"We are delighted to announce a significant milestone that was set almost ten years ago: the production of a dry urine fertiliser with the aim of replacing solid chemical fertilisers in agriculture. In March 2023, we achieved a major breakthrough by successfully producing the first 20kg of solid urine-based fertiliser with a confirmed nitrogen content of 15%. This accomplishment was made possible through the collection of over 4,000 liters of urine on Gotland, a large Swedish island in the Baltic Sea, using the Touch Down system. The collected urine was then dried by Sanitation360 AB, and the final drying and production processes were carried out at SLU (Swedish University of Agricultural Sciences) in Uppsala.
The next step in our journey is to evaluate the performance of urine-based fertiliser in agriculture, comparing it with conventional chemical fertilisers. In April, we initiated a barley field trial spanning over 500 square meters, where we seeded the field with our latest dried urine fertiliser. As the barley grows, we will closely monitor and assess the results, and we look forward to sharing our findings with you.
To provide a firsthand experience of our ongoing work, we are hosting a Demo Day on June 13th at 16:00 on Gotland. This event will allow you to see, touch, and even smell the fertiliser that we are producing. Additionally, you will have the opportunity to observe the toilets that facilitate the urine collection process. For more information about the Demo Day, please visit: fb.me/e/153OuqStl "
