Ostara Aims to Stave Off Peak Phosphorous.Forget peak oil. The next big crisis is peak phosphorous–a shortage of mined phosphorous for fertilizer. The problem is so bad that supply won’t be able to meet agricultural demand within the next 30 to 40 years. But a Robert F. Kennedy Jr.-backed startup called Ostara thinks it might have the solution: a system that removes nutrients–including phosphorous–from wastewater and turns it into a slow-release commercial fertilizer called Crystal Green. The company’s second commercial facility was unveiled this week at the Nansemond Treatment Plant in Suffolk, Virginia.
Ostara’s process features a reactor that processes sludge liquid and recovers nutrients that might otherwise have to be disposed of using costly processes. The reactor is so effective that it can extract over 90% of phosphorous from a municipal waste stream. “Our process works very much in complement to existing wastewater treatment technology. There are plants that have advanced processes to remove nutrients from raw sewage, but they need to dispose of them. We can take those concentrated nutrient flows and extract out nutrients,” explains Phillip Abrary, the CEO of Ostara, in an interview with FastCompany.com. “The system pays back for itself in five years.”
