More than 1,500 million ton of waste papers have been discarded without recycling. These waste papers including shoulder paper and paper box for food could not be used as the raw material for the paper products. In this study, fast pyrolysis method was chosen for production of bioenergy and chemicals from such waste papers. Fast pyrolysis was done by an analytical Py-GC/MS as well as lab-plant scale pyrolysis. 18 kind of paper were selected for this study, and Japanese cedar and Moso bamboo meal were used for comparison. The waste papers include inorganic matter, such as clay and carbonate, and these matters affected on pyrolysis behavior and pyrolysate distribution. Major products from waste paper were Furfural, acetic acid, dihydroacetone, 5-hydroxymethyl furfural, levoglucosan. Among of waste papers, pyrolysate distributions were differed reflecting the contents of cellulose. Waste paper with higher cellulose content produced levoglucosan in high yielded, and waste paper with lower cellulose content produced levoglucosan in low yield.
