Abstract:

The object of research is the processes of recycling non-ferrous metals in the recycling of sea-going ships. Recycling is the main direction for development of non-ferrous metallurgy. As the world experience shows, the use of secondary raw materials is more economically effective and environmentally safer than the use of primary resources. One of the most problematic places is the lack of recycling and modern environmental recycling technologies in Ukraine. In the study, the analysis method was used to study the dynamics of copper production in the world and the method of classification when considering the properties, the use of non-ferrous metals in shipbuilding, and also when identifying potential consumers of non-ferrous metals. In paper the analysis of properties of non-ferrous metals used in ship-building is carried out, their application in a ship design is shown. The analysis of enterprises of Ukraine, which are the main potential consumers of non-ferrous metals, as recyclables, is carried out. The largest non-ferrous metal processing plant in Ukraine – OJSC «Non-Ferrous Metals Processing Plant» (Bakhmut) – uses only non-ferrous scrap as its raw material. The rationale for the role of secondary scrap in the development of the production of non-ferrous metals in Ukraine is obtained. The dynamics of copper production in the world is analyzed. It is emphasized that the methodology used in Ukraine for assessing the benefits of different recycling classes is obsolete and does not allow correctly calculating the revenue and expenditure parts and assessing the risks. Due to the changes in the integrated approach in assessing the economic efficiency of the use of new technologies in production, the adoption of the state program for the recycling of sea-going ships can provide an increase in annual profits, the period of recoupment of costs, profitability, and the percentage of non-ferrous metal recycling.  Author Biographies Ludmila Pizintsali, Odessa National Maritime University, 34, Mechnikov str., Odessa, Ukraine, 65029 PhD, Associate Professor Department of Ships’ Repair
