Could be human urine used as a fertilizer for seedbed vegetable?
This is not surprising if still more frequent efforts are appearing to use domestic liquid waste as a fertilizer in gardens and fields. One such a possibility is the urine. The average adult is capable of producing annually about 500 liters of this liquid. The slurry as a fertilizer is distributed and dissipated after land completely normally in the modern agriculture. However, the certain problem is also that most people are unable to break away from the idea that this liquid is something impure, or even harmful.
Zeolite adsorbent media directly in the household
Probably the main disadvantage of conventional repair systems of our homes is their linear nature. All types of waste water are mixed and cleaned at the end of the waste piping. Each functioning household produces yellow water (urine), brown water (faeces) and grey water (shower, washing machine). Some valuable sources of plant nutrients as possible fertilizers are mixed with other pollutants. A small amount of nutrients from domestic wastewater is mixed with a lot of the other waters and rain precipitations.
Some research institutions (especially in Finland and Sweden) are shown case studies and pilot projects studying in more appropriate ways how to use liquid household waste as a fertilizer. The unique physicochemical properties of the zeolite are used in these studies. Natural zeolite is known and important adsorbent material for the treatment of waste water. Due to its structural properties zeolite is able to very effectively adsorb ammonium ion and heavy metal ions from aqueous solution
ECOSAN systems and zeolite
Over the last two decades the efforts are appearing to address these issues in a sustainable manner. Ecological sanitation home systems (ECOSAN) allow complete recovery of all nutrients in the faeces, urine and grey water. On behalf of agriculture and minimizing water pollution. Not just as a fertilizer. These same systems allow efficient water use and maximum reuse, particularly for irrigation. Well known are the results of the case study of University of Gothenburgh (Dept. of Plant and Environmental Sciences), which as one of the possible adsorption and separation media was using just natural zeolite. It is certain that the zeolite is one of ecological materials of the future.
