Emission of Volatile Organic Compounds during Composting of Poultry Litter

Abstract: The objective of this study was to identify and quantify volatile organic compounds (VOCs) produced during composting of poultry litter. The VOCs produced from in-vessel composting with a controlled aeration system were tested using the F-ITR method by VOC analyzer. Alkanes and alkylated benzenes were emitted in the highest amounts from poultry litter, while aldehydes, terpenes, ketones were emitted in much lesser amounts. Studies showed that VOCs generation was the greatest early during the composting process… Show more

“…5, the concentrations of short-chain fatty acids (C2-C5) increased sharply during the initial composting stage in all treatments, but dropped off dramatically on the fifth day of composting. The result was agreement with other researches [36]. There was coincidence between high short-chain fatty acids (C 2 -C 5 ) emission and high process temperature, which is the period of maximum activity.…”

“…1, initially the temperature increased as a consequence of the rapid breakdown of the readily available organic matter by microorganisms. As the organic matter became more stabilised, the microbial activities and the organic matter decomposition rate decreased and the temperature gradually decreased to ambient Brought to you by | MIT Libraries Authenticated Download Date | 5/9/18 4:42 PM levels, marking the end of the thermophilic phase [14]. The maximum temperatures higher than 55°C are necessary to destroy pathogen microorganisms, but temperatures of 45-55°C must be maintained for maximum biodegradation [12].…”

“…In the untreated control process, S0, the maximum temperature was only 348C. This may be due to the high moisture content of municipal solid waste, which can create anaerobic conditions that do not permit the growth of aerobic thermophilic microorganisms [22]. During the initial phase of composting, the pH dropped in the processes due to the high concentrations of organic acids.…”
