Sažetak:
The aim of this work was to compare and evaluate composting efficiencies of originally wet (OWT) and pre-dried (PDT) tobacco solid waste from cigarette manufacturing. The effect of drying on the biodegradability of the tobacco waste was also investigated. OWT with moisture content (MC) of 75.7 % was dried on a tray at ambient conditions for 23 days and resulted as PDT. Before composting, water was added to the PDT and the MC of the starting material was set to 60 %. Composting experiments were conducted in a thermally insulated column reactor with working volume of 24 L. The substrate inside the reactor was forcefully aerated at airflow rate of 1.5 L min-1. During the composting, as well as drying experiments, pH-value, C/N ratio, organic matter content (OM), MC, and nicotine content were determined at preset times. At the end of the drying experiment 0.096 g of OM was degraded per 1 g of initial dry matter (gOM gDMinit-1). The composting experiments with OWT and PDT were conducted for 27 and 13 days, respectively, while 0.434 and 0.449 gOM gDMinit-1 were degraded, which showed higher efficiency of the process where PDT was used as a composting substrate. During the drying experiment about 50 % of nicotine was degraded while nicotine was completely degraded at the end of both composting experiments. The biodrying process could be recommended as a pre- treatment of wet tobacco solid waste intended for composting but further investigations are needed on the process performance and optimization.
