Explanation:
The terms "pyrolysis and plasma gasification" are mentioned in the context of waste-to-energy technologies. Pyrolysis and plasma gasification are methods used to convert waste materials into energy, typically in the form of heat, electricity, or fuels. These technologies involve the thermal decomposition of waste materials at high temperatures, often in the absence of oxygen, to produce valuable products or energy. They are considered as potential solutions to reduce waste volume, recover energy from waste, and minimize environmental impact.
