I'd guess that "heat" means something over 100 degrees Fahrenheit for a sustained period. This is to allow the bacteria to break down the pathogens and make feces into compost.
It seems to me, from DWH, Cat Jockey, and the original poster, that the value here is not that you create compost, or that you decontaminate the waste in a reasonable amount of time. The value is that by separating the waste into solid and liquid, you can extend the effective capacity of your holding tanks. Each, on its own, is easier to dispose of than when you mix the two.
