DS Smith has successfully started up a stock preparation line and reject treatment system supplied by ANDRITZ at its mill in Porcari, Italy. The installation includes Europe’s largest FibreFlow drum pulper.
The new system forms part of DS Smith’s production process for packaging papers made from 100% recycled fibre for the fast-moving consumer goods and e-commerce sectors. Designed for a capacity of 1,650 t/d, the line is capable of processing a wide range of recovered paper grades.
“At the heart of the line is Europe’s largest FibreFlow drum pulper. The unit is also the 300th FibreFlow drum pulper delivered by Andritz worldwide,” said Alessandro Romagnolo, Project Head, DS Smith. “It enables gentle pulping combined with efficient removal of coarse contaminants, supporting stable operation and consistent fibre quality.”
The stock preparation system includes screens and low-consistency cleaners designed to maintain stock quality while supporting efficient energy consumption under varying recovered paper conditions. The reject treatment system incorporates a shredder and reject compactors for processing rejects from pulping and coarse screening.
“The successful start-up of this line is an important milestone for our Porcari mill. The project demonstrates the strong cooperation between our team and Andritz. With the new system now in operation, we are able to efficiently process a wide range of recovered paper grades and reliably produce high-quality packaging papers from 100% recycled fibre,” said Romagnolo.
