WHAT IS CELLULOSE?
Cellulose is a polysaccharide (similar to sugar), being the main component of the cell wall of plant fibers. Along with lignin, resins and minerals (inorganic compounds), cellulose is one of the compounds that make up the wood - about 50% (figure 1). Its molecules, grouped by lignin, form bundles of fibers that form the plant cells that make up the fibers present in the wood. (Figure 2)
The purpose of the industrial process is to extract pulp from wood, in the form of a pulp separating it from lignin, resins and minerals, which are used in the generation of electric energy by the plant itself.
