Professor Brian Cantwell, graduate student Yaniv Scherson, Professor Craig Criddle, and graduate students George Wells and Koshlan Mayer-Blackwell in the Criddle lab with the nitrous oxide decomposition cell.Within the sludge of wastewater treatment plants is an invisible world teeming with microbes. Here, diverse species of bacteria convert solid and liquid wastes into gases, some of which contribute to global warming. Two Stanford University engineers are developing a new sewage treatment process that would actually increase the production of nitrous oxide (“laughing gas”)… »
