area near the aforementioned wastewater treatment plant of an industrial complex situated in Lower Silesia (the south-western region of Poland), the complex specializing in breeding, slaughtering and processing of poultry.
