Build a compost heap. Make the most of the ammonia. Grow a tomato or something.Let me preface this by saying I am a disgusting human.
I piss in a bottle at work. I fill a half gallon container about 3/4 on an average day. Conservative estimate is 2 gallons of piss a week. I dump it in a small 1 foot by 2 foot patch of dirt every day. That is roughly 100 gallons a year. I deposit a hot tub's worth of piss every 4 years. Not gonna lie, thinking about it that way amuses mget a compost pill. Make use of the ammonium grow a tomato or something.
