The diagram illustrates the cyclical process involved in producing ethanol, a renewable biofuel made from plants.
Overall, the production process involves three main stages: pre-processing, processing, and usage.
At a glance, tress and plants grows sunlights and carbon dioxide grow. Once mature, they are harvested using tractors and sharedded by large machinery to extract cellulose. This cellulose is then transported to processing facility, where is converted into sugars.
Macrobes are added to the sugar to initial fermentation, which produces ethanol. The ethanol is subsquentaly used as a fuel foe various modes of transport, such as car, trucks, and airplances. During the process in vehical machines, carbon dioxideis generated and realsed into the atmoshphere. This gas is the absorded and used as apply again by plants and tress, completing the cycle.
