探究室內裝修廢棄物逆物流之碳足跡
Carbon Footprint of The Reverse Logistic of Disposing Wastes of Upholstery Industry
摘要
在經濟發展變遷、人類過度使用自然資源下，導致生態環境的破壞日漸加劇，進而使環保意識以及生態保育的觀念興起，綠色議題也逐漸受到關注。逆物流，是綠色供應鏈管理主要的實現方式，其涵蓋範圍由原物料退貨、製造過程中的半成品退回，或產品銷售後退回等，到資源回收、再製造及包裝重新使用。依世界經濟合作與發展組織(OECD) 於2003年的「永續環境建築：挑戰與政策」報告中指出，全球建築物消耗了32%的資源、12%的水以及40%的能源；全球廢棄物中建築廢棄物佔40%，對環境造成極大迫害;若能有效控管建築廢棄物，對減緩全球暖化應更有助益。在建築產業中對於逆物流的落實程度並不高，因此本文以建築產業中的一環-室內裝修作為研究標的，探討企業在逆物流程序中對環境產生的衝擊。評估環境衝擊的方式之一為碳足跡量化，透過逆物流程序找尋產品生命週期中的碳排放因子並加以量化，可幫助企業檢視其產品生命週期找尋減碳機會。綜上所述，本研究以Benjaafar et al. (2013)、Pishvaee et al. (2009)與Tascione et al. (2014)的研究模型作為參考依據並發展出本研究模型。為完成模型建立，本研究將與室內裝修業者訪談了解其逆物流程序並推估碳排放因子，並由訪談收集數據導入本研究發展模型中驗證模型可適度，最後由個案差異進行分析比較以釐清室內裝修廢棄物逆物流供應鏈上的排碳問題。本研究成果發現當廢棄物進入逆物流程序對於減緩環境衝擊有明顯效果，可有效降低碳排放；當再利用機構間數增加且可處理廢棄物總量增加時的碳排放總量逐漸遞減。而此研究結果可提供企業與政府即時提出因應措施，作為減碳政策之依據。

Owing to the rising awareness of the need to protect the environment, reverse logistics is being promoted to improve ecological sustainability of production. Retuned of the materials, semi-finished products during the manufacturing process, sales and recycled, remanufactured, reused of package all included in reverse logistics. According to the World Organization for Economic Co-operation and Development (OECD) report of 2003, buildings consume 32% of resources, 12% of water and 40% of energy worldwide, and the building waste comprises almost 40% of the all waste in the world. Therefore, controlling waste from the buildings sector may help slow global warming. Upholstery company belonged to the building industry. An upholstery company generates a lot of waste in the beginning of a new interior decoration because it needs to destroy the existing decoration. However, the reverse logistics of the upholstery sector are still unclear. Through quantify the carbon footprints, enterprise can find out the carbon emission factors from product lifecycle in reverse logistics. Carbon footprints quantification helps enterprise to seek the carbon reduction chance from product lifecycle. This study models the carbon footprints of disposing upholstery waste based on studies from Benjaafar et al. (2013), Pishvaee et al. (2009) and Tascione et al. (2014). In order to model this model, this study interviewed upholstery companies to understand the reverse logistics process and the factors of carbon emissions. This study verify the model from interview data and find out the most factor of carbon emission. Result of this study discovers that the waste entering reverse logistics process significantly decrease the impact of environment. The waste recycling agencies increase, the total carbon footprints gradual decline. Therefore, the total carbon emissions changed by houses of waste recycling agency. Companies can control carbon emission through the findings of this study, and find how to improve their recycling process through reverse logistics.
