Aluminium and aluminium alloys contained in waste affect human health. Acid rain leaches waste and introduces aluminium ions to rivers and ground water. Studies show a correlation between Alzheimer’s Disease and aluminium content in drinking water. Problems in disposing aluminium waste affect the construction (sheet metal, profiles), electrical (wires) and transport (construction of cars and airplanes) sectors. Technologies enabling re-melting of automobiles after they are used are an innovation in the automobile industry. However, such recycling results in considerable losses due to oxidation, which contribute to increased energy and labour costs. The author deals with a new technology based on direct conversion of metal waste into solid material, without melting.
