On September 24, 2023, the joint-stock company “Karazhanbasmunai” organized a purity campaign as part of an eco challenge sent by the volunteers of NC “KazMunayGas”. More than 40 students and teachers of the Faculty of Engineering of Yessenov University took part in the action. Cleaning was carried out in the recreation area on the 43rd kilometer of the Caspian Sea coast. The participants of the subbotnik collected more than 100 bags of solid household waste, loaded it into a truck with the help of special equipment and sent it to landfills.
