Joint Application of Biological Techniques for the Remediation of Waste Contaminated with Hydrocarbons

Abstract Cleaning the oil industry's fuel storage and management facilities generates high levels of hazardous waste. This research aims to assess use biological bioremediation treatments, most commonly used for decontaminating soil, by applying them hydrocarbon-contaminated Turned pile composting using food-derived sludge as a co-substrate necessary proportion bulking agent enabled initial mixture via succession microbial populations (PLFAs), with 70% lower TPH concentration obtained 6 months after start process. Subsequent bioassays composted material showed survival rates over 80% earthworms ( Eisenia andrei ) larger decrease in joint treatment plants Pennisetum clandestinum ). The process reduces organic compounds, allowing proper development fauna flora compost improving biodegradation rate. Graphical
