稻草文化意象與生質能發電促進環境永續發展－以雲林地區為例

本論文探討雲林地區歷年來以環境永續經營理念出發，並以舉辦稻草文化意象活動之作法對比其與稻草露天燃燒產生之環境污染現象；但由於文化意象活動對廢棄稻草之去化不足，本論文期望以生質能燃燒發電為一有效之去化路徑，故提出係數計算法估算雲林縣各種大宗農作物如稻米、玉米、高粱、大豆、花生及甘蔗之生質廢棄物產量，進而利用係數法估算其農業生質廢棄物於生命週期內，以生質能發電廠（附設廢氣處理設備）取代露天燃燒在廢棄農作物運輸、破碎及燃燒發電三階段之空氣污染物排放量，並討論建議合適做法以促進污染物減量及環境永續發展。

This study focused on Yunlin County (Taiwan), which has, in recent years, adopted environmental sustainability-oriented philosophies; hosted activities for promoting its rice straw cultural image; and discussed its practice of cultural image promotion in contrast to the environmental pollution caused by outdoor straw burning involved in such activities. However, these cultural-image-promoting activities have eliminated only part of the waste rice straw. This study thus aimed to establish an effective elimination approach through biomass-combustion-based power generation, using a coefficient calculation method to estimate the volume of biomass waste generated from major agricultural products in the county, such as rice, corns, sorghum, soybeans, peanuts, and sugarcane. The coefficient calculation method was subsequently used to estimate the volume of air pollutants emitted by agricultural biomass waste within its life cycle during the stages of transportation, grinding, and combustion in biomass power plants (equipped with waste gas treatment facilities), as a replacement of burning the waste outdoors. Finally, this study proposed recommended approaches to treating agricultural waste that facilitate pollutant reduction and sustainable environmental development.
