Title (EN) TREATMENT OF HAZARDOUS WASTE MATERIAL
(FR) TRAITEMENT DE DECHETS DANGEREUX
Abstract:
(EN) Hazardous waste material is stabilized and rendered non-hazardous by mixing the waste with an alcohol component, and a surfactant component, and then binding such mixture in a cementitious matrix.
(FR) Des déchets dangereux sont stabilisés et rendus inoffensifs en mélangeant ces déchets avec un composant alcoolique et un composant tensio-actif, puis en liant ce mélange dans une matrice cémenteuse.
