Each year, there is an increasing amount of wooden material left behind from the renovation or dismantlement of timber structures. A large portion of these wooden materials becomes waste, rather than being recycled, thereby damaging the local and global environment and creating a serious community issues. In order to sustain the timber structure construction business into the next century, including the construction of wooden houses, broad-ranging recycling technologies to reuse and recycle the dismantled materials that appear throughout the lifecycle of buildings should be developed above and beyond the construction industry. In this research project technologies to reuse and recycle the wooden construction waste as construction materials were developed. The target of this research project is to reduce the waste materials radically by establishing broad-range and advanced recycling technologies for timber structures.
