  • there are generally a separate inlet for each waste fraction to be sorted which means that the performance of the system is highly dependent on the ability and willingness of the users to correctly sort their waste. Waste items are often placed in the wrong inlet which makes the result of the waste sorting non-satisfactory.
  • Another problem is that waste items not-allowed in the system, such as medicals or industrial waste, sometimes are likewise thrown into the system. This considerably reduces the quality of the waste collected from the central collecting station.

Abstract

L'invention concerne un système (100) de récupération de déchets associé à un dispositif de récupération automatique des déchets. Dans la présente invention, un signal d'identification par radio-fréquence transmis par une étiquette d'identification par radio-fréquence (12) fixée à un déchet destiné à être introduit dans le système de récupération de déchets est lu à l'aide d'un lecteur d'identification par radio-fréquence (22) situé à proximité d'une entrée du système de récupération de déchets. Les informations d'identification associées au déchet sont extraites du signal d'identification par radio-fréquence, puis des actions de contrôle sont mises en oeuvre en fonction du déchet, sur la base des informations d'identification extraites. Les actions de contrôle peuvent servir, par exemple, à éviter que des déchets non autorisés entrent dans le système, grâce à un signal d'alarme ou à un moyen d'obstruction, et également à trier automatiquement les déchets.
