Introduction

Emerging trends towards higher paper machine speeds, lower grammage of paper & board

and the growing importance of high-quality products increase the demands that the paper and

board industry places on the quality of fibrous raw materials.

Management of Paper for Recycling

The data-driven manufacturing of Industry 4.0 provides opportunities for a more efficient use of

raw materials. The management of Paper for Recycling can be improved by using big data

sources, such as CPS data from innovative measurement technologies and other secondary

sources.

The digital transformation of Industry.

Application and outlook

• Trouble shooting:

Identification of PfR quality fluctuations and their effects on process performance

and product quality

• Strategic orientation:

Prediction of PfR quality changes due to changes in future paper consumption,

collection systems etc.

• Connection with measurement devices:

Extended usage of measurement technologies in combination with simulation

models

• Optimisation of dry sorting processes:

evaluation of different sorting fractions as a basis for talor-made-quality sorting
