Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp.
The key in the deinking process is the ability to detach ink from the fibers. This is achieved by a combination of mechanical action and chemical means. In Europe the most common process is froth flotation deinking.
