Ostara

Ostara Nutrient Recovery Technologies 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 fertiliser, Crystal Green®. The process greatly reduces nutrient management costs and helps plants meet increasingly stringent discharge limits while improving operating reliability.  Crystal Green is marketed through a global network of blenders and distributors to growers in the turf, horticultural and agriculture sectors. Its unique plant-activated mode of action improves crop yields, enhances turf performance and significantly reduces the risk of leaching and runoff, thus protecting local waterways from the nutrient pollution.

Ostara operates multiple facilities throughout North America and Europe and recently partnered with the City of Chicago to build what will be the largest municipal nutrient recovery facility in the world when launched in 2015. The company is the recipient of numerous awards including a World Economic Forum 2011 Technology Pioneer, the Global Cleantech 100 and Deloitte’s Technology Green 15.
