Research Abstract

Wood waste from wood industry, even that from demolished house, has been originally used for chip and fuel as a recycled raw material, but it recentry 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 was used for particleboard. The quality of the particleboard was equal to that from virgin wood chip.
(2) Recovery of wood preservatives was investigated by burning and heat degradation. This method could be useful as a tracing testing.
(3) A rapid carbonizing method for used timber was investigated. 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.
(4) Wood residu in forest was carbonized and the charcoals were spread into forest.
(5) The bio-degradation and photo-degradation of poliyurethane foam from liquefied wood is easily accelerated. This composite is recognized to be less environmental impact.
