中文摘要 | 本報告係收集國內木材加工廠(製材及木質材料製造廠,編號A~編號I),在100年度,101年度或102年度之消費電量,以分析製材及木質材料製造工程的CO2排出量,進而推算其在生命週期的CO2排出量及碳足跡。結果顯示在人工乾燥、熱處理,熱壓(如高週波加熱)等製程,具有較高之耗電量與CO2排出量。原木、製材及木質材料之生命週期之CO2排出量為93.86 kg/m^3 ~1413.86 kg/m^3,其CO2儲存(固定)量為733.33 kg/m^3 ~ 1466.67 kg/m^3,而其碳足跡為-364.81 kg/m^3~ -1372.81 kg/m^3,均屬於碳儲存型材料,但纖維板為+38.76 kg/m^3除外,其屬於碳排放型材料。以進口木材為原料者,上述製材及木質材料生命週期之CO2排出量及碳足跡須增加由海外船運至台灣港口之CO2排出量。 |
英文摘要 | The main purpose of this study was to investigate the carbon dioxide emission and carbon footprint in the life cycle for wood based materials. The electric consumption of wood working factories in Taiwan from 2011 to 2013 were collected and analyzed. The experimental results were listed as follows: It was found that the higher electric consumption showed in the manufacturing processes for example kiln drying, heat treatment, hot pressing (high frequency heating) and higher carbon dioxide emission. The carbon dioxide emission of sawn lumber and wood based materials in the life cycle ranged from 93.86 kg/m^3 to 1413.86 kg/m^3. Their carbon dioxide storage fixation ranged from 733.33 kg/m^3 to 1466.67 kg/m^3. However, their carbon footprint values ranged from -364.81 kg/m^3 to -1372.81 kg/m^3 except that +38.76 kg/m^3 for fiberboard. It meant that the negative value and positive value material belonged to carbon storage type and carbon emission type respectively. If the raw materials of timbers were imported from overseas countries, the values as above-mentioned must add the carbon dioxide emission by shipping from overseas countries to Taiwan. |
