Yilan County, one of the crucial domestic logging districts in early years, contained many businesses related to the lumber industry. Dozens of wood processing plants still continue to operate in this region. In order to understand sources of lumber raw materials and quantity of woody wastes, this study focused on lumber manufacturers and wood processing plants to conduct questionnaires by interview in Luodong Township, Yilan County. Meanwhile, this study not only analyzed international research which applies to woody wastes, but also evaluated the types of woody waste recycling and benefits in this region, providing a reference for developing woody reuse policies in the future. Results indicated that the amount of woody wastes was about 12,954m3 and on average 1079.5 m3 per month, which accounted for 15.4% of the total timber demand.According to the foreign cases analyzed, it is more economically effective for woody wastes to be
converted into wood pellets as fuel than other treatments. This study also estimated that the quantity of woody wastes generated could produce 26,009,800 kWh of electric power, which could be a regional energy supply in an area that lacks renewable energy.
