| 中文摘要 | 糞尿處理中所排放的溫室氣體(包括甲烷和氧化亞氮)總量取決於處理方式及禽畜糞 便的含氮量。過去 20 年來。臺灣家禽糞尿處理方式及飼養管理方法發生了顯著變化。導致 糞尿處理過程中甲烷及氧化亞氮的排放總量也隨之顯著不同。為了準確掌握畜牧產業的碳排 放數據。並更新我國家禽糞尿處理的溫室氣體排放係數。已成為當務之急。本研究於 112 ~ 113 年度。在堆置堆肥場和機械翻堆堆肥場分別進行冷季(< 15℃)、溫季(15 ~ 25℃)及 熱季(> 25℃)期間的甲烷及氧化亞氮釋放量測定。並依據白色肉雞飼養比例計算其糞尿處 理的排放係數。結果顯示。臺灣白色肉雞在堆置堆肥過程中。甲烷及氧化亞氮的排放係數分 別為 2,531.14 ± 716.37 及 106.41 ± 41.86 mg/head/life cycle;在機械翻堆堆肥過程中。甲烷及 氧化亞氮的排放係數則分別為 47.87 及 160.98mg/head/life cycle。目前。白色肉雞糞尿的主 要處理方式仍以堆置堆肥為主。但翻堆頻率較 20 年前顯著提高。導致甲烷排放係數顯著降 低。而氧化亞氮排放係數則有所增加。比較堆置堆肥法與機械翻堆法。堆置堆肥法產生的 溫室氣體為 99.07 g CO2e/head/life cycle。機械翻堆法產生的溫室氣體相對較少。為 44.00 g CO2e/head/life cycle。本研究結果將有助於更新臺灣家禽業的溫室氣體排放數據。並提供更 具科學依據的排放係數。以支持相關政策與管理實務的應用。 |
| 英文摘要 | The total emissions of greenhouse gases (GHGs), including methane (CH₄) and nitrous oxide (N₂O), from manure management depend on the treatment methods and nitrogen content in the manure. In the past 20 years, significant changes have occurred in Taiwan's poultry manure management and husbandry practices, resulting in notable differences in CH₄ and N₂O emissions compared to the past. To accurately capture carbon emission data from the livestock sector and update the greenhouse gas emission factors for poultry manure management in Taiwan, this task has become urgent. This study, conducted during 2013-2014, measured CH₄ and N₂O emissions during the composting process in both static pile composting and mechanical turning composting sites across cold (<15°C), warm (15-25°C), and hot (> 25°C) seasons. Emission factors were calculated based on the proportion of broilers raised. Results showed that the CH₄ and N₂O emission factors from static pile composting were 2,531.14 ± 716.37 and 178.65 ± 44.56 mg/head/life cycle, respectively, while those from mechanical turning composting were 47.87 and 160.98 mg/head/life cycle, respectively. Currently, static pile composting remains the primary manure treatment method for broilers in Taiwan, but the frequency of turning has significantly increased compared to 20 years ago, leading to a substantial reduction in CH₄ emissions but a slight increase in N₂O emissions. When comparing the two composting methods, GHG emissions from static pile composting were 99.07 g CO₂e/head/life cycle, whereas mechanical turning composting produced relatively less GHG emissions at 44.00 g CO₂e/head/life cycle. These findings will help update GHG emission data for Taiwan's poultry sector and provide scientifically-based emission factors to support policy and management practices. |
