Empirical Model of Thermophilic Phase of Composting Process

Tomasz Jakubowski

Abstract

Progress of composting process depends on properties of feedstocks and conditions of decomposition. Factors influencing this process include most of all temperature of composting material, air temperature, feedstock humidity and structure, carbon-to-nitrogen ratio (C/N) and organic matter content in feedstocks. The aim of the present study was to elaborate a model characterizing the pattern of temperature changes in thermopilic phase of composting of dead poultry depending on the structural material used. The studies were conducted in a chicken (Gallus gallus domesticus) farm. Compost bins used in the experiment were equipped with perforated bottoms. Five types of straw were used as structural material in the composting process: wheat, oat, barley, rape and corn. The regression model computed in this study predicts temperature changes in the composting material exact to nearly 95% and the predicted values do not statistically significantly differ from empirical values.
