A Urine Based "Potion" Can Act as a CO2 Absorbent, Institute of Agricultural and Fisheries Research and Training Study

The ocean, the ground, rocks and trees act as carbon drains but are far from places where greenhouses gases are concentrated, especially CO2. A Spanish researcher has proposed human, agricultural and livestock waste, such as urine, as a way to absorb this gas. Absorbing the large quantities of carbon dioxide and other greenhouse gases present in cities would require millions of tonnes of some naturally occurring substance. A study published in the Journal of Hazardous Materials suggests urine as a reactive. As a resource available across all human societies, it is produced in large quantities and is close to the pollution hubs of large cities.
