A system to produce low-cost fertilizer
The Struvite project aims at implementing a system to produce low-cost fertilizer, based on the collection of precipitate rich in phosphorus and obtained from the blending of urine with an adequate amount of magnesium mineral.
The key point of the project is economic sustainability once in use: buying the necessary magnesium mineral thanks to the profits earned from the selling of the fertilizer and/or of waste products, such as ammonia.
The Struvite project follows the example of STUN project, implemented by the Swiss research institute EAWAG in Nepal, especially by its SANDEC department.
The project includes an initial collection of information (such as the amount of urine produced by a human being per day), a research in websites and in literature about the assessment of the market value of struvite, a collection of technical material, especially documents published by SANDEC and a revision and a translation of a spreadsheet created by SANDEC for the evaluation of the output based on the type of magnesium mineral used.
