Sažetak
A pilot-scale composting of tobacco waste was conducted in two thermally insulated reactors to determine the effect of intermittent stirring on the composting performance. Two experiments were carried out in a 240 dm3 packed bed reactor at airflow rate of 0.65 dm3min-1kgVSinitial-1 ; the first experiment was carried out without stirring (PBRNS) ; during the second experiment substrate was periodically manually stirred (PBRS). The third experiment was conducted in a 200 dm3 horizontal reactor with stirrers (HRS) at airflow rate of 0.38 dm3min-1 kgVSinitial-1. Substrate was automatically agitated every 24 hours for 1 minute at the stirring rate of 6.3 rpm. During the composting in PBRNS there was a significant temperature distribution over the bed height. At the end of the processes in PBRNS, PBRS and HRS conversions of the volatile matter were 50.6% (at 38. day), 53.0% (at 28. day) and 51.1% (at 29. day), respectively, showing that stirring increases the degradation rate.
