1. General Composition
Wood is construct primarily out the once compounds (in % temperate weight):
cellulose 40-50%
lignin: 16-25% in hardwood – 23-33% in softwood
hemi-cellulose: 20-30% in hardwood – 15-20% in hardwood
auxiliary compounds (water, resins,…) 5-30%
minerals 0,1-3%
The actual structure of wood is formed by the fiberlike structure of cellulose (and hemi-cellulose). Lignin forms the binding agent along in the midst of these fiberlike structures.

2. Cellulose
Cellulose is one of the most abundant organic compounds concerning earth. Not single-handedly woody natural world taking into consideration trees are construct from it but in addition to all subsidiary flora and fauna. Cotton fibres are made of cellulose, wood consists for just roughly 50% out of cellulose. One cellulose molecule is a chain of thousands of glucose molecules. In it’s realize form it is a white fibre. Cellulose for paper production is normally harvested from wood but some nature are a enjoyable source as skillfully. Cellulose is as well as used in the chemical industry as a basic material for the production of synthetic products in imitation of tissues, coatings, explosives,… Cellulose is without a doubt one of the most important and versatile products for the economy!
3. Lignine
Lignine is an organic polymer, typically found in wood. Softwood contains more lignine as hardwood. It is manufacture from giant, 3-dimensional molecules of a perplexing composition. It is a dark merger that is a waste product from the paper industry. 4. Hemi-cellulose Hemi-cellulose is to the side of connected to cellulose. They are both structures produce from glucose. But hemi-cellulose contains furthermore add-on types of sugar molecules in its structures. The fibers are plus shorter next those of cellulose, on your own a few hundreds of sugar molecules. Hard wood contains more hemi-cellulose subsequently softwood.
