The diagram illustrates the principal steps of producing ethanol, a type of biofuel. In general, it is obvious that the biofuel production cycle includes two main phases: harvesting and pre-processing plant materials, converting them into ethanol through chemical processes used to fuel means of transportation, and after that the cycle restarts.
In the first stage of the process, the trees are harvested when they attain sufficient growth and are ready for production.
Next,
they will be carried to the factory where they are torn into small pieces and turned into cellulose materials. Linking Words
