RECYCLING TECHNOLOGIES OF ALUMINIUM ALLOYS IN ALBANIAN INDUSTRY

Abstract: The increasing rate of aluminum use and its alloys in recent decades has highlighted the problems of its relationship with the environment. Aspects of reuse or recycling, and ecology in general, have become increasingly important, conditioning the design of each product from the outset. Utilization of technological waste, on the one hand, and scrap of obsolete products, on the other hand, often requires modification of traditional production processes (of primary aluminum), and even the design of new technologies, mainly scrap recycling. Ensuring the necessary purity of the product obtained from the rewriting, at a reasonable cost and without harming the environment, remains one of the strongest challenges for these technologies. Their effectiveness, consequently, is conditioned to a large extent by the processes: preparation, collection, disassembly, cleaning, sorting, chopping and briquetting of scrap. Although seemingly simple, these processes require careful design and rigorous implementation of technical discipline. It is in these last two aspects that we think that more attention should be paid to the manufacturers and processors of aluminum alloys in our country.
