Ostara helps protect precious water resources by changing the way cities around the world manage nutrients in wastewater streams. The company's Pearl® technology recovers phosphorus and nitrogen at municipal and industrial wastewater treatment plants and transforms them into a high-value, eco-friendly fertilizer, Crystal Green®.

The process greatly reduces nutrient management costs and helps plants meet increasingly stringent discharge limits while improving operating reliability.

Crystal Green is the first continuous release granular fertilizer to provide Root-Activated™ phosphorus, nitrogen and magnesium (5-28-0-10Mg), and is marketed through a global network of blenders and distributors to growers in the turf, horticultural and agriculture sectors. Its unique Root-Activated™ mode of action improves crop yields, enhances turf performance and significantly reduces the risk of leaching and runoff, thus protecting local waterways from nutrient pollution.

Ostara operates multiple facilities throughout North America and Europe and will open the world's largest nutrient recovery facility in partnership with the City of Chicago in summer 2016.
