Question

Green fuel is the fuel obtained from:
A. Bio-waste
B. Metal waste
C. Plastic waste
D. Chemical waste
E. Electronic waste

Answer 1

Hint: Green fuel is a type of biofuel. Green fuel is considered to be more advantageous and safer for the environment as compared to fossil fuels. This is because they cause very less pollution as compared to the traditional forms of fuels used.

Complete answer: Green fuel is the alternative source of energy and a future step towards sustainable development. Green fuel is obtained by the process of distillation. When plants and animal materials are distilled then biofuels are produced. The crops are classified as sugar-producing and oil-producing crops. The sugar-producing crops are fermented to produce ethanol. Oil-producing crops are processed to produce diesel or biodiesel. Nowadays non-food sources and other biological wastes are also recycled to produce biofuels. Finding more alternatives to biofuels enables us to be less dependent on fossil fuels. Green algae are also being used to produce biofuels. It is because algae have very high oil-content in them. Moreover, the cultivation of algae is very easy and takes almost no time. One acre of green algae can produce two hundred times more oil than one acre of corn.
Thus, based on the above information we can conclude that Green fuel is the fuel obtained from Bio-waste.
Hence, the correct answer is option A.

Note: Some people consider that the term green fuel is misleading and there is nothing like green fuel. This is because the extraction of the fuel from the crop and the fermentation process causes a considerable amount of pollution that is equally harmful and damaging to the environment as is the burning of fossil fuels.
