The diagram below represents the process for producing biodiesel. Summarise the information by selecting and reporting the main features.
SAMPLE ANSWER
The diagram shows the process of producing biodiesel as a renewable circle of treatments and usage.
The process starts with energy from the sun being harnessed by the growth of a renewable resource, such as rapeseed or algae. This process also uses carbon dioxide from the atmosphere. This renewable resource is then harvested and oil is extracted in an industrial plant. A useful by-product is a high protein residue that is used as food for livestock. The extracted oil is then processed in another plant into biodiesel. This also produces a useful by-product, this time glycerine, which is used in the cosmetics and food industries.
Biodiesel can be used by a variety of vehicles with existing technology. Vehicles using biodiesel give off carbon dioxide into the atmosphere and this is used by the original resource in order to grow, thereby completing the renewable circle.
It is not clear from the diagram whether there are any other emissions associated with using biodiesel, so from the information given, the use of biodiesel seems to be an environmentally attractive alternative fuel.
