Check out my video on a composting toilet I made from a scrap pallet and some left over plywood and made my own pee separator from an old plastic vinegar bottle. It is important to keep #1 and #2 separated to keep the odor down. Keep that poopy dry and use dry cover like sawdust, use enough to cover well, if there is still an odor use more sawdust.
Here is a link to my video
