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]
- Pine Trees. Pine trees are conifers and evergreens, keeping their holiday-themed pine needles all year round. They are also softwood trees with long fibers good for paper making.
- Spruce Trees. If you are not careful, you could easily mistake a spruce tree for a pine tree. These trees are also evergreens, conifers, and softwoods with needles and cones.
- Hemlock Trees. You can find hemlock trees all over the United States and in Canada. Only four species are native to North America, the rest find themselves at home in Asia.
- Fir Trees. There are fir trees and then there are true fir trees. True fir trees are what we are talking about here, not those fakers like Douglas-fir. True fir trees provide similar paper quality to spruce trees.
To make paper from trees, the raw wood must first be turned into " pulp." Wood pulp is a watery “soup" of cellulose wood fibers, lignin, water, and the chemicals used during the pulping process. Wood can be turned to pulp in a couple of different ways.
Pulp is a renewable, biodegradable raw material made from trees. As one of the most versatile materials around, uses for pulp range from the everyday (e.g. tissues, books, and baby wipes) to the more innovative, such as car filters, LCD screens, renewable fuel, and stickers.
Oct 28, 2022 · How is paper made? Most paper pulp is made from trees (mainly fast-growing, evergreen conifers), though it can also be made from bamboo, cotton, hemp, jute, and a wide range of other plant materials. Smooth papers used for magazines or packaging often have materials such as china clay added so they print with a more colorful, glossy finish.
The production of pulp and paper is a complex and vital process that begins with the sustainable harvesting of raw materials, primarily softwood and hardwood trees. These logs undergo pulping, which can be either mechanical or chemical, to break down into fibers.
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.
