摘要:	中文摘要尼加拉瓜雖然是一個農業國家，但在過去的幾年，礦業、漁業和生態旅遊產業也不斷發展；令人鼓舞的是，綠色技術專案計畫也日漸增長。屠宰產業仍是尼加拉瓜的經濟很大一部分，但環境污染的壓力促使這行業加速綠色技術的需求。本研究首先評估屠宰場對於環境的影響，然後針對較重要的環境影響衝擊項目，探討可降低污染的最佳可用技術 (BAT) ，並採用成本效益分析法探討所提出的BAT方案的可行性。根據本研究的分析與調查，屠宰場廢水對環境衝擊的最大污染源主要為牲畜的糞便和血水。尼加拉瓜全國的屠宰場每年可以產生 667.54噸的糞便和 444.64噸的血水，雖然糞便重量方面較多，然而血水對於環境衝擊的貢獻高於糞便污染，因為血水有較高的生化需氧量。本研究所提出的最佳可行技術是將糞便及血水成份經共消化程序轉化成生質燃料以供發電。由成本效益分析計算得能源均化成本(LCOE) 每度電為3.96元尼加拉瓜幣。.;Nicaragua is primarily an agricultural country, but mining, fisheries, and eco-tourism industries also have been expanding during the last few years. It is encouraging that the green technology projects today are growing at a fast rate. Slaughterhouses are still a big part of Nicaragua’s economy, but the pressure of environmental pollution has prompted the industry to accelerate demand for green technologies. The object of this study is first to estimate the impact on the environment that the slaughterhouse industry have in this nation, then determine a Best Available Technology (BAT) for slaughterhouses to reduce significant environmental impacts of the business activity. The cost-benefit analysis approach is used to determine the financial feasibility of the resulting option of the proposed BAT. From the investigation and analysis of this study, it found that manure and blood generated by the slaughterhouse into wastewater are the largest environmental concerns. The slaughterhouses in Nicaragua can generate manure with 667.54 tons per year and blood with 444.64 tons per year. However, blood actually has the biggest impact than manure on the environment because of its higher BOD production in the wastewater. The proposed best available technology in this study is to recover the soluble and biodegradable composition of manure and blood in the slaughterhouse and produce biogas for electricity generation by co-digestion method. In the cost-benefit analysis, the Levelized Cost of Energy (LCOE) of C$3.96 (Nicaraguan Cordoba currency) per kilowatt-hour was obtained.
