The aim of this study is to model and optimize a district energy system using the city of Geneva as a model. This will be done by using Energy Integration techniques together with efficient actions leading to CO2 emission reductions. This will be done usin ...
Atmospheric emissions of gas and particulate matter from a large ocean-going container vessel were sampled as it slowed and switched from high-sulfur to low-sulfur fuel as it transited into regulated coastal waters of California. Reduction in emission fact ...
Living bacteria offer an ecological and cost-effective alternative to the classical physical and chemical techniques for the treatment of environmental contaminations. Although their increasing use in toxic metal removal, systematic studies on the influenc ...
The aim of this study was to characterize hospital effluents in investigating the CHUV importance as source of pollutants, the range and amounts of pharmaceuticals that are used in the hospital and the need of source treatment of the hospital sewage. The C ...
Rainwater harvesting is a practice already widely used throughout rural New-Zealand, which makes it well developed on the country’s market as well as in people’s minds. Therefore, it is pertinent to study whether this sustainable practice could be implemen ...
Human urine has the potential to be a sustainable, locally and continuously available source of nutrients for agriculture. Phosphate can be efficiently recovered from human urine in the form of the mineral struvite (MgNH4PO4•6H2O). However, struvite format ...
More than 8.5 million people live in the urban area of Bogotá and more than 1.4 million vehicles are taking the road every day. Air pollution is becoming more and more of a problem. Today, air pollution related respiratory diseases are the main cause of de ...
The present study takes place in Ouagadougou (Burkina Faso), a typical Sub-Saharan city where water shortage and food crisis necessitate wastewater reuse in urban agriculture. Different issues linked to this practice were studied in two components separate ...
Urine source separation (NoMix technology) is a promising innovation in wastewater management. To improve and further develop NoMix technology, it has been implemented in four Swiss households and at our research institute (Eawag). We conducted measurement ...
Recent studies have shown that electrolysis can be an efficient process for nitrogen removal from urine. These studies have been conducted with urea solutions or fresh urine, but urine collected in NoMix toilets and urinals has a substantially different co ...
