  • The Papermaking Process

    Waste wood chips sourced primarily from local sawmills are processed in the new Thermo-Mechanical Pulping (TMP) System to produce up to 390 tons of pulp per day. The new TMP system significantly reduced Inland Empire Paper Company's (IEP's) dependence on natural gas to dry its paper products. Through a heat recovery system, the reduction in natural gas usage eliminated associated air emissions by more than 75%. This TMP system replaced pulping systems installed in the 1960's.

    Recycled newspapers are purchased throughout the western United States to supply our ONP deink plant. Up to 350 tons of recycled fiber cam be processed each day. Recycled pulp is blended with mechanical pulp prior to brightening at ratios from 10-60%, depending on grade requirements.

    The blended, brightened pulp is mixed with water to lower its consistency to 1 percent solids, then introduced to the paper machine through a precision nozzle called a headbox. A Voith TQv former is used to extract 85% of the water and form the sheet of paper. Additional water is removed in the press section and dryers to produce paper with an 8 percent final moisture content. Two soft-nip calenders finish the paper to the required thickness and smoothness prior to reeling into 24-ton jumbo rolls. These rolls are then cut and rewound on a winder to provide finished rolls with the required width and diameter. The rolls are wrapped and labeled, then shipped, either by truck or rail, to their final destinations.

    The latest state-of-the-art equipment and technology is installed in our mill to produce the highest quality groundwood papers available.
