For centuries, people have been treating urine as waste, washing it without a second thought. But what if this daily product can play a role in raising tomorrow’s food?
In the rural areas of Vermont, a group of farmers and scientists prove that urine is not just something to dispose of – it is an unused resource that can enhance crop yields, reduce the reading of synthetic fertilizers, and help limit water pollution.
Through PeaceCling, the Rich Earth Institute (Rei) collects urine from over 250 Windham county participants (about 12,000 gallons worth) to be used as fertilizer, BBC reports. After collection, the urine is pasteurized to eliminate pathogens and then stored until it is ready for use in the agricultural land.
While “PeaceCling” may sound unconventional, historical records suggest that the use of urine as fertilizer dates from ancient China and Rome. And practice has many advantages.
Urine is rich in nitrogen and phosphorus, the same essential nutrients found in conventional fertilizers, but without the environmental fee. Synthetic nitrogen fertilizers rely on dirty fuels, especially natural gas, while phosphorus production generates toxic waste.
Urine, on the other hand, is freely available and constantly completed. “Everyone peeking out,” said Betsy Williams, a long -time participant in the Vermont nutritional (UNRP) nutrition program, according to the BBC. “[It’s an] unused resource. “

Scientific research supports its effectiveness. Studies published in The Innovations as key to The Green Revolution in Africa Journal, shared by Springer Nature, found that crops such as cabbage and spinach see more than double when fertilized with urine compared to fertilization. Even in soils poor in nutrients, it helps plants flourish, making it a promising solution for sustainable farming.
Peecycling also tackles a major environmental challenge: water pollution. Usually, urine enters the wastewater systems where its nutrients are not completely eliminated. When put into rivers and lakes, these nutrients load algae, bloom, stifle waterways and kill water life.
“Our bodies are creating many nutrients. At the moment, these nutrients are not only lost, but in fact they create many problems and are damaging to the current,” Rey Jamin Suspak’s CEO told the BBC.
By redirecting urine to agricultural land instead of waterways, Peacecling helps to limit this pollution while supporting food production.
Despite its potential, the scaling of urine recycling has its challenges. Regulations often group urine with wastewater, which makes it difficult to integrate into agriculture. In order to navigate this, Rei works closely with the Ministry of Environment Ministry of Vermont to develop a regulatory path.
“The Rei is certainly a blazing path here in Vermont and I think we have been able to find a working, regulatory road,” Eamon Twohig, the agency’s program leader, told BBC Eamon.
Transport also poses logistics problems. Because urine is heavy, moving long distances can be expensive and carbon. To allow this, the Rei rotation company has developed a freezing concentration system that reduces the volume by six times, which facilitates storage and transportation.
While some may find the idea of collecting urine unattractive, Ray’s studies suggest that ICK’s “ICK factor” is often overworked. Pharmaceutical pollution is a more common concern, but preliminary studies show that even fertilized vegetables contain only traces of substances such as caffeine and acetaminophene.
“You will need to eat a rather uncensory amount of lettuce, every day, for a long time than you can live,” to consume the equivalent of a cup of coffee, “added a major.
As extreme meteorological events and water pollution are becoming more and more problems, rethinking waste management is more important than ever.
“In [the United States]People don’t really think where their waste is going, “Williams noted.” This is a new border for people. “
But as Vermont’s PeaceCling pioneers prove, sometimes the most refurbished resources can offer the largest solutions.
