Ostara Nutrient Recovery Technologies Inc. is commercializing proprietary technologies that recover resources from wastewater and recycle them into valuable products.

Ostara's lead technology platform, developed at the University of British Columbia, 1) recovers polluting nutrients, such as phosphorus and ammonia, from sewage sludge liquids that would otherwise be released into the environment, 2) helps wastewater treatment plants reduce operating costs and increase throughput capacity, and 3) provides municipalities and companies with revenue from the sale of the recovered pollutants that are recycled into environmentally safe slow-release fertilizer, under the product name Crystal Green®.

The Ostara technology is deployed in a specialized treatment plant that is integrated into municipal wastewater treatment systems.

Ostara has made significant progress since the Company was founded in 2005:

  • The Company’s first commercial scale plant began operating in Edmonton, Alberta, in May 2007.
  • The first Crystal Green® fertilizer for commercial distribution is being produced from the Edmonton plant.
  • A pilot project at the Hampton Roads Sanitation District’s Nansemond wastewater treatment plant in Suffolk, Virginia, successfully completed trials in March 2007
  • A pilot project began trials in May 2007 at Clean Water Service’s Durham advanced wastewater treatment facility in Tigard, Oregon, in suburban Portland.

According to the 2005 United Nations Millennium Ecosystem Assessment, the increasing accumulation and discharge of nutrients, such as phosphorus, is a significant environmental challenge. Ostara’s proprietary solution to this environmental challenge offers the Company access to a multi-billion dollar global market. The Company estimates that approximately 400 plants in North America and 500 plants in Europe are candidates for the Ostara technology.

Ostara is a VantagePoint cleantech portfolio company.

Ostara is one of the GoingGreen 2009 top 100 private companies.
