For some time now, the paper industry has been looking for a new technology that facilitates efficient and effective sorting of mixed paper streams. This is why Pellenc ST and its R&D team developed Boreas, a system that can distinguish different sorts of paper and cardboard using a single infrared lighting unit, while at the same time identifying foreign materials (plastics and metals). In this way, the system ensures the reusability of the paper. The Boreas system from Pellec ST was launched in 2007, and since then it has been put into service at many sites inside and outside Europe.
The Boreas system can sort up to 8 metric tons of paper per hour. It is fed by a conveyor belt with a speed of 2.5 to 4.5 metres per second. For scanning and analysing the infeed paper, the system has a sensor that records measurement data at the rate of 2.3 million points per second. It can recognise objects with dimensions of 80 mm or larger, and it can eject them according to predefined criteria.
The Boreas system from Pellenc ST achieves a yield that is up to 90% higher than all competitive systems. The loss of usable material is thus kept to a minimum. This is excellent news for paper sorting centres, which can use the Boreas system to sort different types of paper and remove undesirable materials from the paper stream. It is also an attractive investment for paper mills, since it can help them select paper sorts with the right quality for their de-inking systems.
