Description

Shenghao Ji and colleagues explain why a wastewater reactor releases more nitrous oxide as its feed ratio shifts, in a 2026 study. Partial nitritation is a step in low-energy nitrogen removal, yet it can emit nitrous oxide, a potent greenhouse gas. The reactor treated food waste digestate with fluctuating composition.

As the ratio of degradable carbon to ammonium rose modestly, the nitrous oxide emission factor climbed eightfold. Keeping the process stable required stronger ammonia oxidation, which fed more electrons toward nitrite reduction. Stronger aeration also stripped more gas out of the liquid. Gene patterns shifted toward nitrous oxide producers over reducers. The authors weigh all three routes as joint drivers of the increase.
