摘要

由於全球暖化效應（Global Warming Effect , GWE），世界開始正視其國內二氧化碳排放量，並加以調查及控管。在無法避免使用石化燃料的情況下，提高石化燃料的使用效率，並搭配二氧化碳的捕獲、封存與再利用技術，可有效減緩溫室效應的惡化。木製家具工業為木造工業之首，亦為民生不可或缺之必需工業。因此，本研究主要目的在蒐集木質家具業各項數據資料，透過計算與統計木質家具製程前後二氧化碳排放量及儲存量差異，並以二氧化碳封存技術為出發點，探尋以現今木質家具工業來達到封存二氧化碳的可行性，以提供產業界對於二氧化碳封存的另一種選擇，並導正社會誤認為採伐林木是造成森林大量減少及增加大氣二氧化碳濃度的元兇之一。
從2009年數據顯示，臺灣木質家具年產量約98.2萬公噸，使用原料為原木料122.75萬公噸，木質家具製造過程中排放之二氧化碳為88.31萬公噸，但木質家具原料（木材）儲藏之二氧化碳為206.92萬公噸，在扣除製造過程排放之二氧化碳量後，可削減大氣中二氧化碳約118.61萬公噸，證明木質家具廠對大氣二氧化碳濃度降低有其助益；另國人每回收1公斤二手木質家具可減少0.93公斤二氧化碳排放。
初步驗證木質家具工業封存二氧化碳理論是可行的，其如木材製品封存大氣之二氧化碳相同，雖然產品不同，但本質相同，皆由碳元素組成，而比較各國二氧化碳封存技術來看，其大多尚在研究階段，尚有很多難題無法克服，但木質家具製造技術可說非常成熟，並無技術上之困難，且現今可大量生產執行，雖仍有其他對環境所造成之污染尚待解決，但就應用面是可行的。數據顯示每製造1公噸木質家具及其他生活用具之二氧化碳排放強度維持在2噸CO2/噸原木以下，具有碳儲存效果。

Due to the Global Warming Effect (GWE), every country in the world began to envisage, investigate, and control its domestic carbon dioxide emission. Although fossil fuels could not be abandoned in short time, raising the efficiency and coupled with the technologies of capturing, storing, and reusing carbon dioxide, might effectively slow down the deterioration of the greenhouse effect. Wooden furniture industry has the largest proportion of wood-based industries and is an indispensable industry for our daily lives. Therefore, the main purpose of this research was to collect the data of the wooden industry and calculated the difference between the carbon dioxide emission and storage volumes before and after the wooden furniture making process. Based on the carbon dioxide storage technology, the feasibility of carbon dioxide storage by modern wooden industry was explored, and could provide the industry with another choice of carbon dioxide storage. People’s misconception that cutting trees for making wooden furniture was one of the prime culprits of the significant reduction in forest and the increase in the atmospheric concentration of carbon dioxide should be corrected.
According to the statistics, the carbon dioxide emission of Taiwan’s wooden furniture industry had been lower than the carbon dioxide storage of its required wood material since 2000. Also, the extensive use of recycled wooden furniture had further helped achieving the energy saving objective. The data of 2009 indicated that Taiwan’s annual output of wooden furniture was about 982,000 metric tons, and the materials used were 1,227,500 metric tons of original timber. The carbon dioxide emitted in the wooden furniture making process was 883,100 metric tons, but 2,069,200 metric tons of carbon dioxide were stored in the wood material. After deducting the carbon dioxide emitted in the wooden furniture making process, we could see that the atmospheric carbon dioxide was reduced by about 1,186,100 metric tons. Additionally, recycling of one kilogram of waste furniture redused 0.93 kilograms of carbon dioxide emission.
This proved that wooden furniture mills had positive effect on the reduction of atmospheric carbon dioxide. Also, we confirmed that the theory of wooden furniture making industry storing carbon dioxide was feasible that were essentially made from carbon. Carbon dioxide storage technologies are mostly in the research stage and face many difficulties, therefore still have a long way to go. Wooden furniture making was a mature technology which had less technical difficulties and could implement the mass production. It did have other pollutions to the environment, needed to be resolved, though it still was practically feasible. Data showed that the intensity of the carbon dioxide emission caused by producing a metric tons of wooden furniture could be kept under 2 metric tons of CO2 per metric ton of original timber, so that it did have carbon storage effect.
