Asia Pacific's waste disposal a burning question

As waste-to-energy incinerators—a mainstay of garbage disposal in economically advanced countries—find their way into the developing countries of the Asia Pacific, questions are being asked about their suitability for ...

Using soap to remove micropollutants from water

Imagine millions of soapy sponges the size of human cells that can clean water by soaking up contaminants. This simplistic model is used to describe technology that MIT chemical engineers have recently developed to remove ...

New catalyst for lower carbon dioxide emissions

If the CO2 content of the atmosphere is not to increase any further, carbon dioxide must be converted into something else. However, as CO2 is a very stable molecule, this can only be done with the help of special catalysts. ...

Study unveils details of how a widely used catalyst splits water

A crystalline compound called ruthenium dioxide is widely used in industrial processes, where it's particularly important for catalyzing a chemical reaction that splits molecules of water and releases oxygen. But the exact ...

Using 60% less water in paper production

An EPFL researcher has developed a mathematical model for optimizing heat transfer in factories and dramatically reducing water and energy consumption. The model could, in theory, cut water use by 60 percent at a Canadian ...
