Paper Recycling

Requirements for waste paper processing


The demands on the paper industry in the coming years require a completely new understanding of quality and material availability. Changes in our demographic and economic behaviour make a new generation of sorting machines indispensable.
In order to provide our customers with the best possible support for future challenges, the REDWAVE 2i was specially developed for the upcoming requirements in the paper industry. Based on the very successful NIR / C, the REDWAVE 2i has been improved and optimised in many ways. REDWAVE continues to rely on a complete solution, so the proven combination of sorting system and innovative feeding technology can be used in the future. Furthermore, the REDWAVE 2i offers the necessary prerequisites for future developments in the area of Industry 4.0 and thus becomes a future-oriented solution for the upcoming requirements and needs of the paper industry.

REDWAVE 2i – for sorting waste paper

REDWAVE 2i is available in different working widths, which makes an upgrade easier for our long-term existing customers.

The sensors reflect the state of the art of sorting technology. REDWAVE 2i relies on "sensor fusion technology". The sorting criteria are recorded and evaluated by multiple types of sensors. This approach offers a significantly improved detection of contaminants and contributes significantly to improving the quality of the end product.

Together with REDWAVE 2i, we offer REDWAVE mate – the digital, interactive companion – for our customers that allows operators an insight into the sorting process and the status of the installed REDWAVE 2i sorting machines and helps our customers to optimise the overall performance of the sorting systems. This results in higher purity, output and thus yield. REDWAVE mate makes it possible to keep an eye on all relevant parameters and provides information in the event of deviations.
