I have a lot of experience with the unconventional animals, many of which have much more potent odors than human waste and sawdust does great. Cedar has great absorbency for liquid and odors, it also helps significantly that cedar generally has a really nice smell to it. I've even composted the waste before and it doesn't change the odor given off by the heap. If you still frequently cut your grass, you're going to be smelling composting plant matter far more than the human element. Personally, if I had the land available, I wouldn't have a problem with a composting toilet on my property. However, I'd probably stick with a low-water toilet for inside the house.
