And how does a portable potty become a composting toilet?
What goes in that provides the composting element?
Lots of people use kitty litter, then dispose of the plastic bag with the litter and human waste.
Is this actually composting, or something else?
Composting toilet means that the effluvia is compost-able and ready to begin the composting process.
Composting is a long-duration process. The fastest composting methods are moderately labor intensive
and require attention at a minimum every other day. Compost can be ready in about 30 to 40 days in
this manner.
Traditional composting takes place over the course of months, typically 8 or 9 months from the time the
compost bin is filled until it is usable.
When composting human waste (or other feces as opposed to manure) the typically recommended compost
time is 2 years. With hot-composting it is safer to use the finished compost at the end of the first year, but
since the parasites that may be present in feces from carnivores/omnivores are more compatible with humans
this extra safety margin is recommended.
The take-away from compositing toilets is NOT compost. It's not even CLOSE to being compost. It's a nutrient-
rich block of biological material that is ready to be added to a compost pile where it can be slowly consumed
and transformed by various bacteria, fungi, insects, etc. into usable material for gardening and/or agriculture.
If you are going to compost your own material from a composting toilet, then I recommend using sawdust,
coco coir, or peat moss as your drying media. Kitty litter (unscented) made from clay will work, but generally
the material you get after composting is less desirable if it has too much clay or other inorganic material in it.
