摘要

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 12,954 m^3 and on average 1079.5 m^3 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.

宜蘭縣早期為國內重要林場之一，相關製材產業聚集，目前縣內仍有數十家木材加工廠持續經營，為瞭解該區域製材原料來源與木質廢料量，本研究針對宜蘭縣羅東一帶區域內之製材與木材加工廠進行問卷訪談，同時搜集國際間應用木質廢料成功發展案例進行分析，評估調查區域內之木質廢料再利用形式與效益，以提供作為未來該等資材再利用政策發展參考之用。調查結果顯示，2015年宜蘭縣羅東地區木質廢料量約有12,954 m^3，平均每月產生1079.5 m^3廢料，占木材總需求量15.4%。根據分析國外成功應用案例，以轉型製造木質燃料顆粒最具經濟效益之潛力，本研究調查所獲得木質廢料資材之數量，換算成電力度數約可達26,009,800 kWh，可提供作為區域性替補再生能源供給之用。
