During the recycling of waste paper, our products united under the brand name SERFAX® are used for deinking. In order to achieve the best product performance our research and development team works on improving our existing product portfolio continuously. Of course, some waste paper is needed to run the necessary laboratory tests. For the different trials it is essential that the relation of paper, printed letters and coloured pictures stays the same to secure valid results. At this point Kölnische Rundschau helped us by giving us 40 examples of the same newspaper issue for test purposes. Afterwards Kölnische Rundschau published a newspaper article that deals with our research and development in the deinking sector. You can find the article by following the link below (only available in German language) "Diese Seife wäscht die Zeitung blütenweiß"
