Title (EN) METHOD AND APPARATUS FOR PROCESSING MIXED ORGANIC WASTE
(FR) PROCEDE ET APPAREIL DE TRAITEMENT DE DECHETS ORGANIQUES MELANGES
Abstract:
(EN) In order to provide a method and apparatus for processing solid mixed organic waste to produce a fuel or organic compost, the waste material is treated in a rotary aerobic digester (116), where it is digested in the thermophyllic phase at a temperature in the range 60-75'C, the oxygen content of the gas in contact with the material being treated being maintained at a level above 5% by volume, to produce a treated material having a moisture level not exceeding 45% by weight, more preferably not exceeding 35% by weight and most preferably not exceeding 25% by weight. The treated material can be subsequently dried on a drying floor (123) to provide a stable product. Waste having a high moisture level, such as domestic waste is blended in a blender (115) with waste having a lower moisture level, such as commercial waste, to provide control of the properties of the waste being treated and of the product obtained. The treated solid mixed organic waste from the aerobic digester may also be pyrolysed and, optionally, subsequently gasified.
(FR) L'invention concerne un procédé et un appareil de traitement de déchets organiques solides mélangés afin d'obtenir un combustible ou du compost organique. Selon le procédé de l'invention, les déchets sont traités dans un digesteur aérobie rotatif (116), dans lequel ils sont traités dans la phase thermophile à une température située dans la plage comprise entre 60 et 75 °C, le teneur en oxygène du gaz en contact avec le matériau traité étant maintenue à un niveau supérieur à 5 % en volume, afin d'obtenir un matériau traité présentant un niveau d'humidité ne dépassant pas 45 % en poids, de préférence ne dépassant pas 35 % en poids et ne dépassant pas idéalement 25 % en poids. Le matériau traité peut être ultérieurement séché sur une pile de séchage (123) afin d'obtenir un produit stable. Les déchets présentant un niveau d'humidité élevé, de type déchets domestiques sont mélangés dans un mélangeur (115) à des déchets présentant un niveau d'humidité inférieur, de type déchets commerciaux, de façon à réguler les propriétés des déchets en cours de traitement et du produit obtenu. Les déchets organiques solides mélangés traités en provenance du digesteur aérobie peuvent également être pyrolysés et éventuellement, ultérieurement gazéifiés.
