Beschreibung
Zusammenfassung:	A system and method of forming a molded pulp product that involves separately collecting, from a paper-making process, waste water containing short fibers at a first fiber consistency, waste water as dilution water containing fibers at a second fiber consistency that is lower than the first fiber consistency, and water containing long fibers, the long fibers having a length that is greater than a length of the short fibers, blending the waste water containing short fibers and the water containing long fibers to obtain a pulp slurry, and molding the pulp slurry into a molded pulp product at a pulp molding machine. In an embodiment, filtrate removed during the molding of the molded pulp product has a BOD measurement that is 95% less than a BOD measurement of the pulp slurry, where the BOD measurements are obtained using the EPA 405.1, SM5210B Test Method.
