| Résumé : |
The aims of this study were to provide a business plan for implementing a bioethanol production
company, and to determine the utilization of organic wastes: fruit and vegetable wastes (FVW) combination towards bioethanol production with the used of indigenous yeasts as starter. Berries, banana, watermelon, apple, potato, carrot, beetroots and sugar beet wastes were taken as materials from Central market around Saida City. Saccharomyces cerevisiae was the indigenous yeast used in the production process, which was isolated from fermented raisins. The FVW were subjected to a pretreatment process that comprises grinding feedstock while simultaneously adding 500ml of water to create a homogenous mixture. Fermentation was conducted at a temperature of 35°C for a duration of 15 days, in an environment with a pH of 6.8. From the results obtained during the study, conclusions drawn were, maximum quantity of fermented broth (undistilled ethanol) produced was 3 litres after fermentation duration of 15 days. The maximum quantity of distilled ethanol after final distillation was found to be 450ml. These findings show/prove that ethanol can be made from the named organic waste and the process is recommended as a means of generating wealth from waste. |
