“…Little information exists regarding the role that sewers play in the production and emission of N 2 O (among others, Koh and Shaw, 2016). Contrary to the current international guidance of the Intergovernmental Panel on Climate Change, gravity sewer systems have recently been found to serve as a source of N 2 O (Short et al, 2014).…”

As sources of greenhouse gas (GHG) emissions, integrated urban drainage systems (IUDSs) (i.e., sewer systems, wastewater treatment plants and receiving water bodies) contribute to climate change. This paper, produced by the International Working Group on Data and Models, which works under the IWA/IAHR Joint Committee on Urban Drainage, reviews the state-of-the-art and modelling tools developed recently to understand and manage GHG emissions from IUDS. Further, open problems and research gaps are discussed and a framework for handling GHG emissions from IUDSs is presented. The literature review reveals that there is a need to strengthen already available mathematical models for IUDS to take GHG into account.

“…Although I – is a common pollutant in water environment, more efficient and environmentally friendly redox mediators are still to be explored. Our system may preferably be used for treatment of various sulfide-containing waste gases, including natural gas, oil refinery waste gas, and anaerobic biogases. , It may also find application in sulfide-rich aquatic environments (e.g., marine sediment) for in situ remediation, which warrants future investigations.…”

Hydrogen sulfide (H 2 S) is a hazardous contaminant in many industrial gases and wastewaters and a potential source of sulfur to be recovered, but effective and sustainable recovery technologies are still lacking. Here, we report a novel photoelectrochemical process for synchronous sulfur recovery and removal of organic pollutant, which typically coexist in waste streams, by using solar-simulating light as the sole driving force. In this system, sulfide was selectively converted into high-purity elemental sulfur (S 0 ) particles at the photoanode, whereas efficient electrochemical oxidation of carbamazepine occurred at the cathode through Fe 2+ /Fe 3+ -mediated peroxymonosulfate activation. The formed sulfur particles with initial sizes of below one micrometer gradually grew into larger particles. Iodine ions were used as anodic redox mediator to favor a selective S 0 production in the solution over the formation of sulfite/sulfate at the electrode surface. The practical feasibility of this system was demonstrated by using carbamazepine-spiked lake water samples. Our work suggests a great opportunity for sustainable recovery of sulfur resource with concomitant benefits of pollutant control by using the inexhaustible solar energy.
