For those that have a dog as a pet, they’ll likely know that their urine can kill grass and plants. The acids contained in the urine will burn away at the lawn. However, if it’s diluted enough, it can actually become an incredibly useful plant fertilizer. That’s the amazing process behind RISE, a carpet that grows crops by urinating on it.
Three Mexican students have been working on RISE for the past eight months: Dominik Bini Falconi, Denisse Ojeda Rodriguez, and Jose Luis Galindo Ortiz. The harvesting system is made from biodegradable products and contains the seeds needed for the plant and filters to make the urine usable to grow the crops. It’s intended for those that live in refugee camps and have limited resources for agriculture.
Dominik explained in a translated report on SinEmbargo that this method provides a way for people to preserve their water instead of using it to grow crops. He believes it provides advantages over standard H2O: “When the urine goes through the filters it eliminates certain substances; Leaves the urine with sufficient nutrients for the plants. In fact, it is even better than water.”
