Innovation in recycling –
from residual waste to hydro turbines 

Mayer Entsorgung’s (Waste Management) Styrian technology combined with plant manufacturing specialist BT-Wolfgang Binder’s REDWAVE sorting technology is behind the transformation of discarded coat hangers into high quality secondary raw material. Materials such as copper and aluminium, which were previously considered unsortable alloys, can be separated by X-ray fluorescence (XRF) technology into high-quality secondary raw materials and processed into hydroelectric turbines.
A world first from Styria
The world´s first “REDWAVE XRF sorter” is integrated into Mayer Entsorgung’s new plant, which provides maximum purity and accuracy in the sorting of non-ferrous metals. Up until now, only glass or minerals could be separated using XRF technology, but now non-ferrous metals can also be separated from each other by an innovative new development. The individual metals function as separate small transmitting stations that emit a unique energy signature and are analysed by sensors. The most important non-ferrous metal in this application is aluminium.
A new dimension of purity
For the first time ever, the new process is able to recover pure primary aluminium alloys, achieving an increase of blending in the production of aluminium, from 10% to 30-40%. “The new technology increases the value of sorted metal groups. Now we can produce high quality products, such as radiators or aircraft engines from scrap”, states Andreas Säumel, Managing Director of Mayer Entsorgung.
Up to 3,000 tons are now high-grade recycled
The XRF sorting machine of the world market leader in this segment, REDWAVE, evaluates materials using X-ray fluorescence analysis ( XRF). This physical analysis method is used in the metalworking industry, as well as in the testing of glass, ceramics and lubricants (amongst others). Until now, non-ferrous metals were separated using sink-swim-plants and X-ray transmission systems, but could not sort metals at such high grades. Now it targets the variety of materials it receives and sorts and produces highly purified metal content, unaffected by moisture, colour or impurities. The capacity of Mayer Entsorgung’s new sorting plant is 1,000-3,000 tonnes per year.
Strong Styrian cooperation of the pioneers
The new plant is the result of Anton Mayer Ges.m.b.H and BT-Wolfgang Binder’s joint research project, supported by Eco World Styria environmental technology cluster. “The new sorting plant is another example of the outstanding competence of the domestic environmental technology industry,” states regional Minister of Economy Christian Buchmann.
