Evaluation of the emission of petroleum products during the disposal of contaminated polyethylene cans

During the maintenance of private vehicles, a stream of consumer waste is generated in the form of containers with engine oil residues. When choosing methods for handling such waste, it is necessary to have quantitative indicators of the tare weight and the volume of engine oil remaining after use. Containers contaminated with motor oils during disposal, neutralization and disposal due to the emission of oil residues create increased risks of man-made impact on environmental objects. The purpose of the study is to determine the volume of motor oil remaining after emptying under various conditions. Viscosity, temperature, runoff angle of engine oil was taken into account as changing conditions. Laboratory studies made it possible to establish that when disposing containers made of HDPE (from 1 to 30 liters), in which engine oil was placed, the waste may contain from 1.5 to 15% of oil products. The smaller the tare volume, the higher the percentage of oil product residues in relation to the tare weight. It is proposed to use K 1 indicators to assess the emission of oil products from containers during its disposal, which allows quantifying the volume of engine oil that can enter the environment during disposal or disposal.
