Title
(EN) HAZARDOUS WASTE TREATMENT
(FR) TRAITEMENT DE MATIERES DANGEREUSES
Abstract
(EN)
A method of solidifying a waste or soil composition containing at least one contaminant species which comprises adding to said composition binder and optionally water, mixing the binder into the waste or soil material to form a mixture thereof and simultaneously during formation of the mixture and/or subsequently after formation of the mixture, treating the mixture with sufficient carbon dioxide to achieve setting and subsequent hardening of said mixture so as to produce a solidified waste or soil composition.
(FR)
On décrit un procédé de solidification d'une composition à base de déchets ou de sol contenant au moins une espèce contaminante, ce procédé consistant à ajouter à cette composition un liant et éventuellement de l'eau, à mélanger le liant dans le matériau à base de déchets ou de sol, afin de former un mélange avec ceux-ci et, simultanément à la formation de ce mélange et/ou après formation de celui-ci, à traiter ledit mélange avec suffisamment de dioxyde de carbone pour que s'effectuent la prise et le durcissement ultérieur du mélange, de manière à produire une composition solidifiée de déchets ou de sol.
