Deinking Plants

The production of high quality printing papers, newsprint and tissue from recycled fiber is challenging and mills need to handle more furnish variability, as paper qualities get mixed and contaminated with non-fiber materials.


Valmet solutions – from recovered paper to deinked pulp

Valmet offers innovative deinking technologies and cost-effective subprocesses, from pulping to stock preparation for efficient impurity removal, high yield, controllable ash content and high brightness gain.

Advanced process controls from Valmet further maximizes your process performance and ensures stable quality furnish to production of high quality paper grades.

Efficient wet strength broke pulping after stock preparation rebuild

Essity’s Collodi Mill in Italy solved their stock preparation challenges by rebuilding the existing system. TM2 produces colored tissue grades and that places high requirements on stock preparation, especially in terms of capacity, energy consumption and safety. The rebuild included a new bale pulper with an innovative rotor design well suited for wet strength broke repulping, two OptiFiner deflakers, an OptiFiner Pro refiner and an under machine pulper.
