The recycling of waste paper is of growing importance, both better utilization of the natural resources of wood and reduction of the amount of solid waste. Although the recycling industry is experiencing fast growth, the cost and quality of using waste paper are still incomparable with that of using virgin fibers. Therefore, to reduce the amount of dumping wastepaper into our limited landfills, both the new techniques and the fundamentals must be studied. Flotation deinking is one of the most efficient technologies for ink and contaminant removal from wastepaper. Our interests in paper recycling are focused on the flotation deinking chemistry, the fiber loss mechanism, and the ink-air bubble interaction.
Sticky control is another area of interest.
