Sažetak:
Two major gaseous byproducts of microbial transformation during aerobic biodegradation of solid waste are carbon dioxide (CO2) and ammonia (NH3). As is well known that CO2 is the greenhouse gas and NH3 is a noxious, toxic gas. It is important to find ways to efficiently control and remove these gases from waste gaseous streams. The purpose of this work was to investigate sorption of ammonia and carbon dioxide on zeolite during composting of winery and tobacco waste mixture. Composting experiments were carried out with forced aeration in thermally insulated packed bed reactor (10 dm3 of working volume) during 16 days. During the process, temperature changes in the reactor were continuously monitored and evolved CO2 and NH3 in the gaseous stream, pH value, C/N ratio, volatile solids content and mesophilic and thermophilic microorganisms in the composting mass were determined periodically. At the end of the composting process 54% of volatile solids were degraded and zeolite showed good efficiency in sorption of ammonia as well as of carbon dioxide.
