Abstract
本計畫總目標擬對畜禽糞之再利用，規劃集中雞糞燃燒發電廠及沼氣工廠，將畜禽糞便轉變成再生電能、再生燃料 (沼氣或生質甲烷) 以及有機質肥料，並提出低碳排之區域性畜牧資源再利用方式與最佳策略。目前禽糞的處理方式多以土地利用為大宗，但因禽類的區域集中飼養特性，導致附近的土地施肥利用易達飽和狀態，因此亟思開發減碳效率更佳之再利用方式。本研究係彙整針對國內蛋雞飼養密度最高之彰化縣，及肉雞飼養密度最高之雲林縣，進行區域性畜禽糞燃燒發電之評估和經濟效益分析；研究發現，兩地區發電廠之營運設立欲具有投資可行性，都需要政府對於初始機械設備或電力收購價格，予以適當幅度之補貼。另外，在原料供給面上亦需相關法令的增訂或修改，使得雞糞原料之供給得以有條件取得或是無償取得，方具有成本降低以利投資之作用。同時，本研究亦比較國內不同蛋雞糞處理方式之溫室氣體產生量。選擇具代表性之簡易堆置法、堆置堆肥及機械翻堆之蛋雞糞處理方式進行比較，結果顯示機械翻堆的堆肥熟成度最高，所產生的溫室氣體也相對較少，但機械翻堆的過程中使用機械所產生的二氧化碳為三種堆肥方法中最多。若能降低機械的用電，必然可以減少溫室氣體產量。
The objectives of this project are focused on re-utilization technology of livestock animal manure for planning centralized poultry manure power plants and biogas plants as well as proposes optimal strategies for low carbon emission localized livestock resource re-utilization. Both power plant and biogas plant can make animal manure to electricity, renewable energy (e.g. biogas or bio-methane), and organic fertilizers. Poultry litters are mostly used in farms which centralize at some regions nowadays, therefore, developing regional re-utilization models with low carbon emission is well needed. This research integrates the results of the economic benefit scenario analysis of power generation from poultry litters combust of laying hens or broilers in Taiwan. Investment is worth only if the government subsidizes related equipment or the purchased price for electricity. Moreover, government also needs to revise the regulations about raw material supplication, to make it possible to obtain poultry litters in lower price or for free. This study also compares the greenhouse gases (GHG) emission of different manure management methods: simple fermentation (A), compost turned with bucket loader (B), and compost with automatic turner (C). Results showed that the manure form method C was well-fermented with lowest GHG emission. Although method C produces some GHG from automatic turner, method C is the prior manure management method applied if the mechanical electricity cost could be reduced.
