Our Composting Toilet opened for business in 2007, at the
John Janzen Nature Centre. The toilet shows that we can compost even
that stuff.
Visitors to John Janzen Nature Centre and the Compost Education Centre have been peacefully
contributing ever since. On August 24
th, seven compost fanatics met to harvest the Composting Toilet for the very first time.

How it works
Wood chips get mixed with the "
fresh compostables" - liquids and solids - in the toilet. Micro-organisms thrive on both types of nitrogen- and carbon-rich materials to break down the waste. Then the whole batch is gets stirred, regularly, to introduce new waste for the organisms.
We have been surprised by the Composting Toilet. Most of all, it's taken almost six years to have enough finished compost.

Harvesting the finished product
First, we dug a trench near our perennial plants - away from food crops. Next, we dug the trench again. This makes a trench that is
doubly-deep.
Then we harvested finished compost and mixed it into the trench, along with some soil. Finally, we topped the trench with the layers of soil.
When finished, the compost amends the soil and encourages roots to develop deep. We made sure to keep this
humanure compost away from food crops and away from contact with visitors.
Special thanks to those MCRs who helped with harvesting: Maureane D., Mary-Jo G., Hannah H., Andrew J. and Megan M. Our tireless organizer was Ella W., our compost educator extrordinaire (and summer staff).
Most of all, thanks to Mark S.
He has tended the Composting Toilet for more than 5 years. He is the first one to stir the "
compostables" in spring. He preps the "
catchment" at the end of fall. And he replenishes the wood chips and air fresheners in the dead of winter. Thank you, Mark.
