The 298x Problem
In my 38 years of walking the catwalks of wastewater treatment plants, I have seen the industry undergo several revolutions. We track our carbon dioxide (CO2) electrical footprints with surgical precision.
But while we watch the front door of carbon, a far more dangerous killer is escaping through the back window of our biology: Nitrous Oxide (N2O). According to the IPCC, Nitrous Oxide has a Global Warming Potential (GWP) approximately 298 times that of CO2.
A tiny biological leak of N2O has a catastrophic atmospheric multiplier effect.
A small fugitive leak of N2O can represent up to 80% of an entire plant's climate impact.
From Bioremediation to Bio-Pollution
When Biological Nutrient Removal (BNR) "stalls"—which happens more frequently than operators care to admit—it strips off oxygen too early and releases Nitrous Oxide (N2O) straight into the atmosphere.
