The work analyses the ecological state of the environment when its contaminated with fuels and lubricants (through spills and flows), as well as the consequences that are caused by their accumulation in soil and water. As it has been shown, oil products that enter the soil and water environment can significantly pollute them. An assessment is given to the means, methods and technologies for cleaning the soil and water environment from petroleum products and their decomposition products. The feasibility of cleaning up by the method of sorption is substantiated as an effective, simple, affordable method, when at low cost sawdust of various types of trees is used as a sorbed material. The physicochemical, structural, absorbing and sorption properties of sawdust of various tree species, their advantages and effectiveness in comparison with other sorbents of plant origin, for cleaning up soil and water environment are presented. It has been revealed the ecological and economic advantages of cleaning the soil and water environment from oil products with sawdust of various tree species in comparison with other methods of cleaning.
