This book, Liquid Gold: The Lore and Logic of Using Urine to Grow Plants, by Carol Steinfeld explains how urine can be utilized as a resource! Urine contains most of the nutrients in domestic wastewater and usually carries no disease risk.
Starting with a short history of urine use — from ritual to medicinal to even culinary — Liquid Gold shows how urine is used worldwide to grow food and landscapes, while protecting the environment, saving its users the cost of fertilizer, and connecting people to the nutrient cycles that sustain them.
