Abstract: Global warming is one of the manifestations of greenhouse gas emissions from fossil fuels consumption. To reduce the trend in transport sector, policymakers around the world are favorably supporting researchers in successful programs to replace conventional fuels with biofuels. Togolese flora has a potential for agro resources rich in convertible sugars into bioethanol. This study aims to promote the use of starch of Icacina senegalensis, for green energy production. The hydrolysis of the starches was carried out with 5.5% of H2SO4 and the hydrolysates were converted biologically into bioethanol using of Saccharomyces cerevisiae yeasts as ferment. The results show that sucrose is more alcoholic than sweet hydrolysates obtained from starches. However, taking into account the non-edibility and availability of raw materials, the tubers of Icacina senegalensis stand out as the best substrate for 1th generation bioethanol production. This results can be improve by enzymatic hydrolysis and/or enriching hydrolysates with nutritional supplements.
