In a collaborative process within the Sustainable Sanitation Alliance Working Group 05 on Food Security and Productive Sanitation Systems, the Stockholm Environment Institute (SEI) recently published a “Practical Guidance on the Use of Urine in Crop Production”.
This book gives practical guidance on the use of urine in crop production as a vital component of sustainable crop production and sanitation systems. It also includes guidance on how to start activities that will facilitate the introduction of new fertilizers to the agricultural community. This general sourcebook is for professionals, extension workers and practitioners in the field of agriculture, water and sanitation and should serve as a support tool for the development of locally adapted guideline versions.
The publication is available as a PDF (1.7 MB)
Have you ever used a toilet and got paid afterwards?
A Non-Governmental Organization (NGO) in India has just claimed to be doing this. From January 15th 2008 onwards, users of a local toilet system based on ecological sanitation (ecosan) principles will be paid the sum of 10 paise* for each visit.
By doing this, the Society for Community Organization and Peoples Education (SCOPE) wants to create an awareness for the value of human waste: “urine and faeces are so rich in nutrients for farm production that they are worth buying”.
The first Ecosan Community Compost Toilet in the country in Saliyar Street is functioning for the past 18 months. Every fortnight on an average 250 liters of urine is collected, the same is used for farming purposes. Already the Tamilnadu Agricultural University is studying the use of urine as liquid fertilizer for the past one year, under an MoU signed by SCOPE with the University. WASTE of Netherlands has funded, Rs. 4 lakhs for the two-year research project. (src)
Apparently, this really is the first time anywhere in the world that toilet users are being paid. What a smart approach!
