A low-cost, easy-to-use, hand-held device that can determine if the water is safe to drink within minutes has been recently developed at Northwestern University. Using powerful and programmable genetic networks, this new device is able to mimic electronic circuits and thereby perform a range of logic functions, for example, processing an analog input (contaminants) and generating a digital output (a visual signal to inform the user). The research was published in the journal .

Green fuel: the conversion of CO₂ from municipal waste. Image courtesy of Veolia

An interdisciplinary consortium of LIPOR (Intermunicipal Waste Management of Greater Porto), P2X Europe and Veolia is launching feasibility studies at the Maia Energy Recovery Plant to produce green synthetic eFuel made of CO₂ from municipal waste. Up to 100,000 tons of biogenic CO₂ can be captured and recycled for conversion into eFuels in its first phase. This innovative technology will facilitate the conversion of waste into resourses and reduction of GHG emission.

Covering water bodies with solar panels can provide multiple benefits. Project Nexus is a pilot project that responds to the challenges of the energy, water and food nexus in the State of California. The deployment of solar PV panels over water canals reduces the evaporation of water and contributes to the generation of renewable electricity. A win-win game for water, energy and climate!

Atmospheric water harvesting (AWH) is one of the promising solutions for freshwater production. A team of researchers from the University of Texas, Austin, have developed a novel 鈥渟alt-friendly鈥� polyzwitterionic hydrogel that can efficiently harvest large amounts of freshwater from dry air. The study, published in the journal听, shows that the basis for the new hydrogel was a polymer constructed from zwitterionic molecules. Hygroscopic salt combined with hydrogel can capture moisture and enhance swelling, leading to enhanced moisture uptake capacity.听听

Aeration is one of the most energy-intensive processes in water and wastewater treatment and can be costly. To improve the aeration efficiency and cost-effectiveness, researchers from Wetsus have discovered a method of dissolving oxygen into water using a nature-inspired vortex, or whirlpool, that is five times more rapid and much cheaper than the conventional oxygen distribution process using bubble diffusers. The patented method published in the journal听 shows that geometrically constrained vortices in a hyperbolic funnel are a promising aeration technique. 听
