In the context of which one of the following are the terms ‘pyrolysis and plasma gasification’ mentioned?
A.Extraction of rare earth elements
B.Natural gas extraction technologies
C.Hydrogen fuel-based automobiles
D.Waste-to-energy technologies
Correct Answer: Option D
Pyrolysis, gasification, and plasma technologies are all thermal processes that utilize high temperatures to break down waste materials.
These processes, like incineration, are used in waste-to-energy technologies.
A key distinction is that pyrolysis and gasification use less oxygen compared to traditional incineration methods.
Therefore, the correct answer is (d) Waste-to-energy technologies.
