A caveat here, though: There may be local laws and building codes regulating the addition of composting toilets to your home or business and the handling of composted waste, especially if you live in a city. Check those out before you install your system….
Specifically, look for a unit that complies with the American National Standards Institute’s standard for composting toilets….
Here are a few more facts:
>> For a year-round home for a family of four, the typical cost of a composting toilet is $1,300 to $6,000. Compared to the cost of water alone throughout the lifetime of a toilet, this is really a pretty nice savings. They are more expensive to operate than low-flow toilets, but they are more affordable than septic systems.
>> You can use a composting toilet anywhere, including places that aren’t connected to a city or private sewage grid, or where building a septic tank is pricey or difficult.

>> It is more resource—and cost—effective to treat waste onsite, and by using a composting toilet, you eliminate your share of harmful flows into rivers and oceans. Plus, humus is much safer than the residue from either waste-water treatment plants or septic systems.
>> When you use a batch system, composting toilets are the most hygienic choice of all. The natural bacteria that makes compost also kills viruses, bacteria and the nasty toxins in human waste.
>> Some toilets allow you to compost vegetable peels and garden trimmings with the toilet waste. How cool is that?
Composting toilets can be the way to go if you don’t want to flush dollars down the drain. They’re also better for the environment, and are the gift that keeps on giving because they are a lasting source of nutrient-rich humus.
