Sensor sorting technology for efficient WEEE treatment

TOMRA Sorting sensor technology can help Spanish companies to comply with the the new Royal Decree on waste electrical and electronic equipment (WEEE). The automation of processes at recycling plants increases productivity and reduces operating costs, whilst increasing revenue from the sale of quality by-products.

At the 1st Networking Conference of the Gremi de Recuperació de Catalunya (Catalan Recovery Guild), held on November 6th in San Cugat del Vallès (Barcelona), Judit Jansana, Sales Director for Spain and Portugal at TOMRA Sorting Recycling, made a presentation to a large group of professionals from the sector. Jansana spoke of the current situation and most recent breakthroughs in materials recovery at WEEE plants, as well as the best available technologies for this purpose. The presentation was given in the context of the new Royal Decree on on waste electrical and electronic equipment, which represents the transposition into Spanish law of Directive 2012/19/EU on WEEE of the European Parliament and Council, of July 4th 2012.

After a brief presentation on the Norwegian TOMRA Group, Judit Jansana outlined the different sensor-based sorting technologies developed by the company and their different applications. She provided details of the different types of sensors used in TOMRA Sorting equipment: electromagnetic (EM) sensors, highly sensitive cameras (CRGB), X-Ray transmission (XRT), visible spectrum (VIS) sensors and near infrared (NIR) sensors. This equipment is capable of sorting the different materials with great precision, in accordance with their properties, including: conductivity and electromagnetic permeability, atomic density, colour, brightness, shape, transparency, light absorption, etc
