Abstract
Leading European paper manufacturers founded the International Association of the Deinking Industry (INGEDE) in 1989. The association supports research in the field of deinking of printed papers, and it has established a database containing five optical measurements for evaluating the deinkability for the most important types of printed products. INGEDE test methods are available for the evaluation of the recyclability of printed products. In particular, the INGEDE method 11 reproduces the flotation deinking steps on the laboratory scale to evaluate the deinkability of printed products.
This research reviews the deinkability of printed papers from INGEDE institute in an attempt to adapt the European deinking protocol, INGEDE method 11, to the equipment and material available at Western Michigan University. The experiments utilized low weight coating heat samples. Five optical characteristics were determined in deinked pulp, which contribute to the final test results. Three of those, luminosity, a* color value, and equivalent black area refer to the quality of deinked pulp, the other twoink elimination and filtrate darkening are process characteristics. Test results were converted to a score system. Some simplifications were considered to adapt the INGEDE method 11 to the equipment and material available at WMU.
