Topicality. Prevention and minimization of the consequences of oilspills is due to the high degree of their environmental danger. Therefore, measures and means to eliminate the consequences of accidents and prevent the ingress and spread of oil pollution in the environment are topical.The aim is to study the influence of mechanical processing of household polymer waste (HPW) on the change of their sorption properties and to obtain oil sorbents on the basis of mechanically processed HPW. The task is to determine the oil-absorbing properties of sorbents from processed HPW depending on the change of their physical properties.Methods and methodical: hygienic, physicochemical, statistical analysis. Oil absorption of sorbents was determined by the method of ASTM F: 726-12.The research results show that the value of the oil absorption of PPV at t = 21 ºC varies from 12.7 to 38.7 g / g depending on the type of polymer and the size of the particle fraction.For all polymers it was found that the bulk of petroleum products were actively sorbed in the first 3-5 minutes, a further increase in the duration of contact did not have significant changes in the amount of oil extraction by sorbents.Conclusions. The best sorption characteristics were possessed by mechanically activated fillers from processed PE + PP waste with the largest size in width and length (3.5 - 5.0) × (60-100) mm, which corresponded to the maximum values of the specific surface of polymer particles
