Evaluación y propuesta de gestión del riesgo ambiental generado por los efluentes del proceso de extracción del aceite rojo de palma africana en el Cantón la Concordia, mediante la norma UNE 150008:2008

Abstract

An assessment and management proposal of environmental risk generated in the effluents for African red oil in extraction plant were carried out considering the Norm UNE 150008:2008. The strategical location of the extraction plant for taking natural resources and liquid waste in the closest receivers will probably have many potential dangers. Collecting initial information included description of every single daily process in the extraction plant and in lagoon of oxidation, and knowledge of controls in the working areas. How and why dangerous problems happened, and how they may affect vulnerable targets were discerned, as well as possible consequences in the human, ecological, and socio-economics environment whether risk scenery appeared. Experts in the theme assessed 16 risk sceneries which were hierarchized for assessment of environmental risk establishing probability and severity rates in identified dangers. The obtained results determined timely appropriate actions for acidification of mixed liquor (14,8); filtration of toxic substances (14,2); pollution gas emissions (14,9); lost storage capacity (11,2); discharge of effluent with indicators over the norm (11,5). It was concluded that the risk is moderated because it is rated from 6 to 15 established by norm. It is recommended to assess continuous environmental risk, especially when equipment, machines, or staff have been renovated considering the low and high risk levels must be treated immediately to generate a safe environment.
