| Research Abstract |
Wood waste has been originally used for chip and fuel as a recycled raw material, but it recently tends to be dumped or burned as rubbish. This project aims to re-use the timber from demolished houses and used wood products effectively. Based from the results of this study, the following conclusions could be drawn :
(1) Wood chip from the timber of demolished house has been used for particleboard. The quality of the particleboard was equal to that from virgin wood chip.
(2) A rapid carbonizing method for used timber was developed. The two step carbonization could be more effective for removing nails and so on and for refining the charcoal.
(3) A variety of used timbers, such as used colomn, glulam, chip, saw dust and decay wood, were carbonized, and then their ability of absorption and wettability tend to be increased in increasing carbonizing temperature.
