Abstract

Cassava is a promising bioethanol feedstock as all parts of cassava plant including its tuber, stem, leaves, along with processing waste such as peel and bagasse can be used in bioethanol production. However, bioethanol potential from the whole cassava plant is not yet summarized. This research reviewed and calculated the average bioethanol yield from each part, and calculated bioethanol potential from the whole cassava plant in Indonesia. Fresh cassava tuber, stem, leaves, peel, and dry bagasse are found to have average bioethanol yield of 180 L/ton, 155 L/ton, 75 L/ton, 160 L/ton, and 390 L/ton, respectively. If the whole cassava plant along with its processing waste is utilized for bioethanol production, cassava plants that produce a ton of cassava tuber can yield 400 L bioethanol. However, it is impractical to use all cassava plants for bioethanol production, especially in Indonesia where cassava is widely used for other utilization. Considering other utilization of cassava, from a total area harvested of 700,000 ha and cassava productivity of 22.5 tonnes/ha/year, the bioethanol potential in Indonesia is 2.9 billion L/year. Even when the tuber is used for other utilization, bioethanol from unused cassava stem, leaves, peel, and bagasse is still significant and worth considering.
