Comparative life-cycle assessment of traditional and emerging oily sludge treatment approaches

This study presents a comparative life cycle assessment (LCA) of traditional and emerging treatment approaches for hazardous refinery oily sludge handling. Two traditional oily sludge disposal approaches, including incineration and landfilling, and two emerging energy recovery approaches, including solvent extraction and pyrolysis, were investigated. Life cycle inventories listing all energy and material flows were established for the two...
