In the context of which one of the following are the terms ‘pyrolysis and plasma gasification’ mentioned?

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.
