Abstract
L'INVENTION CONCERNE UN PROCEDE POUR LA TRANSFORMATION DE DECHETS CELLULOSIQUES ET LIGNEUX EN PRODUITS DONT LA DIGESTIBILITE ET LA MANIABILITE SONT AMELIOREES. SUIVANT LE PROCEDE, ENVIRON LA MOITIE DES DECHETS EST SOUMISE A UN TRAITEMENT D'HYDROLYSE EN MILIEU ACIDE TANDIS QUE SENSIBLEMENT L'AUTRE MOITIE EST SOUMISE A UN TRAITEMENT D'HYDROLYSE EN MILIEU BASIQUE; LES DEUX MOITIES SONT ENSUITE MELANGEES CE QUI PROVOQUE LA NEUTRALISATION RECIPROQUE DES ACIDES ET BASES PRECEDEMMENT INTRODUITS AVEC ELIMINATION D'EAU TRANSFORMEE EN VAPEUR PAR LA CHALEUR DE LA REACTION, LE PRODUIT RESULTANT EST MISE EN FORME PAR COMPRESSION. APPLICATION A LA PREPARATION DE SUBSTANCE ALIMENTAIRE POUR ANIMAUX.
