Within the Tunisian market, there are different qualities of lubricating oils (engine oil, hydraulic oil, industrial oil, etc.). During their disposal, the latter must be free of any products that could contaminate them or undermine their regeneracy (example: fuel oil, cutting oil, brake fluid and any other fluid used in garages).
Segregation must take place at the level of the recuperator (where the oil drain process occurs). In conclusion, the segregation of used oils is strongly recommended to reduce treatment costs. However, SOTULUB's work method allows for the treatment of all used oils.
