Abstract

L'invention concerne un procédé utilisé pour produire des matières fibreuses à partir de matières premières lignocellulosiques avec des solutions aqueuses de sels sulfuriques. Ledit procédé se caractérise en ce qu'il est prévu d'utiliser, pour produire la solution aqueuse de sels sulfuriques, le produit de filtrage et le soufre et/ou des composés du soufre résultant du traitement anérobie d'eaux usées.
