We are conducting deinkability evaluation according to the newest ISO standards (ISO 21331:2020; ISO 21892:2020; ISO 21993:2020 ) and according to the modified INGEDE 11 method .The modified INGEDE 11 method is a laboratory simulation of the most important steps of flotation deinking (defibration and flotation). It enables suitability evaluation of printed papers for removal of printing inks during industrial deinking process. Results are expressed in terms of fiber yield and ISO brightness of obtained fibers.
Deinkability evaluation is requested for acquisition of some eco-labels. Deinkability is an important feature of printed products, which are used as raw materials in paper recycling.
