Innovation
Ostara is developing patented, first-of-its-class technology to solve global nutrient challenges and feed the world.
Introducing a New Method to Produce Fertilizer
Ostara was founded in 2005 after developing an innovative method of granulating struvite to repurpose as phosphate fertilizer.
Solving challenges related to struvite buildup in water treatment facilities.
Transforming struvite into our patented Crystal Green® Pearl Crop Driven Release™ fertilizer.
Spearheading Global Adoption of New Technology
We introduced our nutrient recovery technology to cities around the world, removing excess phosphorus from wastewaters and turning it into a saleable fertilizer.
Providing a revenue source for water managers through fertilizer sales.
Now over 25 commercial installations worldwide and counting.
Driving Demand for Sustainable Fertilizer
We built demand for a sustainable and efficient fertilizer product that reduces the amount of phosphorus released into the environment through agriculture.
Demand for the product throughout Canada, U.S., Europe and the U.K. continues to increase as growers seek more sustainable fertilizer options.
Crystal Green Pearl is produced in SGN 90 and SGN 150.
Expanding Production to Meet Demand
Increased interest and limited supply for the Crystal Green Pearl drove Ostara to recreate this innovative product in its own manufacturing facilities.
Developing the first production facility to ever produce granulated struvite ( Crystal Green® fertilizer) in Fort Meade, FL.
Launching an additional facility in St. Louis in 2022 that will produce over 250,000 tons of Crystal Green fertilizer annually.
Crystal Green is available in SGN 300.
