EDS FAQ
How does the EDS technique alter the wood’s composition?

  1. How does the EDS technique alter the wood’s composition?
  2. When heat is applied to raw materials within the sealed plant, the moisture vaporizes. Components such as hemicellulose and lignin break down and the wood’s molecular weight decreases.
  3. When the temperature within the plant is gradually decreased, the components blend and harden. At the end of process, the quality of the raw material (the wood) is dramatically enhanced.
Images of the change in the wood’s composition

Heat and smoke travels from the combustion chamber through the heat quantity control room and into the raw materials storage room.

Moisture in the wood vaporizes, and the heat and smoke from the combustion chamber causes the wood’s composition to alter.

  Glossary
Cellulose Comprises around 50% of the wood. A relatively stable substance made of straight chains of glucose.
Hemicellulose Comprises approximately 20〜30% of the wood. A different type of sugar than cellulose. Because its binding structure is not as orderly as that of cellulose, the substance breaks down easily by hydrolysis.
Lignin

Comprises approximately 20〜30% of the wood. This macromolecule is irregular in form and includes benzene rings.
