Recovery of glass from the inert fraction refused by MBT plants in a pilot plant

A Survey of the State of the Art in Sensor-Based Sorting Technology and Research

“…However, sensor-based process monitoring can also provide valuable insights into material flows early in the preparation [56], [57]. Occasionally, sensor-based sorting is also applied early, i.e., on heterogeneous stock streams, for example, to selectively extract glass [58] or to remove impurities for further processing as refuse-derived fuel, e.g., polyvinyl chloride (PVC) [59].…”

Motion-based visual inspection of optically indiscernible defects on the example of hazelnuts

“…In many cases, sensor-based sorting systems can be employed for the inspection and physical cleaning of products by means of removing low-quality and foreign, potentially harmful, entities from a given product stream. The main fields of application of sensor-based sorting are recycling, for instance the preparation of glass [9] by removing materials harmful to the melting process such as stones and ceramic glass [10], mining, mainly to remove unwanted gangue from ore, e.g., copper-gold ore [11], as well as agricultural products and foodstuff. Regarding the latter, examples of applications are diverse, including the removal of fungusinfected wheat kernels [12], low-quality rice grains [13], and sunflower seeds [14], or quality insurance in bulgur The turquoise objects represent particles to be accepted, typically the product, and the red ones those to be removed, for instance foreign particles.…”

“…De glas-recyclingbedrijven hebben gescheiden ingezameld verpakkingsglas en soms ook vlakglas en autoglas als grondstof en maken daarvan meerdere glas-scherven-producten voor de glasovens van verpakkingsglas, een aantal bijproducten voor polijstmiddel-en isolatiemiddelproducenten, bijproducten voor de bouw, metaalproducten en een aantal afvalstromen.
