Abstract

The present invention relates to a method for manufacturing a purified fiber fraction from used beverage carton (UBC), said method comprising the steps:a) subjecting a UBC starting material to a polymer and aluminum film separation method to obtain a UBC polymer and aluminum fraction and a raw UBC fiber fraction;b) optionally subjecting the raw UBC fiber fraction to a coarse screening method to remove coarse particles;c) subjecting the raw UBC fiber fraction to a fine screening method to remove cellulose fines and fine particulate contaminants, wherein the fine screening method comprises at least one fine screening step and at least one dilution step; d) optionally subjecting the fine screened UBC fiber fraction to a bleaching method;e) subjecting the fine screened, and optionally bleached, UBC fiber fraction to an electro-osmosis method to remove further contaminants;f) optionally subjecting the fine screened, and optionally bleached, UBC fiber fraction to a dewatering method to a consistency of at least 20 wt%; and g) subjecting the optionally dewatered UBC fiber fraction to a deactivation method to obtain a purified UBC fiber fraction.
