Researchers are exploring how to manipulate bacterial communication, known as quorum sensing, to reduce the carbon footprint of wastewater treatment plants. By tuning these microbial signals, plants can significantly cut nitrous oxide emissions and reduce the electricity needed for aeration. This approach focuses on improving the efficiency of microbes to create granular sludge and enhance methane production. These optimizations could transform wastewater facilities from energy-intensive cost centers into energy-producing power stations.
