Prelims 2017 · Environment · Question 97
It is possible to produce algae based biofuels, but what is/are the likely limitation(s) of developing countries in promoting this industry? 1. Production of algae based biofuels is possible in seas only and not on continents. 2. Setting up and engineering the algae based biofuel production requires high level of expertise/technology until the construction is complete. 3. Economically viable production necessitates the setting up of large scale facilities which may raise ecological and social concerns. Select the correct answer using the code given below:
Answer
2 and 3 only
1. Incorrect. Algae-based biofuels can be produced both in marine water and on land using ponds/photobioreactors; it is not limited to seas only.
2. Correct. Algae biofuel production needs advanced cultivation systems, harvesting, extraction and engineering know-how; this can be a major technological limitation for developing countries.
3. Correct. For economic viability, production generally needs large-scale facilities, which can create land, water, ecological and social concerns.
Therefore, statements 2 and 3 only are correct.
