The article discusses the prospects for the development of environmental management in the disposal of livestock waste, in particular liquid manure, as part of an industrial approach to it. The data on the concentration of nutrients in liquid manure depending on its moisture are presented. Based on the analysis of empirical data and the results of previous studies, an exponential dependence is derived that indicates the relationship between the initial moisture content of liquid manure and its final volume. Criteria of effective utilization of liquid manure are formulated taking into account environmental and technological specifics.

The methodology for assessing the energy efficiency of operating actions during the separation of organic contaminants of wax has been developed. Promising methods of separation of media with complex types of bonds are proposed. The dependences characterizing the energy efficiency of separating methods for the wax raw materials have been determined. Mathematical models are obtained in the form of quadratic polynomials characterizing the influence of design parameters on energy characteristics. The influence of the design parameters of the device and the technological properties of the exposed materials in the form of wax raw materials on the values of active and reactive power has been proved. It has been established that the most rational measure for increasing the energy characteristics of devices for separating wax raw materials is to optimize their design and technological parameters.
