The illustration presents an overview of the key stages involved in the production of ethanol fuel from corn in three main steps namely preparation, processing and delivering. The whole process of ethanol fuel manufacturing starts when corn is harvested and then put in a suitable place to ensure safe storage before entering a milling step. After this, the ingredient is grounded into a fine powder, which is then mixed with water. The mixture is cooked and then undergoes a fermenting phase. At this stage, ethanol fuel is produced and the liquid ethanol is separated from the fermented mixture, which some solid product is taken out. It’s in this stage that ethanol is purified in 5 hours to remove any impurities. Subsequently, a penultimate stage which is storing is carried out. It then leads to the final stage of the process where this ethanol is bottled and ready to be delivered to retailers
