EDS FAQ
What types of timber are suited for the EDS technique? |
| All of the world’s timber is suited for the
technique. The technique is extremely effective with trees which have not been
targeted fdor secondary purposes much until now, such as the oil palm, the
coconaut palm, and with representative plantation trees such as Acaca mangium,
falcataria, and the rubber tree.
|
Oil palm, coconut palm Palm
plantations have been rapidly spreading due to characteristics of palm
oil which make it superior to other plant oils for both food and non-food
use. After about 25 years, a palm tree’s seed yield begins to fall and
it is felled. |
 |
Acacia mangium
Adaptable and fast-growing, this tree has been planted around the world mainly for use as a
basic ingredient in making paper. However, because it is prone to problems such
as warpage, cracking, and bending, it has rarely been used as a building
material. |
 |
Albizia falcataria
A fast-growing hardwood tree of Southeast Asia planted mainly for lumber. It is not fully utilized because of problems such as warpage, cracking, bending, and its low durability.
|
 |
Rubber tree
The rubber tree’s sap is used a basic ingredient in rubber products. After about 20 years, the tree’s rubber yield begins to fall and it is felled. Part of the tree’s is used as laminated wood, but ths usage rate is less than 20 %.
|
 |
Bamboo
Extremely fast-growing; found in every part of the world. In Japan, the of bamboo groves as a result of the devastation of community forests has become a problem. Bamboo is rich in sugar and carbohydrades, which makes it prone to rotting and infestation by insects. It is therefore not fully utilized.
|
 |
| If an oil palm is being felled, it decomposes until only fibers remain. However, the EDS technique improves durability and strength, making it possible for the tree to be used in fields where it was not utilized previously. (oil palm)

It is expected that a lower occurrence of defects such as warpage, cracking, bending, and low durability will lead will lead to the tree becoming more popular as a wood and as a standard building material. Moreover, when the technique is used, more portions of the rubber tree become usable, resulting in improvements to the yield ratio and enabling the effective utilization of forestry resources. (rubber tree) |
The EDS technique improves all of bamboo’s defects. Particularly noticeable are improvements to the bamboo’s strength and a favorable enhancement of its colors, both of which expand its range of uses. (bamboo)
