Description:Xerographic waste paper (paper derived from laser printers and photocopying machines) is difficult to deink. Consequently, paper recycling mills rarely utilize it. It constitutes 24% by weight and 40% by volume of all domestic and industrial waste in the United States.
Toner used for laser printing and photocopying is composed of carbon black and resins, which are cross-linked thermoplastic polymers. Under heat, they fuse into paper rendering deinking difficult. Research has focused on developing chemical formulations that can dissolve toner and designing better repulping plants.
This project aims at developing such formulations as well as a machine to recycle office waste paper in offices, the OFFICE PAPER DECOPIER (OPD). The basic operations of wetting, de-inking, and drying the paper to re-copying quality have been demonstrated. Phase I will improve and quantify these operations and advance the OPD design for economic projections.
