Abstract

The present invention relates to a waste sludge recycling apparatus for a multilayer headbox being capable of supplying liquids onto a wire in a layered manner for forming a multilayer fiber web and including a plurality of manifolds to form corresponding layers of the multilayer fiber web in a forming section of a fiber web making machine, comprising a waste sludge recirculation means configured to be connected to at least one of the manifolds of the multilayer headbox for supplying waste sludge to be recycled to the at least one of the manifolds. Further, a waste sludge recycling method for forming a multilayer fiber web is provided, which comprises the steps of supplying liquids in a layered manner onto a wire of a forming section of a fiber web making machine via a multilayer headbox including a plurality of manifolds to form corresponding layers of the multilayer fiber web, and recirculating and supplying waste sludge to be recycled to at least one of the manifolds of the multilayer headbox.
