The reuse of human urine would allow for the production of sustainable fertilizers for urban agriculture, with significant environmental benefits. This is the conclusion of a study conducted by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), which evaluates the environmental impact of nitrogen recovery from the yellow waters of buildings. In addition to promoting sustainable agriculture, it would reduce CO2 emissions and water consumption.
Humans are having a highly detrimental impact on biodiversity worldwide. Not only is the number of species declining, but the composition of species communities is also changing. These are the findings of a study by Eawag and the University of Zurich published in the scientific journal Nature. It is one of the largest studies ever conducted on this topic.
Technology developed by MIT engineers makes pesticides stick to plant leaves. With the new system, farmers could significantly cut their use of pesticides and fertilizers, saving money and reducing runoff.
