    Objective:

    L’industrialisation des pays en voie de développement engendre l’augmentation des déchets liquides que sont les huiles de vidange, tout en se heurtant au problème de déficit énergétique. D’autre part, elle s’accompagne d’une forte croissance démographique qui accentue et augmente la quantité de déchets, particulièrement les déchets ménagers solides. Ce qui constitue une réelle menace pour l’environnement et les populations.
