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.

木材工业产生的木材废料，即使是来自拆迁房屋的木材废料，最初也是作为回收原料用于制造芯片和燃料，但它往往被当作垃圾倾倒或焚烧。该项目旨在有效地再利用拆除房屋的木材和使用过的木制品。根据本研究的结果，可以得出以下结论：(1)从拆除房屋的木材中提取的木屑用于刨花板。通过燃烧和热解的方法对木材防腐剂的回收进行了研究。研究了废旧木材的快速碳化方法。对各种废旧木材如木柱、胶合板、木屑、锯末和腐木进行碳化处理，随着碳化温度的升高，其吸附能力和润湿能力有增加的趋势。(4)森林中的木材残渣被碳化，木炭扩散到森林中。(5)液化木材中的聚氨基甲酸酯泡沫塑料的生物降解和光降解容易加速。这种复合材料被认为对环境的影响较小。
