Consider the following statements about the process of Pyrolysis/Gasification.
1. In this process, waste is directly burned in the presence of excess air (oxygen) at high temperatures (about 800°C), liberating heat energy, inert gases, and ash.
2. Combustion results in 65–80% of the organic matter's heat content to hot air, steam, and hot water.
3. The steam generated, in turn, can be used in steam turbines to generate power.
Which of these statements is/are correct?
