Biorremediação de cascalhos de perfuração contaminados por hidrocarbonetos de petróleo

Abstract

The concern on the environmental impacts due to waste from drilling and oil exploration activities has led to further studies in the bioremediation field. Amidst the existing biological methodologies, the objective of this article was to evaluate the feasibility of landfarming technique in the treatment of drill cutings contaminated by petroleum hydrocarbons. The literature review was carried out based on studies published in the main sources from publication of scientific papers. The article presentes, among other points, factores that influence the efficiency of the landfarming methodology, as well as the applied structure in the remediation processes. The studies showed that the technique can be applied removing up to 99% of contaminants in a sustainable way, albeit one of the process limitations is the time required for biodegradation.
