The images below illustrate the process and potential of how garbage can be recycled to create aviation biofuel. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
SAMPLE ANSWER
The pictures illustrate the process of how rubbish can be treated to create biofuel for planes and the benefits of this.
The process starts with the collection of rubbish and its delivery to a plant where it is changed to biofuel. The details of the actual process are not given. The biofuel is then transported to its end use of fueling aircraft.
There are a variety of advantages to this, namely that the process is clean, scalable, efficient and reliable. The images also give some example data on how trash can be converted to biofuel. Firstly, it is said that the total amount of U.S rubbish that is generated in one year can create 10 billion gallons of biofuel oil, which is triple the amount of fuel used in one year by a major airline. Secondly, it is said that the average American produces over 750 kilograms of rubbish every year, which has the energy potential to create 25 gallons of biofuel.
The large figures look impressive, but if the total rubbish of the whole of the Unites States can only produce fuel for three airlines, this does not appear to be very significant. In addition, the capital costs of creating the plants and the costs of generating the biofuel are not taken into account.
