The provided illustration outlines the process of generating a biofuel. This process involves nine distinct stages, commencing with the absorption of natural energy including sunlight and carbon dioxide by plants and culminating in the supply of fuel for vehicles.
Overall, the process can be characterized as cyclical. It begins with the growth of plants and trees by the sun rays and the greenhouse gas. Subsequently, there are several steps to create ethanol related to agriculture and formulation methods. The process concludes with emissions released by transportation units.
The primary stage of the diagram entails natural energy including sunlight and carbon dioxide absorbed by plants and trees for the growth. After, the vegetation of the previous step is harvested to prepare for the processing. Once these steps are completed, the cellulose is collected, being important for the rest of the process.
Following this, the cellulose is acquired from the previous phase and goes into the processing phase. During this stage, sugars are formed due to several scientific phenomena. Thereafter, the addition of microbes to sugars produces ethanol. This step is crucial because the ethanol created can be regarded as the biofuel. As a result, several sources of fuel for vehicles are established. Finally, transportation units burn up the ethanol, releasing carbon gasses as waste into the atmosphere and the cycle restarts.
