The illustration demonstrates the cycle of manufacturing a biofuel called ethanol.
Overall, there are nine steps employed in the process, starting with energy being absorbed by plants and trees, followed by the conversion of energy into cellulose and ending with the produced ethanol being used by various types of vehicles.
The first four stages aim to turn energy into cellulose. Initially, vegetation absorbs energy, which includes sunlight and carbon dioxide from the atmosphere, to grow. After that, plants are harvested before being conveyed into pre-processing by a chipping machine. Subsequently, cellulose is extracted, ready for the next step.
The remaining stages produce a biofuel called ethanol. The cellulose undergoes chemical treats in order to produce a new substance called sugar. In the following stagestage, the manufactured substance is added to microbes, leading to ethanol’s appearance. At the end, the produced biofuel is used as energy for transportation, and the emissions released into the atmosphere from those, renewing the process cycle.
