GT World Watch: Urine Farming At Its Best
Welcome to episode 3 of GT World Watch - our look at the green news that is a bit out there and may have been missed by your local news reports.
Today, Sweden makes the GT World Watch for an unprecedented second time with their urine separating toilet. Also used in Australia, the urine separating toilet has the potential to separate liquids and solids in order to save millions of dollars in sewage treatment costs and at the same time save water and create tonnes of fertilizer.
That’s right, the urine becomes liquid fertilizer. This high quality organic fertilizer reduces farmers’ costs and helps to avoid the long term environmental problem caused by chemical fertilizers.
In Sweden, a test market in the council of Tanum is recycling urine for use as fertilizer on farms. All new homes in the area are required by law to have special toilets that separate urine and pipe it into a holding tank that farmers access at regular intervals. Experts say this is better for the environment because the special toilets use less water. And less energy is utilized at treatment facilities. Most importantly, human urine has the most concentrated source of phosphorus, which is a vital ingredient in agricultural fertilizer. Tell that to the neighbour with the great lawn.

Comments are sorta kinda broken right now. We're working on it but to save energy can only work in daytime when solar system is at peak performance.
