Oil palm is planted to squeeze palm oil in Malaysia,Indonesia and so on. The fats and oils found in fruits are used for soap and edible vegetable oil, which is the first rank among vegetable oils in the world.
Oil palm was brought to Malaysia in the 1900s and planted in a vast plantation. As a result, it became a production country accounting for 51% of world production, but the infulence on the environment as conpensation is very large, and it is a problem now.
Oil palm begins to bear fruit in 3 years, and palm oil can be squeezed. But the amount of fruit decreases with time, so in order to stably extract palm oil in 25-30 years oil palm must be cut and replanted.
Originally fruit and empty fruit bunches are valuable as resources, but the oil palm trunk (Oil Palm Trunk = OPT) is not strong enough to be used as a building material because of its low strength. There remains a problem with the processing method because of no use OPT after felling.
For this reason, the plantation has become a state that is full of OPT which has been cut down. Currently, Palmholz is researching how to use it.
In order to squeeze palm oil, it is necessary to plant oil palm, so it is inevitable to cut down oil palm that is not worth it. This is a problem for oil palm plantations.
The following is an example of building using OPT.
This is not an example of OPT application, but we will introduce an example of construction that uses the same technology as OPT. They can be constructed with OPT.
