Well, I can't get any info about the poop tubes from the link provided so can you give me a breif explanation as to what these are and how they are built? It would be greatly appreciated!
The poop-tubes are described in the book .. and many other great ideas!! I would highly recommend buying the book if at all possible. I have made several of the poop-tubes .. so I will give you a quick description.
Using 4" sewer-pipe, pipe-caps and clean-out screw-caps, you will join them together in a length suitable for your trip out (and about) that will easily fit in your vehicle or on a back-pack.
You will then have a second tube made up that will have your "cleaning supplies" consisting of toilet-paper, paper-towels and kitty-litter. I put the kitty-litter in zip-lock baggies separated from the zip-lock'd important-papers.
You will then release your liquids first and hold the solids. Lay out on the ground the paper-towel and sprinkle with kitty-litter. Drop your solids on the paper, and then when you are done, sprinkle more kitty-litter over the top of the solids. Pickup the corners of the paper-towel and fold into an envelope.
Initialize the poop-tube with kitty litter, then drop the whole envelope into the dirty-collector poop-tube. Sprinkle kitty-litter over the top and then re-seal the tube. Repeat as necessary.
When you arrive at an out-house or similar place to dispose of the solids - do so. When you get a chance to wash out the poop-tube for storage - use disinfectant and clean as best as possible. I personally like to use Spray-Nine as the disinfectant ... Mr.Clean also works well.
