Compugeek, bio-waste isn't much of an issue in the middle of no where, for example hiking with no trail or going off a seasonal trail the environmental impact is minimal (this is my opinion and I have no hard evidence backing me up)

I would burn it, but that takes time and smells to high heaven.

Well maybe not as long with just the contaminated tissue.

I just try to leave it as clean as it was before I took a dump.
