VANCOUVER, CA, September 27, 2018 The City of St. Cloud has selected Vancouver-based Ostara to install a nutrient recovery system at their Wastewater Treatment Facility, as part of the City’s Nutrient Recovery and Reuse (NR2) Project.  The $22M Project was partially funded through a $6.6M Point Source Implementation Grant made possible by the Minnesota Clean Water Legacy Act.  The Ostara process is a key part of the project in recovering valuable nutrients such as phosphorus from the wastewater centrate to create a high value, environmentally friendly fertilizer product.

“Ostara’s technology is a key part of the entire NR2 project, and illustrates how St. Cloud is leading the way in sustainability in Minnesota with the implementation of innovative and cost effective technology,” said Patrick Shea, Public Services Director for the City of St. Cloud. “We are excited to see this project begin construction, and are anticipating its completion as early as Spring 2019.”

The NR2 Project also includes installation of biofuel storage to help optimize the fuel produced for the biofuel generator and reduce energy costs; and biosolids reuse which involves expanding the treatment process to produce Class A Biosolids through the Lystek process.

“We are extremely proud to be part of this project,” said Dan Parmar, CEO of Ostara. “In addition to helping protect sensitive waterways such as the Mississippi River from an over-abundance of phosphorus, our technology will provide sustainably produced and locally made, enhanced crop nutrition to local farms in the area.”

Phosphorus is considered a major contributor to nutrient pollution, entering bodies of water from numerous sources including sewage treatment plants.  Phosphorus in waterways cause algae to grow and bloom, creating a toxic condition called eutrophication which destroys aquatic life and limits recreational enjoyment of waterways.

The Mississippi River delta westward to the upper Texas coast is called the Gulf of Mexico dead zone, and has one of the highest levels of eutrophication in the world.  Programs such as the Minnesota Clean Water Legacy Act (CWLA) have ambitious plans to restore water resources to meet state water quality standards and protect them from degradation.

The Ostara nutrient recovery system implemented at the St. Cloud Wastewater Treatment Plant, a biological nutrient removal facility with a 17.9 MGD design flow, will serve a day time population of over 120,000 people in St. Cloud, St. Joseph, Sartell, Sauk Rapids, Waite Park, and St. Augusta. Ostara’s technology will help the St. Cloud Wastewater Treatment Plant increase operational efficiencies through struvite avoidance (a cement like scale in pipes caused by an excess of nutrients) and the recovery of phosphorus using Ostara’s environmentally friendly process. The high value fertilizer – sold as Crystal Green® – will be produced at St. Cloud Wastewater Treatment Plant upon commercial operation in Spring 2019.

Crystal Green will further protect the Mississippi River Basin through its application on local agricultural land as fertilizer. Crystal Green’s unique “Root-Activated™” mode-of-action which releases nutrients according to root demand, improves crop uptake and significantly reduces leaching and runoff into surrounding waterways.

Ostara completed a demonstration project at the St. Cloud Wastewater Treatment Plant in 2014, and through a series of subsequent evaluations Ostara’s nutrient recovery technology was selected as part of the NR2 Project Element, to “recover valuable nutrients from the wastewater centrate.” Selection criteria included qualifications, site visits & installation references, life cycle cost, operations, customer support, safety, and sustainability. Construction of the nutrient recovery facility was commenced in July 2017 and will be completed as early as April 2019.

About Ostara Nutrient Recovery Technologies Inc.:

Ostara 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 fertilizer, Crystal Green®. The process greatly reduces nutrient management costs and helps plants meet increasingly stringent discharge limits while improving operating reliability. Crystal Green is the first continuous release granular fertilizer to provide Root-Activated™ phosphorus, nitrogen and magnesium (5-28-0 with 10%Mg), and is marketed through a global network of blenders and distributors to growers in the turf and agriculture sectors. Its unique Root-Activated™ mode of action improves crop yields, enhances turf performance and significantly reduces leaching and runoff, thus protecting local waterways from nutrient pollution. Ostara operates multiple facilities throughout North America and Europe. For more information, visit www.ostara.com and www.crystalgreen.com.
