Deinking

Procedure to remove ink from paperfibers. This process consists of detaching ink particles from paper thanks to a mechanical action and the use of soap to create bubbles. By attaching themselves to the ink particles, these bubbles float to the surface and are then collected from the cell. Due to their properties, these deinking froths can still be used as fertilizer in agriculture and sylviculture, soil conditioning or yet other uses (particle boards, embankments…)
