摘要

目前本國已有許多生質能再利用的研究計畫，但仍未有實質設廠之案例，故本研究旨在落實永續發展之環保理念，進行生質廢棄物設廠再利用產能之可行性評估，以供未來設置廢棄物生質能源發電廠之用。
藉由生質廢棄物產出生質能源，具有達到資源永續利用、提供穩定能源來源、能源利用效率提升及減少溫室效應氣體產出之優點，而建置一生質能源再利用廠，需考量物料來源、種類、物料轉能效益、設廠經濟規模等因素，本研究以桃園環保科技園區為例，初步結論，依據生質廢棄物料種類、經濟效益等評估結果，該廠應為解決桃源廚餘廢棄物問題，同時具有產生替代能源、生產有機肥料、維護環境等多方效益之可行處理方案。
研究結果顯示桃園縣應以廚餘作為生質能源再利用廠之主要物料來源，而以豬糞尿及農業廢棄物作為輔助物料來源，廚餘收集範圍應以新屋鄉、大園鄉、大溪鎮及復興鄉以外之其他鄉鎮市為主，而建置規模以日處理量150公噸具有較高收益與較低之投資風險，同時生質能源再利用方案以甲烷生質氣直接出售，為降低投資風險及高回收效益之最優方案，但考量能源短缺造成價格提升與熱能再利用之因素，仍建議以發展產電供熱之方案較佳。
而除實質之經濟效益外，生質能源再利用廠同時具有提供地方居民更為優質之生活環境、提供國內優良環保教育宣導的題材及減少廢棄物處理之二次環境污染等多項非經濟之環境效益。

At present there are many domestic use of biomass longer research project, but has not yet set up a factory in real terms in the case, so this research is to implement the sustainable development of environmental philosophy, to set up a factory re-use of waste biomass production feasibility assessment to set the waste for future use of biomass energy power plants.
Born biomass waste produced by the quality of energy, with the goal of sustainable use, providing a steady source of energy, energy efficiency upgrading and the advantages of reduction of greenhouse gas output, while the build quality of life, the energy re-use plants, need to consider the source material , type, material transfer can be effective to set up factories factors such as economies of scale, this study Environmental Science and Technology Park in Taoyuan, for example, the preliminary conclusions, based on types of biomass waste materials, economic and other results of the assessment, the plant should be resolved Taoyuan kitchen waste material issue, and has produced alternative energy sources, production of organic fertilizers, maintenance and environmental benefits of a viable multi-treatment program.
The results showed that Taoyuan County should be based on kitchen waste as a biomass energy plant re-use of the main sources of materials, but with pig manure and agricultural waste as a supplementary source of materials, kitchen waste collection areas should be based on rural estates, large garden rural, large Town and Fusing Township other than the main townships, but in order to build the scale of daily processing capacity of 150 tonnes of high investment returns and lower risks, re-use of biomass energy program of bio-methane gas sold directly in order to reduce investment risk and high recovery efficiency of the optimal solution, but the consideration of energy shortages caused by price increases and heat longer use the factors, it is advisable to develop the production of electric heating program better.
In addition to the substance of the economic benefits, re-use of biomass energy plant at the same time providing local residents with a more high-quality living environment, providing excellent environmental education advocacy of domestic subjects and reduce the secondary waste disposal and environmental pollution of a number of non-economic environmental benefits.
