The diagram illustrates the sequential process involved in the manufacture of ethanol from biomass, delineating eight distinct stages.
Overall, the manufacturing process encompasses the cultivation of plants and trees to the final production of ethanol, marked by several key phases including harvesting, processing, and ethanol creation, forming a continuous cycle.
The initial stage entails the cultivation of plants and trees which absorb energy from sunlight and carbon dioxide. Following this, the plants and trees are harvested and subsequently ground to a finer texture during the pre-processing stage. In the subsequent stages, cellulose is extracted from this material. The next step involves a chemical process to produce sugars through the addition of microbes, culminating in the creation of ethanol that can be used as a biofuel for vehicles, such as planes, cars and trucks. Finally, these vehicles release carbon dioxide into the atmosphere, which once again functions as a source of energy for the growth of plants and trees.
