The value of Zorba – shredded non-ferrous metals originating from end-of-life vehicles or WEEE – continues to increase, as the demand for copper, nickel and brass created by modern lifestyles is on the rise. TOMRA’s sensor-based sorting technology can double the value of Zorba.

Many re-processors are limited by using only traditional processing methods, such as manual sorting or sink-float treatments for Zorba. Others are selling on the mixed material instead of directly recovering high quality fractions themselves. Because the cost of running TOMRA’s sensor-based systems is just 20 percent of that of dense media plants, and with global demand for recovered mixed metals continuing to rise, metal reprocessors and materials recovery facility operators can significantly enhance their profitability by directly recovering high quality fractions with this state-of-the-art technology.

Sensor-based sorting for metals works by combining different technologies to enable the recovery of high purity metal fractions from even the most difficult fractions in terms of composition, grain size and mix from mixed waste and metal streams. By increasing its purity and enabling operators to recover smaller fractions than previously possible, TOMRA sorting technology enables operators to maximize their returns on this increasingly valuable resource.
