A set of experimental tests on representative oil-in-water spent emulsions have been realized based on a set of treatment screening criteria so that any oil-waste producer/holder can use them to find best pretreatment solutions preventing on-site oil waste generation and preserving in the same time depletion of non-renewable natural resources by recovery of valuable components in the context of sustainable development.en-USEmulsionsOil-in water emulsionsWaste oilsArticle10.37358/RC.20.4.8068
