If you wonder how recycled paper is made, it is merely through the use of a pulping machine at the factory. Large quantities of recycled paper are fed into the pulping machine and then mixed with lukewarm water to create a pulp before the ink removal process. With air injection, the ink in the paper mix will rise to the top of the foam, and a skimmer will help remove the ink from the pulp. With the passage of the pulp through rollers, to squeeze out water and generate a clean material after drying up and absorbing any chemical from the pulp. The pulp is then spread on a flat-screen until it dries into a soft, paper made of recyclable material. Materials are fed in a way that they soften the papers into the ideal thickness or plies.
