Resources and recycling of secondary raw materials as basis for aluminum alloys production

Abstract

Raw materials which represent basis for 'secondary' aluminum alloys are waste and scrap of pure aluminum and its alloys, as well as waste and scrap of various materials which contain aluminum or its alloys. Hence aluminum residues are numerous and they appear on various places, there is alerting open question considering necessity of collecting, preparing and processing, i.e. returning aluminum waste into the recycling process. Aluminum recycling can be considered from different point of view: economic, ecologic, technologic, etc. Our country does not have primary manufacturing, thus question of aluminum waste recycling is very significant, and this paper presents numerous data about described problem.
