The terms `pyrolysis and plasma gasification` are mentioned in the context of waste-to-energy technologies.

Pyrolysis is a thermal process in which waste materials are heated in the absence of oxygen to break down the molecules into simpler compounds, which can be used to produce fuels, chemicals, and other useful products. The process helps in reducing the volume of waste that needs to be disposed of and can also help in reducing greenhouse gas emissions.

Plasma gasification is a process that uses a plasma torch to convert waste materials into a gas that can be used to generate electricity. The waste materials are heated at high temperatures in the presence of a plasma torch, which creates a gas that can be used to generate electricity. The process can also help in reducing the volume of waste that needs to be disposed of and can be used to recover valuable materials from the waste stream.
