Ostara

What Ostara does

Ostara Nutrient Recovery Technologies Inc., founded in 2005 and headquartered in Vancouver, Canada, develops and commercializes proprietary nutrient recovery technology that extracts phosphorus and nitrogen from municipal, industrial, and agricultural wastewater streams and converts them into high-efficiency phosphate fertilizers sold under the Crystal Green and CG P2X brands. The company's core technology is the Pearl fluidized bed reactor system, often deployed alongside WASSTRIP, which crystallizes magnesium-ammonium-phosphate (struvite) from wastewater into a granular fertilizer product. Ostara operates 22 full-scale nutrient recovery facilities globally and manufactures fertilizer at facilities in St. Louis, Missouri (targeted at 200,000 tons of Crystal Green annually, approximately 10x prior aggregate capacity), Tampa, Florida, and Fort Meade, Florida. The flagship product, CG P2X (9-42-0 with 9 Mg), uses a root-activated nutrient release mechanism that responds to plant demand and is positioned as a premium alternative to conventional phosphate fertilizers (MAP, DAP, NPS, TSP), with claimed 40% reduction in application rates and over 2X plant-available nutrients.

The company serves two interrelated customer segments. Municipal water utilities deploy Pearl reactors under design-build or operating lease arrangements and enter long-term fertilizer offtake agreements with Ostara; named installations include the City of Edmonton's Gold Bar plant, City of Atlanta's R.M. Clayton, Irish Water's Ringsend, Clean Water Services Durham, and Hias IKS in Norway. Agricultural growers are reached through a network of 70+ retailers across North America and Europe, plus exclusive regional distribution partners (Taurus Agricultural Marketing in Western Canada, ICL Specialty Fertilizers across UK/EU/Nordics/Australia/NZ, and Evoqua Water Technologies for North American and Western European municipal markets). Pricing is quote-based under multi-year contracts; revenue is generated through hardware/equipment sales (Pearl reactor deployment), long-term fertilizer offtake agreements, and product sales via distribution channels.

Ostara is privately held and has been wholly owned by Wheatsheaf Group Limited, the food and agriculture investment arm of the UK-based Grosvenor Estate, since an all-cash acquisition in July 2020. The company has raised approximately $145M+ in disclosed equity capital across multiple rounds spanning 2008-2022, including a $70M Series C in October 2022, and received a $7.6M USDA grant in 2023. Recent leadership changes include CEO Tom Snipes (appointed February 2025), VP Agronomy Michael Howell (appointed May 2026), and CTO Dr. Aaron Waltz, signaling continued organizational build-out around commercial scale-up.

Revenue model

1. Fertilizer Product Sales: Ostara manufactures and sells high-efficiency phosphate fertilizers (CG P2X, Crystal Green, CG Pearl) through a network of established retailers and distributors in North America and Europe. Products are sold to farmers, agricultural operations, and turf & ornamental markets.
2. Nutrient Recovery Technology Licensing/Deployment: Ostara deploys its Pearl nutrient recovery systems at municipal and industrial wastewater facilities under various partnership models (design-build agreements, operating lease models), generating revenue through technology deployment and fertilizer offtake agreements.
3. Fertilizer Offtake Agreements: Municipalities and utilities operate Ostara's Pearl reactors to produce Crystal Green fertilizer, which Ostara purchases under long-term offtake agreements for resale through its distribution network. This generates revenue streams for both Ostara and the facilities.
