Purpose. To conduct a comparative economic analysis of cermet alloys regeneration technology to identify the most “environmentally friendly” and cost-effective processing of solid alloys waste. Methods. As a research technique current article considers analysis of current methods of tungsten cobalt hard alloys regeneration: pyro and hydro metallurgical, chemical (chlorine, zinc), thermochemical and using explosion energy of blasting explosives. Findings. A comparative economic analysis or cermet alloys regeneration technologies was conducted. Originality. Fundamental way of shock wave treatment to stimulate destruction of powder product of any configuration in order to obtain a high quality powder for further formation, sintering and tool manufacturing of multiple use is demonstrated; ecologically friendly technology of hard alloys and cermet components of outdated military hardware and ammunition recycling. Practical implications. Industrial mastering of the developed technology allows to solve the following issues: ? utilizing super hard metal and alloys scrap subsequent regeneration, which ensures significant savings of strategic raw material; ? the use of new technology, which excludes ineffective ways of scarce raw materials working and manufacturing products as per international standards; ? gradual reduction of import in favor of hard alloys cermet tools; ? reduction and subsequent cut down of strategic metals and alloys scrap export, shifting towards export of readymade products ? powders and tools, which will significantly increase foreign currency earnings in the country.
