Increasing space limitations for disposal of solid waste and shortages of raw materials for plastic have increased the need for recycling. However, printed plastic surfaces cannot be effectively recycled unless the inks are removed. The use of surfactants for deinking rather than organic solvents or chlorine bleaches is environmentally attractive. In this study, the effect of cationic surfactant concentration, pH,
