New research from SLU now confirms that the technology to dry and preserve the nutrients in urine could become an important piece of the puzzle in sustainable agriculture. Every year we flush away large amounts of plant nutrients that could do wonders in our gardens. With the Towa Gold Pot, it becomes easy to collect the urine and create your own golden water – a nutrient-rich fertilizer that both saves the environment and produces lush plants.
We humans pee out about 4 kilograms of nitrogen, 1 kilogram of potassium and 0,3 kilos of phosphorus every year. These are exactly the nutrients that plants need to grow strong and healthy. Yet these are washed away in our sewage systems instead of being used in cultivation.
When you use The gold jug Towa You can easily collect the urine, dilute it with water and create golden water – a natural, free and organic fertilizer.
A study at the Swedish University of Agricultural Sciences (SLU) has investigated how urine can be dried and concentrated on site to create an even more sustainable fertilizer. By raising the pH value and using materials such as magnesium oxide, calcium hydroxide, biocol and wheat bran, the researchers managed to reduce the volume of urine by over 90% and at the same time preserve up to 74% of nitrogen.
Every person pees out approximately every year 4 kilograms of nitrogen, 1 kilogram of potassium and 0,3 kilos of phosphorusThese nutrients are important for plants and can be used as fertilizer. However, they are rarely recovered in today's wastewater treatment systems - they are often flushed away and lost.
Researchers have investigated how to dry urine in situ and preserve its nutrients so that it can be used as fertilizer. By separating the urine and drying it, the volume is greatly reduced and the nutrient content is increased.
In a study at the Swedish University of Agricultural Sciences, different materials were tested that could help dry urine and raise the pH value so that nutrients are preserved. The researchers used, among other things magnesium oxide and calcium hydroxide as basic substances, and biocol and wheat bran as additional material.
The urine was dried at approximately 48 degrees and all methods reduced weight by more than 90 percent. The drying speed was high – over 19 kilograms per square meter per day.
In terms of nitrogen retention, the results were good: magnesium oxide retained approximately 67 percent of the nitrogen, and the other mixtures retained over 74 percentSome nitrogen was lost as ammonia, probably because a large portion of the urea in the urine had already been converted before the experiment began.
The results show that it is possible to sustainably convert human urine into a concentrated, nutrient-rich fertilizer – directly where it is collected. This could reduce the need for artificial fertilizers and contribute to a more circular agriculture.
Although SLU's research is about drying and storing urine, it shows how valuable this resource actually is. With The gold jug Towa You don't need advanced equipment – you can directly water your flowers, vegetables and shrubs with golden water and get clear results.
With the Towa Gold Jug, you can start returning nutrients to the soil today – without waiting for future technology. Research confirms what we gardeners already know: gold water is a simple, effective and sustainable solution for greener gardens and a healthier climate.
