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

* Pyrolysis and plasma gasification are both thermochemical processes used to convert waste materials (organic or inorganic) into usable products.

* Pyrolysis: This process involves heating organic materials (like plastic, and biomass) in an oxygen-deficient environment, leading to decomposition into various products like syngas (a mixture of gases), bio-oil, and char.

* Plasma gasification: This technology uses high-temperature plasma to break down waste materials into syngas rich in hydrogen and carbon monoxide.

* Both processes offer a potential solution for waste management and energy generation. They can convert various waste streams into usable fuels or feedstock for further processing.
