Mapal Energy, an Israeli start-up which develops and supplies advanced diffusers for wastewater purification plants, has completed a project in Brazil for the supply and installation of floating fine-bubble aeration units in the FLORES WWTP, state of São Paulo. Mapal’s units replaced the existing mechanical aerators, and provide 50% in energy savings while maintaining the quality of (more…)

With policymakers and political leaders increasingly unable to control global climate change, more scientists are considering the use of other engineering approaches other than control at the source to reduce warming impact. The problem is whatever you do, it will have some impact somewhere and somehow. The impact may be good but it also may be bad. University of Iowa (more…)

Researchers at the University of California, San Diego have developed a network of smartphone-based air pollution monitors that allow individuals to track pollution levels in real time and feed a central database of air quality trends citywide throughout the day.

The so-called CitySense devices are equipped with sensors that measure ozone, nitrogen dioxide, and (more…)

NOx is a pollutant that comes from all combustion emissions. It can be minimized but not eliminated at the stack. Painted surfaces (a very common urban surface area) with photo-catalytic characteristics may be able to clean the air of nitrogen oxides and other health-endangering substances. Using a new testing procedure, Fraunhofer researchers can find out how (more…)

Climate change is causing plant and animal species across the U.S. to shift their geographic ranges and life events — from flowering to migration — are being transformed at a faster rate than observed even a few years ago, a new analysis by 60 scientists says.

According to the report, “Climate Change on (more…)

Coal could rival oil as the world’s largest energy source within five years as consumption continues to climb in most regions of the world, a trend that could have profound effects on the climate, the International Energy Agency (IEA) says.

While coal consumption is expected to decline in the (more…)

Every now and then, an exciting opportunity to experience the world comes by and you just have to say what the heck and toss your hat in the ring. If you are interested in sustainability and in particular the so-called water energy nexus, the opportunity of a lifetime is here.

The Abu Dhabi Sustainability Week, taking place (more…)

“Israel has some of the largest and most innovative water projects in the world,” said Peter Tunnicliffe, Executive VP Global Market Development at CDM Smith. Tunnicliffe spoke as part of a delegation of over 40 heads of water solution companies, investors and government representatives who are in Israel this week, meeting with Israeli start-up companies and (more…)

The award-winning environmental film directed by James Balog opens today in the UK. Balog was skeptic about climate change but through his Extreme Ice Survey for National Geographic, he changes his mind in the face of undeniable evidence.

The director makes use of time-lapse cameras to (more…)

A U.S.-based company has developed a sophisticated sensing technology capable of detecting and pinpointing the source of even minor natural gas leaks from great distances, an innovation that could provide critical insights into the still largely unknown climate (more…)
