“…TKN was comprised among 1.6 % of AE and 2.5 % of GM; thus, the C/N ratio was similar for all composts, being in the range 10-13. However, all the products showed characteristics similar to those of composts elsewhere described (Barrena et al 2014;Bernal et al 2009;Saha et al 2010).…”

Compost capability of restoring or enhancing soil quality depends on several parameters, such as soil characteristics, compost carbon, nitrogen and other nutrient content, heavy metal occurrence, stability and maturity. This study investigated the possibility of relating compost stability and maturity to water-extractable organic matter (WEOM) properties and amendment effect on soil quality. Three composts from municipal sewage sludge and rice husk (AN, from anaerobic wastewater treatment plants; AE, from aerobic ones; MIX, from both anaerobic and aerobic ones) have been analysed and compared to a traditional green waste compost (GM, from green manure, solid waste and urban sewage sludge). To this aim, WEOMs were characterized through chemical analysis; furthermore, compost stability was evaluated through oxygen uptake rate calculation and maturity was estimated through germination index determination, whereas compost impact on soil fertility was studied, in a lab-scale experiment, through indicators as inorganic nitrogen release, soil microbial biomass carbon, basal respiration rate and fluorescein di-acetate hydrolysis. The obtained results indicated that WEOM characterization could be useful to investigate compost stability (which is related to protein and phenol concentrations) and maturity (related to nitrate/ammonium ratio and degree of aromaticity) and then compost impact on soil functionality. Indeed, compost stability resulted inversely related to soil microbial biomass, basal respiration rate and fluorescein di-acetate hydrolysis when the products were applied to the soil.

“…Diferentes experiencias [5,19,26,60] en plantas de compostaje de biorresiduos de países en desarrollo, resaltan la importancia de mejorar el proceso a través de la evaluación de estrategias que se ajusten mejor a cada contexto (i.e. materiales de enmienda o de soporte, aireación, tamaño de partícula), lo hagan más eficiente en términos de biodegradación y maximice el contenido de nutrientes en el producto.…”

“…Así mismo, autores como Li et al [23], Komilis [24] y Oviedo-Ocaña et al [25], resaltan que a pesar de desarrollarse numerosas investigaciones y avances en el campo del compostaje de biorresiduos, se presentan retos para mejorar la calidad del producto y ahondar en el conocimiento del proceso. Uno de los aspectos críticos en países en desarrollo está relacionado con la limitada calidad del producto generado al utilizar solo biorresiduos como sustrato, ya que generalmente no cumple con todos los estándares de calidad [5,8,26] ni satisface los requerimientos de los sistemas agroambientales en los que se emplea.…”

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.

Industrial sector in India is witnessing rapid growth since the last decade of twentieth century with reforms in economic laws and with establishment of special economic zones (SEZ). Such rapid industrial growth has also increased threat to the environment. In spite of great difficulty in its remediation in comparison with polluted air and water, soil pollution as a threat to human life is by and large ignored at national level in India due to lack of comprehensive information on the subject. Though coordinated effort on assessment of soil pollution is absent at national level, sporadic information has been generated by several researchers on various aspects of pollution affecting soil quality. This chapter analyses these information and attempts to assess the quantum of threat being faced by agroecosystem in the country. It indicates that soil resources are facing threats from deliberate use of contaminated organics, amendment materials and irrigation water or from atmospheric depositions, spillage of effluents etc. Nature pollutants varies from salts, toxic metals, metalloids, persistent organics with varying degree of toxicity and may be of both industrial and geogenic origins.
