The diagram below shows how a biofuel called ethanol is produced. Summarise the information by selecting and reporting the main features, and make comparison where relevant.
The given diagram illustrates the manufacture of a biofuel called ethanol.
Overall
, that is
a chemical process consisting of 3 main steps, starting with trees getting energy from sunlight and carbon dioxide and finishing with public vehicles releasing the carbon dioxide into the atmosphere.
Having looked at the diagram for more details, we can see that first of all, the crop is qualified to be harvested by a harvester. Secondly
, these plants experience pre-processing in factories where they are crushed in mills and changed to cellulose. Next,
the processed cellulose will undergo chemical processes and be converted to sugar.
Thirdly
, the process continues with the sugars combined with added microbes and producing ethanol. After that, this
amount of ethanol is used for operating public transport. Next,
these public vehicles send out carbon dioxide into the atmosphere. Finally
, this
gas is synthesized with sunlight with the goal of providing energy to the plants and this
cycle continues again forever.Submitted by ieltswritingpracticedl on
