本研究評估於史瓦濟蘭將農業及林業之殘料回收， 用以開發生質能源的潛勢。史瓦濟蘭年產 4.408 公噸的農業與林業殘料，經由理論計算之能源潛力 是每年1015 焦耳 (60.67 petajoule/年，PJ/y)； 於永續能源潛力 (sustainable energy potential) 方面估計，這些殘料可提供 52.3 PJ/y的能源，其中， 農業殘料貢獻 89.73%，而以甘蔗渣所占比例最高， 林業殘料為 10.27%。然而，這些頗具生質能潛力的殘料， 目前尚未為史瓦濟蘭應用現代科技予以充分利用及開發 成能源。對於此類農業與木業殘料轉換成生質能源的影響 因素，於本研究進行了討論。;This study assessed the energy potential of agriculture and forestry residue for the sustainable generation of power. The key to the methodology applied was to estimate crop and forestry residue harvesting for bioenergy while maintaining soil productivity and catering for competing residue uses. The theoretical energy potential of Swaziland estimated in this study was 60.7 petajoule per year (PJ/y) in the amount 4.408 megaton (Mt) of agricultural and forestry residues. In the estimation of sustainable energy potential, these examined residues could offer 52.3 PJ/y.The energy potential contribution of agricultural and forestry residue was 89.73% and 10.27%, respectively. Sugar cane is the most offer in energy potential of agricultural residue. However, these amount of residues currently not yet being utilized to develop maximum energy potential with modern technology in this nation. A discussion is made in this study on the factors influencing the potential conversion routes.
