    Pulp is made from wood and the sawdust from our sawmills and plywood mills. The process for both hardwood and softwood pulp is nearly identical, the main differences being the structure of the wood, and some slight differences in the amounts of chemicals used during the bleaching process.

    Pulp is a fibrous lignocellulosic material prepared by chemically, semi-chemically or mechanically producing cellulosic fibers from wood, fiber crops, waste paper, or rags. Mixed with water and other chemicals or plant-based additives, pulp is the major raw material used in papermaking and the industrial production of other paper products. [1][2]

  4. Papermaking - Pulping, Refining, Bleaching: Mechanical or groundwood pulp is made by subjecting wood to an abrading action, either by pressing the wood against a revolving grinding stone or by passing chips through a mill. The wood fibres are separated and, to a considerable degree, fragmented.

  5. Pulp and paper are made from cellulosic fibers and other plant materials. Some synthetic materials may be used to impart special qualities to the finished product. Paper is made from wood fibers, but rags, flax, cotton linters, and bagasse (sugar cane residues) are also used in some papers.

  6. Paper pulp, raw material for paper manufacture that contains vegetable, mineral, or man-made fibers. It forms a matted or felted sheet on a screen when moisture is removed. Except for certain special papers (such as asbestos paper), nearly all papers are made of cellulosic (vegetable) fibers.

  7. How is paper made? Follow the papermaking journey. This diagram details the papermaking process and illustrates the extensive use of recovered paper. New pulp, however, is an integral part of the papermaking process: recovered paper cannot be recycled indefinitely because the fibres lose their papermaking qualities.

  8. The paper pulp production process can be divided roughly into three stages: wood handling, fiber processing, and drying and packaging. 1. Wood handling. Wood is first debarked and cut into small chips for more efficient pulping. The bark of the trees is used for bioenergy production at the mill. 2. Fiber processing.
