Two green-tech startups capture the value of wastewater
By Heather Clancy
Had the good fortune last week to interview individuals from not one but two technology innovators who have developed processes for bringing new value to wastewater.
The first, Ostara, is focused on recovering phosphorous and nitrogen — which have enormous potential value in fertilizers but can be a huge problem when they reach excess levels in bodies of water. The Ostara Pearl process uses separate chemical reactions to recover these nutrients out of wastewater and create a slow-release fertilizer called Crystal Green. I’m simplifying things for the sake of the laypeople among us, including me.
The company’s latest facility was opened at the end of May in Suffolk, Va. Managed in cooperation with the Hampton Roads Sanitation district, the facility will recover nutrients out of the Chesapeake Bay Watershed. Here’s a statement from Ostara’s president and CEO Phillip Abrary:
“Our technology integrates into the treatment system, processes the liquids from the solids recycle streams and recovers phosphorous and other nutrients, and then converts them into a high-quality environmentally friendly commercial fertilizer, increasing operational efficiency for the plant. This approach provides [Hampton Roads] with a cost-effective and environmentally sound operational improvement and also creates a fertilizer product made form the only sustainable source of phosphorous, waste, which is non-leaching and therefore helps protect waterways.”
