Human urine, a valuable resource as fertilizer for sustainable urban agriculture, study concludes

Researchers develop tiny glass orbs with unbelievable capabilities — and it could completely transform food production

Scientists have created glass fertilizer beads that release nutrients slowly and steadily, making them an earth-friendly alternative to conventional fertilizers, reported Phys.org. We all need to eat, and farmers need fertilizers to grow enough food for everyone. But traditional fertilizers often wash away into waterways or release gases into the air, causing toxic algal blooms and contributing to our overheating planet. These new glass beads ar…

Human urine, a valuable resource as fertilizer for sustainable urban agriculture, study concludes

The reuse of human urine would allow for the production of sustainable fertilizers for urban agriculture, with significant environmental benefits, a new study concludes. The research evaluates the environmental impact of nitrogen recovery from the yellow waters of buildings. In addition to promoting sustainable agriculture, it would reduce carbon dioxide emissions and water consumption.

Scientists Turn Human Urine Into Sustainable Fertilizer

Researchers at ICTA-UAB found that human urine can be reused as a sustainable fertilizer for urban agriculture, helping reduce CO₂ emissions, water use, and reliance on non-renewable resources. Reusing human urine to produce sustainable fertilizers could offer major environmental advantages for urban agriculture, according to a study by the Institute of Environmental Science and Technology [...]

Chemical fertilizers are synthetic chemicals used in agriculture to provide essential nutrients to plants. These fertilizers are manufactured from chemical raw materials and are designed to increase crop production by providing nitrogen, phosphorus and potassium, which are macronutrients essential for plant growth. However, they have negative impacts on the environment and human health, such as water pollution, loss of biodiversity, eutrophicati…

The color of urine can communicate many things about your health. Doctors also use color as one criterion in diagnosing a patient, although it is certainly not the only one. The color of urine can vary from light yellow to deep brown. Normally, urine should be light yellow, which indicates good hydration and normal urination. The color comes from urobilin, which is a breakdown product of hemoglobin. What can the colors mean? Do you dare to take …
