Aluminium is a precious material, which when recycled maintains its surface characteristics. A 100% recyclable resource, recycled aluminum offers 95% energy savings and reduced CO2 emissions compared to the production of primary aluminum from bauxite - with consequent reduction of CO2 emissions.
Italy ranks first in Europe in the production of recycled aluminum with 70% recovery, far exceeding the objectives set by the European Union (50% by 2025).
Centro Rottami and Indinvest, a shining example of recycling from scrap into a new product
Founded in 1985, Centro Rottami of Cisterna di Latina, Italy, has been working with aluminium scrap for 10 years. Gennaro del Prete, technical director of the plant, says: "We started as a scrap iron shredder. Then five years ago we decided to specialize in aluminum refining. This specialization has been possible thanks to TOMRA's technologies."
The center processes about 1,500 tons of aluminum and 1,000 tons of ferrous scrap each month. The incoming aluminum comes mainly from old window profiles. They contain some contaminants such as plastics and rubber, as well as other metal materials like copper, brass, zinc and steel, all of which must be separated to produce pure aluminum fractions.
The company, which has been working with TOMRA for 12 years, currently has three TOMRA FINDER™ and three TOMRA X-TRACT™ sensor-based sorters. Once the incoming material is shredded and pre-sorted by both magnets and eddy current separators, the material follows two lines. The material dropped by the eddy current separator is processed by a FINDER™ unit, which recovers metals such as stainless steel. Advanced technologies such as SUPPIX® and Z-TECT enable FINDER™ to detect metal objects with ultra-precision, delivering exceptional purity levels for greater salability.
