Which term is used to refer to the total output of waste material incinerated?

The term that refers to the total output of waste material incinerated is known as "burning rate." This term specifically refers to the measure of how much waste material is being converted into ash and gases through the incineration process over a given time period. A higher burning rate indicates a more efficient incineration process, where larger quantities of waste are being effectively reduced.

While the other options relate to waste processing or efficiency, they do not directly define the measure of the total output of waste material incinerated. For instance, "burning efficiency" pertains to the effectiveness of the combustion process, "processing rate" might refer to how quickly waste is processed in general, and "incineration rate" could imply the speed of incineration but does not specifically denote the total volume of waste output. Thus, "burning rate" is the most accurate term in this context.
