The results of a study of the chemical composition of copper-containing metal waste and electroerosion powder are presented. Using a portable Niton Goldd spectrometer, it was found that copper-containing metal waste corresponds to the brand of the BrKN1-3 alloy. The data obtained made it possible to identify samples of the studied metal waste to be processed by the method of electroerosive dispersion into spherical powders suitable for additive manufacturing. As a result of comparing the percentage of chemical elements of the investigated metal waste of the BrKN1-3 alloy and the powder obtained by the method of electroerosive dispersion, minor discrepancies were found associated with an increase in the percentage of elements such as Pb, Zn, Fe, Sn in the powder, as well as with a decrease in elements such as Cu and Zr. Renovation of metal waste, including copper-containing metal waste, will contribute to resource conservation, import substitution and ensuring the technological sovereignty of the Russian Federation.
