      abstract = {Ethanol imports into developing countries such as Ghana  over the past decade have been on the increase. Corn,  sugarcane and wheat are major crops that are normally used  globally to produce bioethanol. The use of cassava and  sweet potato as raw materials for ethanol production has  also been demonstrated. Cassava and sweet potato, which  grow excellently in Sub-Saharan Africa, could therefore be  used as excellent and readily available local raw material  for ethanol production to replace the seventy (70) million  litres and more of ethanol imported into Ghana in 2016 for  various uses. The search for the optimum processing  conditions to hydrolyse and ferment sugars from the  starches in cassava and sweet potato had been the major  focus of all the studies in the past. The price of ethanol  produced with cassava and sweet potato compared to the  price of ethanol produced with other feedstock in the  global market would largely determine the competitiveness  and sustainability of producing ethanol with cassava and  sweet potato. The objective of this work is to evaluate the  cost benefits of ethanol production using cassava and sweet  potato as raw materials. Sika bankye (cassava variety) and  Apomuden (sweet potato variety) were cultivated and  harvested at ten (10) months and three (3) months maturity  respectively for the study. Liquefaction, saccharification  and fermentation of the cassava and sweet potato varieties  to produce ethanol were carried out with Liquozyme SC DS,  combination of Spirizyme Fuel and Viscozyme L and Bio-Ferm  XR (Lallemand) yeast, respectively. The study indicates  that the production of ethanol with a 1:1 mixture of  cassava and sweet potato using a 10,000 litres per day  capacity ethanol distilling plant generates a net profit of  between 9% and 30% over a period of five years. The  findings indicate that ethanol production with cassava and  sweet potato is a profitable venture.},
