Previous research has shown that antibiotic-resistant DNA can be found in urine, raising the question of whether fertilizers derived from it might carry over that resistance. Urine is 95 per cent water, 2.5 per cent of which is urea, and a further 2.5 per cent of which is a mixture of minerals, salts, hormones and enzymes. Epsom salt 3. Not only that, we all have a constant, year-round supply of it - and it's free! Recycled and aged human urine can be used as a fertilizer with low risks of transferring antibiotic resistant DNA to the environment, according to … New research from the University of Michigan found that recycled and aged human urine can be used as fertilizer with low risks of transferring antibiotic resistant DNA to the environment. Fortunately, we've discovered that increasing the pH of urine to make it alkaline ensures the urea doesn't break down or end up smelling really bad. Using this technique, we've developed a process that can reduce the volume of urine and transform it into a solid fertilizer. I have run tests to check for coloforms in aged urine and … “Urine Separation — Closing the Nutrient Cycle,” the exhaustive Swedish study of using urine as a fertilizer, compares the pros and cons of using solid human waste and liquid human waste to help grow crops. When applied to the soil, both will convert to the ammonia and nitrogen needed by plants. “Our current agricultural system is not sustainable, and the way we address nutrients in our wastewater can be more much more efficient.”. Today, municipal treatment systems don't totally remove these nutrients from wastewater before it's released into rivers and streams. The research was funded by the National Science Foundation. Jan. 24 (UPI) — Recycled and aged human urine is a safe alternative to traditional fertilizers. The team conclude that, provided urine is aged – as is the case in most systems designed to collect urine for fertiliser – it is unlikely to spread antibiotic resistance if used on crops. 00:00.
