Sažetak
The objective of this research was to evaluate new type of alkali media for use in ink removal from recycled newspaper via flotation deinking. Hardwood (oak and beech tree) as the raw material for this new type alkali media was chosen because it is used in paper industry for obtaining virgin fibres as well. This naturally gained alkali, named Eco-alkali, was prepared by cooking fly ash collected after hardwood ignition. The aim was to minimize the environmental impact of chemicals for conventional flotation deinking by applying green chemistry approaches. Worldwide accepted method for flotation deinking, INGEDE Method 11, was done as a control method for defining deinking efficiency of new flotation deinking approaches. Lab scale flotation deinking efficiency was controlled by image analysis and spectrofotometric handsheets measurements (brightness and ERIC) before and after flotation. Obtained results implicates sccessfully usage of Eco-alkali in newspaper recycling process and possibility of process temperatures decreasing.
