Abstract

La présente invention concerne un procédé de conditionnement ou de déshydratation de boues issues de l'industrie papetière ou de boues issues de l'industrie agro-alimentaire, ces boues contenant des boues de nature biologique, dans lequel on met en oeuvre une composition obtenue par mélange d'une émulsion inverse contenant un polyélectrolyte cationique avec une émulsion inverse ou une solution aqueuse contenant un cation minéral de charge supérieure ou égale à 2.
