For the production of struvite, firstly urine is needed. This can be collected from markets, urinals, public buildings. It must be separated from other sanitation products using [[Urine Diverting Dry Toilet|urine diverting toilets]] or other EcoSan technologies. Then magnesium must be obtained. This can come from bittern from salt production, which contains 3-10% magnesium, or magnesium sulphate from fertilizer powder, containing 5-10% magnesium.
