A group of scientists and engineers within EU-funded project named OptimEDAR have developed equipment that could be improve the efficiency of waste water treatment plants. This system would enable plants to cut energy use by up to 25 percent, while increasing nutrient removal by up to 20 percent.  After conducting more tests, researchers hope that… »

Collaboration between researchers at the University of California Santa Cruz (UCSC) and researchers at Lawrence Livermore National Laboratory (LLNL) resulted in development of a solar-microbial device that produces hydrogen gas and electricity using sunlight and wastewater as the only energy sources. By combining solar and microbial technology, it provides a sustainable energy source while improving… »
