Abstract

L'invention porte sur un procédé pour la régénération et l'utilisation complètes d'ordures ménagères urbaines et de boues. Les ordures sont triées manuellement, puis transférées dans une machine à casser les sacs pour effectuer un traitement de cassage des sacs. Les ordures ayant subi un cassage des sacs sont criblées dans un rouleau et les produits de dimension insuffisante sont soumis à une séparation magnétique et un concassage pour obtenir des produits de dimension insuffisante concassés. Les produits de trop grande dimension sont séparés en substances organiques, substances inorganiques et déchets plastiques par soufflage à sec. Les substances inorganiques sont utilisées pour la préparation de matériaux de construction après séparation magnétique, tri manuel et concassage. Les déchets plastiques sont craqués à haute température pour récupérer de l'huile brute qui est raffinée pour obtenir du diesel renouvelable. Les substances organiques sont soumises à une séparation magnétique, un tri manuel et un concassage pour obtenir des substances organiques concassées. Les substances organiques concassées, les produits de dimension insuffisante et les boues sont mélangés pour obtenir un mélange de boues qui est soumis à une déshydratation, un séchage et un façonnage pour obtenir des produits de charbon. Le combustible gazeux résiduaire produit à partir du craquage de déchets plastiques à haute température est utilisé comme combustible pour le séchage du mélange de boues. Le noir de carbone résiduaire produit à partir du craquage de déchets plastiques à haute température est ajouté au mélange de boues pour obtenir des produits de charbon.
