May 11, 2012, Vancouver – A successful public/private partnership in sustainable technology continues between Clean Water Services and Ostara Nutrient Recovery Technologies Inc. with the unveiling earlier this week of the world’s largest municipal Nutrient Recovery Facility at the Rock Creek Advanced Wastewater Treatment Facility in Hillsboro, Oregon.
 
Clean Water Services’ Rock Creek Nutrient Recovery Facility uses Ostara’s Pearl® Nutrient Recovery Process to capture phosphorus and nitrogen from wastewater and transform them into Crystal Green®, an environmentally friendly, slow-release fertilizer, which is sold locally and throughout the country.
 
Ostara’s Pearl process benefits Clean Water Services and its ratepayers by reducing operations and maintenance costs, increasing plant capacity and providing revenue from the sale of the fertilizer. The combination of cost savings and revenue are projected to pay off the $4.5-million Rock Creek Nutrient Recovery Facility in six years.

The Rock Creek Nutrient Recovery Facility requires one-seventh the amount of energy to create 1,200 tons of Crystal Green as it takes to create an equal amount of conventional fertilizer.
 
Clean Water Services is now the largest municipal producer of Crystal Green in the world. Crystal Green produced at the facility will be used in nurseries, lawn landscape, and turf applications throughout the Willamette Valley and the state of Oregon, as well as throughout North America.

OSTARA'S CANADIAN ROOTS
Ostara is a clean water company that provides phosphorus management solutions to municipalities, industry and farmers. The company was founded in 2005 when it licensed the nutrient recovery technology from the University of British Columbia to develop and market the wastewater treatment process and the revenue-generating fertilizer.

The proprietary technology, called Pearl®, recovers otherwise polluting nutrients, phosphorus and nitrogen, from wastewater streams at treatment facilities, helping plants reduce costs and meet nutrient discharge limits. The nutrients harvested from these wastewaters are transformed into a fertilizer product marketed as Crystal Green®, an environmentally responsible source of phosphorus fertilizer.
