The image shows information about manufacturing ethanol.
Overall, it can be clearly that this is a cycling man-made process which consists of 10 stages. Plants, trees and microbes are used by as raw materials in order to be transformed to ethanol.
Firstly, sunlight and carbon dioxide contribute to grow plants and trees. After that, they are harvested by tractor. At the initial stage of process, harvests are used by pre-processing machine which result in cellulose. After that, cellulose go through chemical process in order to obtain a sugar. Next stage consists of union a sugar and different microbes which lead to receive ethanol. These biofuel productions are used in various types of transport, such as cars, plains, trucks and ships. All of them have emissions while working, which impact on environment. This pollution is called carbon dioxide which can used by main element of biofuel production.
