You can put some in there, but don't let it exceed 10% of the pile. It does contain some nutrients that can be useful. It shouldn't be used to control insects in the pile, as proper heating and turning of the pile does that. But if you are just trying to find a use for it... Sure, you can throw anywhere from 2 to 10 percent into the pile, safely.

Other than that, there are some other things that you can use it for:
