Collecting and recycling urine saves money and supports local economies by conserving drinking water, reducing wastewater treatment costs, producing fertilizer, and improving water quality in marine and freshwater ecosystems.
The portable 5-gallon urinals allow participants to collect urine odorslessly. The funnel assembly screws securely onto the jug and the cloth sleeve improves aesthetics. A ping-pong ball sits inside the funnel, sealing the opening and blocking odors, but floating up when urine needs to pass. When full, users unscrew the funnel, attach a tight cap, and bring full containers to the urine depot.
Waterless urinals have great potential to be used to collect urine. They are used like any other urinal, and many public restrooms have already been fitted with such systems to conserve water.
Urine-diverting flush toilets have a special urine collection basin at the front of the toilet bowl, which catches the urine and drains it to the urine collection tank. Many urine-diverting toilets require little to no water to flush urine, resulting in substantial water savings.
This figure shows the volume of human waste compared to tap water in wastewater. Separating urine from the rest of the wastewater stream at the source has the potential to eliminate 75% of the nitrogen and 55% of the phosphorus from municipal wastewater without making any changes to treatment plants.
Best Septic has collected and transported more than 10,000 gallons of urine to participating farms. Seth True, driver for Best Septic, travels and spring and fall route throughout the country pumping out 55 to 250-gallon tanks of urine from homes.
Best Septic Services of Westminster, Vt., has collaborated with the Rich Earth Institute since 2012, transporting urine to participating farms. They also rent urine-collecting portable toilets for public events, allowing event organizers to provide odorless toilets that produce fertilizer instead of waste.
