Bioremediation of heavily hydrocarbon-contaminated drilling wastes by composting

Mostrar todas las versiones(2)

Oil-based drilling cuttings comprise a large and hazardous waste stream generated by oil and gas wells drilling operations. Oil-based cuttings are muddy materials with high contents of salts and hydrocarbons. Composting strategies have shown to be effective in the biodegradation of petroleum hydroca...
