“…a-Pinene was 1 order of magnitude lower than D-limonene, and b-pinene was not detected during the entire biotreatment process. The detected predominant compounds of ketones and terpenes agreed with previous studies of typical emissions produced during the aerobic degradation of MSW (Bruno et al, 2007;Eitzer, 1995;He et al, 2010;Smet et al, 1999). Among the four MSCs, the highest concentrations of methyl mercaptane, dimethyl sulfide (DMS), and dimethyl disulfide (DMDS) were on the same order of magnitude, 58.5, 44.6, and 88.4 mg/m 3 , respectively, whereas the highest concentration of dimethyl trisulfide (DMTS) was 1 order of magnitude lower than the three aforementioned compounds.…”

Because volatile organic compounds (VOCs) are one of the main concerns during municipal solid waste (MSW) treatment, the release patterns and the environmental effects of VOCs were investigated during laboratory-scale aerobic biotreatments of MSW with continuous and intermittent negative ventilation. When the same airflow amounts were used, intermittent ventilation was found to reduce the total VOC emissions from continuous ventilation process by 28%. In this study, 23 types of volatile organic compounds were analyzed, of which butyraldehyde, ethanol, and butanone were emitted in the highest concentrations of 748, 372, and 260 mg/m 3 , respectively. During the aerobic biotreatment process, ketones, aldehydes, and alcohols were primarily released during the first 4 days, accounting for 86À98% of the total VOC emissions during this period. The emission concentrations of malodorous sulfide compounds displayed two peaks on day 4 and day 9, with the contribution to the total VOC emissions being enhanced from less than 10% to 76À83%. The release of terpenes and aromatics lasted for more than 10 days with no significant emission peaks and the proportions of those compounds in the total VOCs increased gradually, but no more than 50% even at the end of the process. Considering the strength of the odors, aldehydes were the predominant contributors at the beginning of the experiment, whereas malodorous sulfide compounds became the most odorous compound as the biological process continued. Most of the VOCs emitted at the concentrations beneath the level causing health threat to the workers.Implications: In aerobic biotreatment plants of MSW, volatile organic compounds (VOCs) are among the major pollutants in exhaust gases. Understanding the emission patterns of VOCs (e.g., identifying the dominant VOC components during the different biotreatment stages) are of importance for VOC control and treatment, and can also provide a new index to evaluate the different biotreatment operations. This paper is of interest to scientists, the operators of MSW biotreatment plants, and those concerned with odor management practices.

“…10 Odor is one of the most important problems for waste management plants. 13 The analytical difficulties in odor measurements are related to the high number of volatile components, especially when concentrations are lower than their detection limits. 13 The compounds are sampled with thermal desorbable radial diffusive samplers with Radiellocontaining Tenax cartridges.…”

“…Under aerobic conditions, the predominant volatiles are alcohols, ketones, esters, organic acids, and hydrocarbons, particularly toluene and ethylbenzene (Komilis et al, 2004;Pagans et al, 2006;Rodriguez-Navas et al, 2012). Dimethyl sulfide, dimethyl disulfide, limonene, and a-pinene are the major compounds that have been identified as emissions during the composting process (Scaglia et al, 2011;Rodriguez-Navas et al, 2012), although emissions may vary according to the type of residue, the state of decomposition, and the operating conditions of the process (Bruno et al, 2007;Shen et al, 2012). The production and emission of odorous or dangerous compounds is one of the greatest disadvantages of composting (Pagans et al, 2007).…”

The aim of this article is to estimate the volatile organic compound (VOC) concentration in the air inside a composting pile based on their concentration in the compost and applying gas-liquid-solid equilibrium calculations. Gaseous and solid samples from a composting process were taken, and it has been proven that analysis of the solid samples permitted the determination of a larger number of VOCs (in a 40:1 ratio). Of all the VOCs found, monoaromatic hydrocarbons represent a higher risk to health because of their concentrations and persistence. Concentration of these compounds in the air inside the pile was estimated by phase equilibrium calculations, and establishing the hazard ratio leads to results very similar to those obtained in gas-sample-based studies. These findings confirm the existence of a health risk for compost facility workers through exposure to xylenes.
