Waste oils are all mineral or synthetic oils that cannot be used for the purpose for which they were originally produced. These are: hydraulic oils, motor oils, ship oils, liquids for the transfer of heat or insulation, oily remains from reservoirs, oil-water emulsions and various oil-water mixtures. In its chemical makeup used motor oil contains hydrocarbons, organic minerals, heavy metals (cobalt, magnesium, iron, zinc), sulfur, chlorine, nitrogen, phosphorus, compounds from additives and other products that are dangerous as they have cancerous effects on health. As it is considered the biggest contaminant of the environment and classified as hazardous waste; special attention must be given in the handling of used motor oil to ensure its appropriate disposal. Setting up of a viable system for Mechanical-Physical Treatment of used motor oil makes it possible to re-use it as a secondary raw material i.e. the problem of collection, transportation, treatment and storing of the used motor oil is being solved. . The subject of this research is the advantage of the mechanical-physical treatment of used motor oil. Re- refined motor oil can be used for multiple purposes such as a base for the other synthetic oils, for heating etc. Improper disposal of used motor oil causes multiple damage; firstly, losing the valuable secondary base which, with the addition of certain additives, can be used as the basis for the other synthetic oils; secondly, causing damage to the environment by the pollution with inability to repair the damage to all environmental components.
