Leviticus 9:17-21

And he brought the meat offering, and took an handful thereof, and burnt it upon the altar, beside the burnt sacrifice of the morning.

Meat offering ... wave offering. It is observable that there is no notice taken of these in the offerings the priests made for themselves. They could not bear their own sins; and therefore, instead of eating any part of their own sin offering, as they were at liberty to do in the case of the people's offering, they had to carry the whole carcasses "without the camp, and burn them with fire."
