We use these at work. We’re contractors who spend one to a few days at residential addresses working outside. Instead of using the customer’s bathroom, each of our enclosed trailers has a toilet built in, so we always have one accessible at our jobsites.
Since this looks like it would be best used in rural applications with low populations, what benefits does it have over a traditional septic tank system with drain field?
Mainly that you can save a lot of water and potentially use the nutrients in the urine as fertilizer.
Urine obviously has a lot of nitrogen that can be made available to plants, but more importantly, it has a lot of phosphorus. Phosphorus is vital to agriculture, but it is largely mined as a non-renewable resource
