hi cythia,
My main point was the peat etc in a bucket or chamber pot or commode as contrasted with the usual latrine method which stinks to high heaven, has loads of bugs, and is just disgusting. If one's water goes out and one cannot use the usual plumbing, the carbon dry added to one's donations sure beats the alternatives.
Now diluted pee and ashes
do help the garden, esp tomatoes, but added in autumn, not in spring. Thoroughly letting Nature process this stuff is crucial to hygiene. For solid matter one year is the minimum compost time.
One year. Then - and only then - is it hygienically safe. If I did not know the health of all donors I would let it sit 2 years just to be safe. In a properly built compost pile, not just tossed somewhere.
For a true marsh treatment site or whatever like that research would need to be done, which I have not done beyond casually reading an article now and then. I kow marsh treatment can work if done correctly. Those interested should research it. My personal focus is just as an emergency backup to normal plumbing.
Bucket and bag of peat in the garage is one of those just in case things that hurts nothing, is fairly cheap and easy to do, and if one ever needs it one will be soooo glad one has it.
Folks may notice I am fairly big on cheap and easy and hurts nothing to do it. Won't hurt, might help sometime, along with how much would I really really wish I had it should events make the item in question something I'd sooo wish I had. I'm not interested in going overboard or into debt or any of that. One should do what one feels comfortable with, what comforts and is affordable to the person or family. It's a bit of peace of mind. eh. That's all.
