In Oslo, NG Group had a clear ambition: to make recycled paper competitive with virgin raw materials.
To achieve this, they decided to invest in a new paper sorting line that was designed around three practical goals:
β
Increase automation.
β
Increase operational flexibility.
β
Maintain and improve output quality.
Azortum's role was system integration.
We engineered the overall layout, conveyors, structures, bunkers, material flow, and integration of specialist equipment. This meant bringing optical sorting, robotic sorting, feeding systems, and quality-control technology together into a single working production line.
The result is an automated paper sorting line capable of processing 20 tonnes per hour and up to 120,000 tonnes per year.
For Norsk Gjenvinning, the most important outcome is not only capacity, but the ability to produce high-quality secondary raw material with 97.5% de-ink fiber purity and less than 3% residue.
The fully automatic line also proved to be adaptable. This supported a later retrofit adding Tetra Pak recovery, showing how a well-integrated system can evolve with changing material streams and customer needs.
The result is a high-capacity paper-sorting line that provides NG Group with the flexibility, quality, and yield needed to produce secondary raw materials for industrial markets.
