Introduction. We have tried to solve two environmentally dangerous problems at the same time - water pollution by petroleum products and the growth of polymer packaging in the share of household waste. On the one hand, oil pollution is one of the largest and most dangerous types of human impact on the environment. In oil-contaminated reservoirs, depending on the concentration of hydrocarbons in the water, adult fish, caviar, larvae and young fish die on the surface of the water and in shallow water. Zooplankton in a polluted reservoir dies completely. It is established that only 1 g of oil kills all living things in 1 m3 of water. It is known that polymer waste can absorb a small amount of petroleum products (from 1.4 to 1.6 g / g) depending on the type of polymer. To increase the oil content of the polymer, in addition to increasing its specific surface area (eg, fiber cutting), surfactants (surfactants) are applied to the surface, which improve the adhesion of the polymer to the petroleum product and, thus, increase the sorption of the polymer. Mechanical treatment of the polymer surface does not have a negative environmental impact on the environment, unlike surfactants, which actively pass from the polymer surface into moist soil and water and cause pollution. However, the refusal to apply surfactants on the polymer surface makes polymer sorbents inefficient, economically and environmentally impractical due to the need to use them in large quantities. In addition, after their use, a new problem arises - highly toxic waste that needs to be disposed of. In our opinion, one of the options for solving this problem is the use of surfactants from vegetable raw materials.
