The diagram illustrates the processing of fuel from ethanol.
Overall, the process of making fuel can divided into three main stages: harvesting and keeping followed by processing and finally storing and distribution. Notably, the whole process is complex and requires machinery.
Firstly, the corns are harvested and stored in special place. After separating them in two groups, such as, luquid and solid, the vegetables are fermenting and it takes nearly 2 days. Then products are cooked in water for 4 hours. Then ethanol is purifyied in large machinery 5 hours.
During the next step, are stored and sent to the gas stations by truck.
