Given is a diagram which illustrates the production of ethanol, a type of environmentally-friendly fuel. Overall, plants go through a series of harvestation and deformation to turn into sugars, then through an addition of substances they become ethanol for distribution to vehicles, emissions from which is absorbed by plants again.
The most reasonable point to start is the trees and plants being collected and put into a machine that pre-processes them into small cellulose particles. By this stage, they are transferred into the laboratory, through chemical processes, form sugars.
Subsequently, minuscule microbes are added to the material which results in the mixture referred to as ethanol. After that, ethanol can be used to operate cars, trucks or even airplanes and the carbon dioxide released by these transportations, together with sunlight, contribute to the growth of another generation of plants and trees, ultimately starting a new cyclical cycle.
