Intensive pollution of the environment by environmentally hazardous wastes of human economic activity continues on the globe. Lubricants contribute their share in the emissions of toxic industrial waste into the atmosphere, soil and water. The article discusses the main trends in solving the problems of the production of environmentally friendly lubricants. The data on the technological processes of the production of oils based on petroleum, vegetable raw materials and synthetic oils are presented. It is shown that the currently used production processes of base oils and the base oils obtained do not fully meet modern requirements for technical and environmental parameters. It has been revealed that the most effective methods of obtaining base oils with improved environmental properties are thermal-catalytic processes, synthesis of polyester, polyalphaolefin oils and production of vegetable oils. Improvement of physical-chemical and operational properties of lubricating oils, requires adding compositions of special additives to them.
