What I don't get is the composting toilets. How do you dispose of the waste from them without violating zoning laws, etc.?

When the composting is complete - the waste is not a bio-hazard substance. All liquid is 'evaporated' - assisted by a heater to increase evaporation.

The resulting material to be composted is about 10 percent of the input material. A properly operating composting toilet can handle the waste of 4 or 5 people and only produce a few pounds of composted material each week.

Here is a link to a unit specifically designed for RV / Marine use - Evergreen RV / Marine Composting Toilet

I've seen a composting toilet installed in an Airstream. A family of three used the unit. The owner showed the state park manager his material to dump. There was no smell. He used sawdust as an additive, and his approx. 5 gallon trash bag of waste was according to him - two weeks of waste from three people.

Made me wonder about running 30 gallons of water and waste through the black tank every 8-10 days. Sometimes we choose less desirable camping spots because it has a sewer connection.

He used a 42 gallon Blue Boy for gray water collection and disposal.

Interesting that this second (third?) hand experience is so different from the experience of people who actually have composting toilets -- the real kind, that hold a year worth of waste. They say it still stinks after the year is up.

And, of course, the manufacturers say you need two years of composting before it is safe.

But give it a try, let us know how it works for you and whether it was worth the thousands of dollars.
