WOOD COMPONENTS INFORMATION

Wood is an organic material that is composed of different components, including:

  1. Cellulose: Cellulose is a complex carbohydrate that makes up the cell walls of

plants, including trees. It is the primary component of wood, accounting for about 50% of its weight.

  1. Lignin: Lignin is a complex polymer that provides structural support to the cell walls of plants, including trees. It makes up about 25% of the weight of wood.
  2. Hemicellulose: Hemicellulose is a group of complex carbohydrates that helps hold cellulose fibers together. It makes up about 25% of the weight of wood.
  3. Extractives: Extractives are organic compounds that are present in small amounts in wood. They can provide natural color, odor, and flavor to wood, but can also affect its properties and durability.
  4. Water: Wood contains varying amounts of water, depending on its moisture content. Green wood can have a moisture content of up to 200%, while air-dried wood typically has a moisture content of around 12%.
  5. Ash: Ash is the inorganic residue that remains after wood is burned. It is made up of minerals that were present in the wood.

Understanding the components of wood is important for understanding its properties and behavior, as well as for determining the best ways to use and preserve it.
