“…However, it has also to be considered that OU calculated using the presented methodology in a previous study were in the range of 1200-28,000 OU [3], in accordance with OU calculated using dynamic olfactometry (5000-30,000 OU m -3 ) in similar facilities [9,10]. Additionally, several studies have demonstrated good correlations between olfactometrically determined OU and VOC concentrations [5,10,11]. The use of the presented procedure is advisable to be used when comparing differences in the odorous charge when changes in the processes developed into the facility are implemented [3].…”

“…It has to be taken into account that possible effects derived from masking or synergies between the evaluated compounds are not considered, and that the total odour units (OU) determined by olfactometry could differ in a certain way [5][6][7][8].

“…Esto se corrobora con el número de publicaciones relacionadas con el análisis de ciclo de vida-ACV de los biorresiduos (8 publicaciones) y con los estudios enfocados en minimizar las emisiones de compuestos orgánicos volátiles (8 publicaciones), líneas que han llamado la atención debido a la generación de olores, emisiones gaseosas e incidencia de las variables fisicoquímicas sobre el proceso [42][43][44].…”

“…En contraste, pocos estudios han considerado el efecto conjunto del ajuste de diferentes parámetros (i.e. aireación, relación C/N, humedad) que ayuden a comprender la dinámica del proceso con una mayor aproximación [42][43][44]. El desarrollo de este tipo de investigaciones, soportados en estudios cinéticos del proceso y en la incorporación de herramientas como las redes neuronales o algoritmos genéticos, pueden contribuir a la construcción de modelos empíricos que describan el comportamiento del proceso, predecir calidad del producto y definir las condiciones operacionales más adecuadas.…”

Biowaste is the main fraction of MSW in developing countries. Composting is a promising alternative for the management of biowaste in these contexts. However, its implementation has not been effective in developing countries, for which it is necessary to explore options to improve its application in this context. This article reviewed the research trends on biowaste composting and the potential application in developing countries such as Colombia. For this purpose, the technology monitoring methodology was used in databases of specialized scientific journals (period 2006 to 2017), using bibliometric tools such as RefViz® and Tlab®. The research has focused on optimizing the process through measures such as the use of amendment or support materials, strategies for reducing nitrogen losses, aerobic biodegradability studies and the development of empirical models to predict process conditions. The integration of this research in the context of developing countries can contribute to improve the application of biowaste composting.Keywords: Resource recovery; biowastes; composting; product quality; modeling. Compostaje de biorresiduos: Tendencias de investigación y pertinencia en países en desarrolloResumen Los biorresiduos son la mayor fracción de los Residuos Sólidos Municipales-RSM en países en desarrollo, siendo el compostaje una alternativa promisoria para su gestión. La implementación del compostaje en este contexto no ha sido efectiva requiriéndose estrategias para mejorar su aplicación. Este artículo analiza tendencias investigativas del compostaje de biorresiduos y presenta una reflexión crítica al respecto. Para tal efecto, emplea elementos de vigilancia tecnológica, analizando revistas científicas especializadas (periodo 2006 a 2017) y usando herramientas bibliométricas como RefViz® y Tlab®. Las investigaciones para optimizar el proceso se han enfocado en el uso de materiales de enmienda o de soporte, estrategias para la reducción en las pérdidas de nitrógeno, desarrollo de estudios de biodegradabilidad aerobia y de modelos empíricos para predecir condiciones del proceso. La integración de estas investigaciones en el contexto de países en desarrollo puede contribuir al mejoramiento de la aplicación del compostaje de biorresiduos.Palabras clave: Aprovechamiento; biorresiduos; compostaje; calidad del producto; modelado.

“…In addition to the complexity created by the relative juxtaposition of odor sources and receptors, the characteristics of odor emissions can change during different operation times of treatment facilities (De Feo et al, 2013), which further increases the complexity of source identification. Until now, although the odor emissions from individual composting plants (Cadena et al, 2009), landfill sites (Capelli et al, 2008;Romain et al, 2008;Saral et al, 2009;Scaglia et al, 2011;Ding et al, 2012;Li et al, 2013), and transfer stations (Fang et al, 2013b) have been separately investigated, little research has been done on the interactive influence of odors from multiple sources at MSW facilities (Dorado et al, 2013).…”

An integrated approach was applied to identify the key odorants comprising emissions from different zones in two adjacent waste treatment facilities (an aerobic biological treatment plant and an anaerobic landfill site), identify their precise sources, and distinguish the interactive influences between them. Seven odor families were investigated, including alcohols, terpenes, carbonyls, aromatics, volatile fatty acids (VFAs), sulfur compounds, and ammonia. Principal components analysis, characteristic molecular ratios, and ternary diagrams were used to differentiate the interactive influence of the odor sources. Among typical biotic compounds, terpenes were found to be more suitable as odor markers for their better fingerprinting character than sulfur compounds and VFAs. Ratios of p-cymene at sampling locations related to the biological treatment plant (aerobic status) were between 0.00 and 0.25, whereas those at landfill-related sampling points (anaerobic status) were between 0.25 and 1.0. The molecular ratio of terpenes was also found to be an appropriate means to differentiate between homologous and similar odor sources such as an aerobic biological treatment plant and anaerobic landfill.Implications: The aim of this work is to identify the key odorants comprising emissions from different zones in two adjacent waste treatment facilities, identify their precise sources, and distinguish the interactive influences between them. The emission of gaseous pollutants greatly affects the living quality of nearby residents, and odor complaints are becoming a major problem. In this study we utilized various pretreatment and analytical methods to obtain integrated emission information of gaseous pollutants. The results showed terpenes were found to be more suitable as odor markers for their better fingerprinting character than sulfur compounds and VFAs.
