Media Alert: Unveiling of New Nutrient Recovery Facility That Will Protect Local Waterways, With Remarks by Governor Edward G. Rendell and Keynote Speaker Robert F. Kennedy, Jr.

Ostara's Nutrient Recovery Facility at the City of York's Wastewater Treatment Plant Will Recover Nutrients From Wastewater to Create an Environmentally-Friendly Fertilizer

The City of York and Ostara Nutrient Recovery Technologies Inc. will officially unveil their new Nutrient Recovery Facility at the York Wastewater Treatment Plant (York WWTP) on September 16. The facility uses Ostara's Pearl® Nutrient Recovery Process to recover nutrients such as phosphorus and ammonia from the York WWTP's wastewater stream to produce an environmentally-friendly, slow-release fertilizer, marketed as Crystal Green®.

The opening ceremony will showcase a unique public/private partnership where Ostara has designed, built and financed the nutrient recovery facility for a monthly treatment fee, which will help York WWTP efficiently meet their nutrient limits and reduce operational costs. These nutrient recovery benefits are provided without the City of York having to make any capital investment in the system. Furthermore, revenues from the sale of Crystal Green fertilizer produced at the plant are shared with the City of York, thereby further improving the economics of the facility.

Ostara's Nutrient Recovery Facility is the second nutrient recovery system of its kind in the nutrient-sensitive Chesapeake Bay Watershed. The first facility opened at Hampton Roads Sanitation District's Nansemond Wastewater Treatment Plant in May 2010.

During a pilot study conducted at the York WWTP in Spring 2008, it was found that the Pearl process recovered more than 90 percent of the phosphorus and 20 percent of the nitrogen that would normally be returned back to the plant from the solids processing.
