I'll just come out with it straight away: This is a post about recycling urine - or rather the phosphorus, nitrogen and potassium in urine - for agricultural purposes. Too hell with the fancy, schmancy composter - let's hear it for pee-cycling! (O, how I wish I'd coined that phrase...)
Phosphorus is an extremely important agricultural fertilizer, and like many of our other natural resources, its stores are depleting. But urine is one of the richest sources of concentrated phosphorus in the world, and we humans are each making 100 gallons of it per year. So you can take yourself right outside and pee all over your tomatoes and lettuce, if you are the D.I.Y.-type, or you can order one of these handy urine-separating toilets for your home, which funnel this liquid gold into a holding tank, which, when full, is picked up by "urine reclamation" specialists. After standing for 6 months - to kill bugs or bacteria that may have been picked up on the way out of the body - the tanks are emptied all over some lucky farmer's crops. I'm not sure how advisable a D.I.Y.-version of the holding tank would be, but I wouldn't be surprised if there were some hardcore green livers out there who devised their own systems. A low-impact and resourceful, if only a little funky-smelling, way to make that garden grow! Not surprisingly, those oh-so-progressive Swedes are all over this one.
While restocking the world's oil supply is hopeless, and getting the federal government to recognize and help reverse the process of global warming seems far fetched, replenishing the world's phosphorus supply is as easy as taking a leak. You gotta love that. How long do you think it'll be 'til we can score urine-separating toilets from Ikea?
