In the Passive house projects I have looked over, I see lots of cellulose being used with a very aggressive packing scheme.

It is packed tight enough that settling is not an issue.

The walls are sealed up tight enough that air passage is not an issue, so 'dust' is not an issue.

The thermal gradient is controlled so that the dew point is never reached inside a wall.

The energy to make it is markedly less than fiberglass.

And there's plenty of carbon being sequestered.
