TL;DR: The origin, characteristics, and environmental impacts of oily sludge were introduced and no single specific process can be considered as a panacea since each method is associated with different advantages and limitations.

TL;DR: The combination of solvent extraction with freeze/thaw is effective for high-moisture oily hazardous waste treatment and the solid residue after oil recovery had a significantly decreased TPH content, indicating that this residue may require proper management.

TL;DR: This review prioritizes some commonly occurring unregulated DBPs groups and species in DWDSs based on their concentration level, reported frequency, and toxicity using an indexing method to help water regulators to identify the most critical UR-DBPs species in the context of drinking water safety and provide them with useful information to develop guidelines or threshold limits.

TL;DR: In this article, a comparative life cycle assessment (LCA) of traditional and emerging treatment approaches for hazardous refinery oily sludge handling is presented, and two emerging energy recovery approaches, including solvent extraction and pyrolysis, are investigated.

TL;DR: The higher heating value of oil originated from sawdust during co-pyrolysis at a sawdust/oily sludge ratio of 3:1 increased by 5 MJ/kg as compared to that during sawdust pyrolytic alone, indicating a synergistic effect of co- pyrolynsis.
