Compost Toilets

Our toilets recycle our natural byproducts into a nutrient-dense compost that can be used to fertilize plants, stop erosion, or suppress weeds.

Step 1

Nature Calls

First, you use the toilet like usual, except you'll toss in a layer of sawdust instead of flushing. Our toilets offer a sit-down toilet seat and a urinal, which have separate collection vessels, but everything ends up in the same compost pile.​

Step 2

Odor Control

Sawdust is high in carbon, which balances out nitrogen-rich poop and pee, covers up any smell, and deters flies from getting to the deposits. It also begins the composting process right at the toilet.

Step 3

Hand Sanitizer

We provide our own proprietary blend of glycerin, benzalkonium chloride, and distilled water for a non-alcoholic hand sanitizer. Our blend changes with the seasons to provide the cleanest feel while remaining non-freezing.

Step 4

Making Compost

When the bin is full, our volunteers add it to our compost pile. There, it gets covered in straw and composted.

Step 5

Clean Dirt

The compost pile gets over 131°F, killing all bacteria and viruses within three days.

Step 6

Aging Like Fine Compost

Each pile then ages for a year while the beneficial bacteria inside digest everything and break it down into fine, usable compost.

Step 7

Test, Test, Test

Once the compost is finished, we sample from several areas in the pile and send the compost off for testing to make sure it's safe, clean compost.
