A Report on Investigation on Recyclability of the Troublesome Paper Materials in Paper Recycling Process

What happens to cellulosic fibers during papermaking and recycling? A review

“…Recycled fiber supplies can contain substantial quantities of materials that are unrelated to wood (Göttsching and Stürmer 1978a;Webb 1992;Ackermann et al 2000;Venditti et al 2000;Venditti et al 2001;Stauffer et al 2001;Putz et al 2003). Many such components can be called "contaminants" relative to the intended use of the fibers (Scott 1989;Klungness 1993;Brink 1997;Watanabe and Mitsuhiro 2005;Venditti et al 2005). Deposits that occur on the wetted surfaces of papermaking equipment often can be blamed on non-cellulosic components, though the problems often involve a combination of both wood-derived and other substances (Douek et al 2003;Hubbe et al 2006).…”

“…Success of any recycling program depends, to a large extent, on the responsible actions taken by the original producer of the paper, the printer, the user, and even the care taken in collection of wastepaper. The activities of a paper recycler can be made unnecessarily ineffective by the introduction of hard-to-remove stickies, inks, waxes, and other even more problematic materials (Watanabe and Mitsuhiro 2005).…”
