Cassava roots in Indonesia are being used for food, feed and industrial purposes, which includes products such as chips/gaplek, flour, starch, and sweeteners such as high-fructose syrup, dextrose, maltose and sorbitol. The new utilization of cassava roots focuses on the new demand for fuel-ethanol. This paper explores the traditional uses of cassava roots in some detail, including their decline due to decreasing production of cassava, before moving to discuss use of cassava roots for fuel grade ethanol (FGE) and the extent cassava production will need to increase in Indonesia if it is to meet future demand for food, feed, traditional industries and FGE. By 2025, it is projected that a total requirement of 67.2 million tonnes of cassava root will be required, which is over three times the current level of production. The report concludes with some discussion on where the FGE industries might need to be located if they were to rely significantly on cassava roots as a fuel source, the suitability of planting windows and capital requirements for a FGE factory suitable for processing cassava roots. The paper follows a logical flow and is easy to read. A greater level of analysis is required for any significant development to occur.
