Waste-to-energy - crux
Question
Which one of the following statements best reflects the crux of the passage?
Options
Generation of energy from municipal solid waste is inexpensive.
Biomethanation is the most ideal way of generating energy from municipal solid waste.
Segregation of municipal solid waste is the first step in ensuring the success of waste-to-energy plants.
The biodegradable component of India's municipal solid waste is not adequate to provide energy from waste efficiently/effectively.
Explanation
The passage outlines the structural workflow of waste processing, noting that waste-to-energy plants fit sequentially "after segregation". The selection of appropriate conversion tech depends on isolating the raw material properties (biodegradable fractions vs. calorific value). Because these industrial processors rely entirely on uniform compositions to work, sorting the waste at source is the foundational precondition for the plant's operational success[cite: 3407, 3408]. Option (c) reflects this core dependency. Option (b) is a partial trap that over-generalizes the concluding sentence on biomethanation, while options (a) and (d) directly distort cost and volume metrics.
Answer: (c).
