About Us

Vancouver-based Ostara helps protect precious water resources by changing the way cities around the world manage excess nutrients both in wastewater streams and due to fertilizer runoff. The company’s nutrient management solutions recover otherwise polluting nutrients, phosphorus and nitrogen, from municipal and industrial water streams, and transforms them into a continuous-release, eco-friendly fertilizer marketed as Crystal Green®.The process helps wastewater treatment plants reduce nutrient management costs, meet increasingly stringent discharge limits and improve operating reliability, while Crystal Green’s innovative Root-Activated™ mode-of-action improves crop yield and performance, while reducing the risk of nutrient leaching and runoff.
