The analysis of the world market for recycling waste and scrap of aluminum alloys is presented. It is predicted that by 2040. the share of secondary aluminum alloys will reach almost 80% of aluminum production in the world. It is shown that for the period from 2001 to 2019. world export of aluminum scrap increased 2.7 times in quantitative terms and 3.6 times in value terms. Leaders in the global export market for aluminum scrap in 2019 are the USA (share 18.5%) and Germany (10.4%). For the period from 2015 to 2019. the most dynamic exporters of aluminum scrap are Japan (up 1.9 times), Mexico (1.7 times), Belgium (1.3 times) and the USA (1.2 times). The largest importers of aluminum scrap in the world in 2019 were China (13.7% share) and India (13.4%). The analysis of the structure of waste and scrap of aluminum in Ukraine for 2018 is presented. Based on the commodity structure of the formation of aluminum waste and scrap, the world has developed appropriate technologies and equipment. The developed and used technologies for processing non-metallic aluminum waste (slag, dross), both in salt and salt-free versions, are considered. Information on technologies and designs of furnaces for processing aluminum scrap is also provided. The positive and negative indicators of their operation are shown. The prospects of using inclined rotary furnace for large-scale processing of aluminum scrap are noted. Attention is drawn to the need to train specialists in Ukraine in the field of processing scrap metal and waste.
