The processes of extraction and processing of oil and oil products are accompanied by negative consequences at the level of the environment in the form of accidents. They act both on the water area and on land. This article is devoted to the liquidation of emergency oil and oil products spills with the help of natural sorbents. For the analysis, three readily available materials were taken in the national economy of the Russian Federation: wool, wheat straw and sawdust. The main indicative value for the sorbent is its oil capacity (sorption capacity) the amount of absorbed oil, which depends on the degree of specific surface of the material. The higher the specific surface area, the higher the sorption capacity. To determine the oil capacity, each of the materials was placed on a flat surface and artificially contaminated with oil for one hour. During the experiment, the absorbent capacity of the sorbents was determined, which for each proved to be different. Based on the data, graphs are constructed that clearly show the applicability of a material.
