| A. | It converts the waste into solid, liquid and gas of which the resultant liquid and gas can be used to produce energy. |
| B. | The process occurs at a temperature above 430°C at atmospheric pressure. |
| C. | The process occurs under high pressure at temperature above 430° C. |
| D. | It is a thermo chemical decomposition of organic waste |
| Answer» B. The process occurs at a temperature above 430°C at atmospheric pressure. | |
