1. raw material used to make paper
It is made by separating only the plant fibers, decolorizing and refining them, and this is called pulp. Coniferous trees are mainly used as raw materials. Looking at the composition, cellulose is about 50%, lignin[1] About 25%, pentosan about 20%, and the remaining substances are about 5%. A series of pulp refining and mass production technologies invented in the 19th century made it possible to extract pulp from most plants, not just the most suitable woods, such as mulberry or mulberry.
95% of global paper pulp production comes from wood harvesting or recycled pulp, and the remaining 5% comes from crop by-products (straw, hemp, etc.). The most common source is sawdust or residue from sawmills, which is a by-product of sawmills (45%), 21% is made directly from logging, and 34% is made from resource recycling. The country that produces the most is the United States, which ranks first in the world with an overwhelming lead of 30%. Next is Canada, followed by Finland, Sweden, Brazil, Japan, and Russia. Korea’s pulp production is less than 0.2%.
For conifers and hardwoods 40 feet tall and 6 to 8 inches in diameter, the average number of trees needed to produce one ton of paper is 24. In cases where the strength or beauty of the paper is not important, such as newspaper or scrap paper, only 12 plants are needed.
