Abstract

Fossil fuels are a major contributor to climate change, and as the demand for energy production increases, alternative sources (e.g., renewables) are becoming more attractive. Kerosene and conventional solid fuels, which are used to cook, have detrimental effects on people's health, the environment, and the economy. This study seeks to explore the potential of cassava ethanol as an alternative to dirty cooking fuels in Ghana. The study revealed that the prices of electricity and liquefied petroleum gas (LPG) are on the rise and this is making their adoption very low. The use of ethanol, an alternative clean cooking fuel that can be produced locally and reasonably priced, should be encouraged. Cassava was selected as the most viable crop for ethanol production because it is highly underutilized and can be grown on most Ghanaian land. The study also revealed that the Crop Research Institute-Agra (CRI-Agra) Bankye, a variety of cassava, will give an optimum ethanol yield. It has the potential to produce one litre of ethanol from about 7kg of fresh roots. Approximately 147 Ha of agricultural land may be used to produce 1 ton of cassava ethanol. Since cassava ethanol for cooking offers major potential for climate change mitigation, there should be an adoption strategy. This work serves as input for decision-making for industrializing the cassava sector.
加纳肮脏的烹饪燃料的替代品:探索木薯乙醇的潜力
化石燃料是造成气候变化的一个主要因素,随着对能源生产需求的增加,替代能源(如可再生能源)正变得越来越有吸引力。用于烹饪的煤油和传统固体燃料对人们的健康、环境和经济都有不利影响。本研究旨在探索木薯乙醇作为加纳肮脏烹饪燃料的替代品的潜力。该研究显示,电力和液化石油气(LPG)的价格正在上涨,这使得它们的采用率非常低。应鼓励使用乙醇这种可在当地生产且价格合理的清洁烹饪燃料。木薯被选为乙醇生产中最可行的作物,因为它的利用率非常低,而且可以在大多数加纳土地上种植。该研究还揭示了阿格拉作物研究所(CRI-Agra)的Bankye木薯品种将提供最佳的乙醇产量。它有可能从大约7公斤的新鲜根茎中生产一升乙醇。大约147公顷的农业用地可用于生产1吨木薯乙醇。由于用于烹饪的木薯乙醇具有减缓气候变化的巨大潜力,因此应该制定一项采用战略。这项工作为木薯部门工业化的决策提供了投入。
