Abstract

La présente invention est destinée au domaine technique de la fermentation des déchets d’origine organique et permet d’augmenter les rendements de production de méthane par fermentation anaérobie à partir de matériaux de lignocellulose d'origine végétale. L'invention concerne une nouvelle composition à base d’un polymère superabsorbant et de fer permettant d’accélérer la dégradation de ce type de déchets organiques ainsi qu’un procédé la mettant en œuvre.
