Material Recovering from Offset Prints on Paper with Alternative Fibers

The development of non-wood fibers has been one of strategies to ensure a sustainable fiber supply, including plantation management, reforestation and recycling. Some of alternative fibers are algae that can be used as raw material for papermaking. The Shiro Alga Carta papers made from algae in combination with Forest Stewardship Council certified fibers (FSC - fibers) were used in this research. Offset inks used in printing are vegetable-based (different amount of renewable raw materials) and mineral oil-based. The aim of this research was to contribute to the explanation of the ink/substrate interaction in printing on the detachment of ink from substrate and removal, as well as to study the recovered fiber characteristics. In our research we used the three-loops method. Generally, satisfactory characteristics of the recovered fibers were obtained in experimental conditions for all samples, as it is expected from environmentally friendly, with algae speckled paper. The research was supported by setting environmental sustainability.
