Recycled copy paper

Employees may be rewarded for coming up with ideas to save the company money, either through cost saving methods or process improvement. Switching to recycled copy paper and identifying ways to make product packaging more earth-friendly are some examples. 

High levels of PCBs and PCNs have been found in Sweden in Lake Jarnsjon outside a paper mill handling recycled paper [8]. The source was suggested to be carbon-less copying paper, which previously has been shown to contain lower chlorinated PCBs. 

Two compounds are currently of particular interest in paper and board. Diisopropyl naphthalene (DIPN) is a mixture of isomers that until recently were widely used in carbonless copy papers as ink solvents. Although it is currently being replaced it occurs as a persistent contaminant in recycled paper and board. Various studies have shown that it is able to migrate from paperboard into food. There is a draft CEN analytical method available. This method involves acetone extraction and quantification by GC-MS using diethyl naphthalene as an internal standard. There is currently no limit for DIPN but levels are being monitored to reduce concentrations in recycled paperboard. 

This second edition of Pharmacotheon consists of 5000 copies, printed by Braun—Brumfield on white 60 pound book recycled, add-free paper, with sewn-and-glued bindings for permanence.
