Abstract

La présente invention concerne des procédés et des systèmes pour traiter des déchets organiques. Ce procédé consiste à déterminer la température seuil d'inflammation pour un mélange constitué de déchets organiques et d'au moins un sous-produit minéral, à sélectionner un rapport de déchets organiques sur sous-produit(s) minéral/aux, sur la base de la température seuil d'inflammation déterminée, à combiner le(s) sous-produit(s) minéral/aux aux déchets organiques, de façon à obtenir un mélange présentant le rapport sélectionné de déchets organiques sur sous-produit(s) minéral/aux, puis à sécher le mélange de déchets organiques et du/des sous-produit(s) minéral/aux, afin de produire des déchets organiques solides. Les procédés de traitement selon cette invention sont des procédés pour stabiliser les déchets organiques traités, afin de commander la sensibilité à l'inflammation des déchets organiques. La présente invention concerne également des déchets organiques solides produits selon les procédés de la présente invention.
