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 for secondary purposes much until now, with representative plantation trees such as Acacia mangium, falcataria, and the rubber tree.

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.
　　
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)
