Transforms waste from water treatment into granular fertilizers. Ostara uses nutrient recovery technologies called Pearl® and WASSTRIP®. This technology transforms recovered nutrients from waste in water treatment processes into granular fertilizers called Crystal Green®. Crystal Green® consists of sustainably recovered phosphorous, nitrogen, and magnesium in one powerful slow-release granule. This fertilizer increases yields with a continuous release and season-long fertilizer supply, prevents soil tie-up for maximized efficiency, and reduces nutrient runoff. Using waste from water treatment extends the life span of raw materials that would have otherwise been converted into waste and disposed in either landfills or water bodies. This process reduces sludge volumes and battles nutrient pollution by removing unwanted phosphorous from waterways.
