Sorin Aurel RAȚIU, Nicolae Liviu MIHON, Miruna Diana ARMIONI

Abstract


Used oils are part of the hazardous waste category, which requires special management strategies, due to the pollutant content and the high degree of environmental impurity. They are also a by-product of significant economic value, their recycling facilitating the replacement of products extracted from fossil fuels with ecological variants of lubricants. Therefore, many recycling technologies have been created for this type of waste. The purpose of this paper is to present the different recycling methods currently used globally, to provide a study on the techniques applied, the substances used and the benefits of recycling waste engine oils.
