Band 6+: You should spend about 20 minutes on this task. The diagram below shows how ethanol fuel is produced from corn. Summarise the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The data illustrates a step-by-step process of how raw corn is made into ethanol fuel ready to be exported and used, all within 8 steps.

Overall, the process demonstrates multiple step sectors of transformation, including processes of storing and transporting to destined places. Additionally, the only external material that can be seen is water.

The first step includes gathering the raw corn, which will be the core material in the process. These collected corns would be stored in places before the milling process began. After the corns are milled thoroughly and finished, the cooking process would take place within a total of 4 hours and an additional 48 hours of fermenting. Consequently, the fermented and milled corns would be separated into two categories: liquid and solid by-products. After the operation, the difference between liquid and solid remains has been established; the liquid, which is to be used as fuel, would be purified for 5 hours to become the processed ethanol fuel. After the purification of the liquid has been established, the recently processed ethanol fuel will be stored for some time before being sent and transported to meet demand.
