EcoReFibre fibreboard recycling project takes decisive step forward
in particleboard production. The demo then focused on fibreboard-to-fibreboard recycling. Using a

The EcoReFibre consortium has met at Dieffenbacher’s Eppingen base to demonstrate and discuss interim results of the research project which aims to to recycle waste fibreboards and use the material in the manuacture of new fibreboards. EcoReFibre, which
comprises 20 partners including Dieffenbacher, is backed by €12m in EU funding to develop a solution to the pressing problem of utilising waste fibreboard.
A meeting at Dieffenbacher
on April 23 was followed by a further meeting at partner Tomra in Mülheim-Kärlich on April 24.
During the demonstration at Dieffenbacher, fibreboard material was shredded to chip size in the single- shaft shredder designed by Dieffenbacher. The chips were then fed into a Dieffenbacher ClassiSizer which reduces the fiberboard material to the desired particle size. After final screening on a Dieffenbacher oscillating screen, the fines produced can be used for the surface layer
DIeffenbacher ClassiScreen, the waste wood provided by EcoReFibre project partner Veolia was separated into fines, chip-size and oversized fractions. In the same step, films, textiles and other lightweight materials such as paper were removed from the waste wood.
“In a real-life application
in a recycling plant, the oversized material would be reshredded and fed back into the process,” said Dieffenbacher Technologist Jonas Réssy. “The fines would be cleaned and used for particleboard production.” The chip-size material from the demonstration was made available to Tomra for the next day’s demonstration. In Mülheim-Kärlich, the
second day’s event focused on sorting the recycled wood by type. Using its X-TRACT X-ray sorting machine, Tomra showed how impurities such
as stones, glass, plastics and metals are detected based on their atomic density and removed from the recycled wood. This was followed by the actual sorting process. “Our intelligent GAINnext deep-learning technology reliably identifies different types of wood, for example, solid wood or fiberboard, based on shape, size or other visual characteristics,” said Jose Matas, segment director wood at Tomra.
“The result is a pure
fiberboard fraction ready for recycling.”
Dieffenbacher integrates
Tomra machines into its Dieffenbacher plant concept so that trouble-free sorting is possible on an industrial scale. Consortium leader Stergios
Adamopoulos, professor in Wood Science and Technology at the Swedish University of Agricultural Sciences in Uppsala, said the demonstration days had taken the EcoReFibre project a “decisive step forward”.
Roseburg closure of Missoula PB plant is final part of strategic plan

Roseburg is to permanently end its particleboard operations at Missoula, Montana. The company said the move
to close the particleboard plant on May 22 was the final step in the company’s strategic plan to exit the particleboard manufacturing business and focus resources
on other product segments, including MDF, engineered wood, plywood, and lumber. Roseburg acquired the Missoula plant from Louisiana- Pacific in 2003 in an expansion of the company’s composite panel business. Built in 1969, the age of the manufacturing platform created challenges as the mill competed with more modern plants. “The decision to
permanently close a plant is always difficult,” said Roseburg’s president and CEO Stuart Gray.
“It is especially difficult with our Missoula operation as we complete our exit from the particleboard marketplace. Unfortunately, Missoula’s

older platform and technology is simply not competitive from a cost structure perspective in a marketplace with many new, modern particleboard facilities.
The plant currently employs
approximately 150 team members. Roseburg will work closely with local resources to assist affected team members as the closure date approaches.
Roseburg recently announced a US$700m investment in manufacturing in Oregon, including a new plant, Dillard MDF, which will make both medium- and high-density fibreboard, and Dillard Components, which will produce exterior
trim. Construction of its Roanoke Valley Lumber mill in Weldon, North Carolina, is nearing completion, with sales of dimensional lumber
underway.members as the closure date approaches.
