Data on biodegradation of total petroleum hydrocarbons using co-composting of cow manure/oily drill wastes

Oil drill cuttings are challenging wastes in oil sites especially in Khuzestan province, a major oil producing region in Iran. As co- composting is a simple and eco- friendly technique for bioremediation of oil base drill cutting, this data article designed to describe co- composting of oil base drill cutting with cow manure. The data suggest that with optimized mixture of cow manure/oily drill wastes (here, 20:1) could engender more effective treatment of the wastes (with final total petroleum hydrocarbon of 0.01 g/Kg). The data will be informative for oil drilling companies and environmental agencies for choosing it as a practical bioremediation process of soil/wastes polluted by petroleum hydrocarbons.
