Recycling newsprint is important in reducing waste. The article "The Influence of Newspaper Aging on Optical Properties of its De-inked Pulp" (M. Rahmaninia, A Latibari, et al., Turkish J Eng Env Sci, 2008:35-39) presents the results of an experiment to determine the effects of teh age of newsprint on the brightness (in percent) of the recycled paper.
