In the process of drilling oil or gas wells, increased friction forces of the drill string against the walls of the well, as well as in the rock-crushing tool. The use of various formulations of washing liquid using surfactants from fish production waste contributes to solving a significant part of the problems. The presence of fatty acids in fish waste, which have a significant surface-active effect, allows them to be used as plasticizing additives in concrete. As a result of the introduction of these wastes into the concrete mixture, its rheological properties are improved, as well as the strength characteristics of the hardened fine-grained fiber concrete significantly increase. The use of fish production waste in the concrete mixture will reduce the cost of concrete production, and the environmental situation will improve due to the disposal of industrial waste.
