Composting ToiletAt RTB, we believe that we must value all of our resources. Therefore, we have implemented the use of urine diverting composting toilets in our facilities. Unlike flush toilets, the urine diverting composting toilet doesn’t create “waste.” By actively composting and diverting urine, we (and all of the biological critters & decomposing microbes) hope to turn our “waste” into a fertilizer treasure trove of beautiful soil and liquid fertilizer that will eventually be put back on the land.

Pee-cycling is a way that we can divert urine away from the main sewage stream, allowing the nutrients to be recycled rather than treated as a waste product. On the website this section After a period of extended storage (> 6 months) urine can (in theory) be spread as a natural fertilizer. However, the biggest unknown at this point is how to do this within the regulatory structure we currently have, therefore this still remains in a theoretical space, here at RTB, and we hope to spread it in the future but the future is not here yet.

Another major benefit of pee and poo-cycling is that it doesn’t use any of our most precious resource, water. Flush toilets use between 1-7 gallons of water with every flush. This means that over 25% of household water use goes, literally, down the toilet to either a septic system or wastewater treatment plant, both of which can impact the environment and utilize more energy and harsh chemicals to treat it.
