There is a wealth of energy and nutrients in wastewater. New processes enable the recovery of these resources from wastewater and sewage sludge, with the goal of redefining the function of the wastewater-treatment plants. Formerly energy users, they will become energy producers and the source of valuable fertilizer. This new technology has convinced the Swiss Climate Cent Foundation. It is contributing financial support to the construction of the new installation in the ARA Altenrhein. Read more

Faced with polluted river water, rural communities or aid agencies often drill groundwater wells to obtain water supplies. But data collected systematically for the first time in the Amazon basin show that this “solution” can create new problems: the groundwater may contain elevated concentrations of arsenic, manganese and aluminium – up to 70 times over the recommended limit in the case of arsenic, and up to 15 times for manganese.
