Fiber recycling is helping reduce fiber waste and find another alternative for it to help our environment. This special process use office wastepaper, etc. to provide and produce clean recycled pulp to create recycled content for paper and paperboards. The process starts with when paper waste is combined with water and chemicals. It is reduced to pulp mix into a large pulper. The pulp mixture is then diluted with water and goes through a process of cleaning devices and screens. The process removes any sizeable contaminants such as glass, paper clips, plastic, rocks, and wood. It also removes small impurities such as glue and other adhesive materials.
After the pulp is constrained of water and dissolved inks, it is then carried into a kneading device. Here the pulp fibers are rubbed against each other. This loosens the inks even more, while the kneading chemicals are put in to brighten the process. The brightening process helps stop the yellowing affect sometimes seen as for instance in a newspaper. After the brightening process the fibers go through a very fine screening procedure. This removes any leftover glue pieces and small debris.
During the ink removal process the pulp is merged with chemicals, called surfactants. Ink debris, glue and other tiny debris stick to the suds and float back to the surface where they are skimmed aside making the pulp even more clean. Again, the pulp is washed, pressed, kneaded. Then the pulp is set in the decolorization chest. A chemical is included to take out any colors that could possibly tint the pulp. The pulp is washed again to get rid of any left-over ink debris, or other debris. The finished fiber recycled pulp can then be sent off to a mill for paper developing or a wet lap for shipping and selling.
