WaterEnergyNEXUS: Environmental technologies for the sustainable development
of the water sector
CALL FOR PAPERS
In wastewater treatment plants (WWTPs) the quality of treated water is usually the main issue, while neglecting that the treatment requires a large amount of energy input and that it’s possible to recover valuable resources. According to sustainability policies, there is an urgent need to develop energy-efficient and environmental friendly technologies for WWTPs able to meet the Circular Economy needs.
The novel generation of WWTPs must be able to produce high quality water to reuse and, at the same time, could be a new renewable source of energy and materials. WWTPs have recently been considered as novel bio-refineries. Wastewater is a potential bioenergy source since it contains an internal energy which can be extracted by bacteria and used for renewable energy production. At the same time wastewater is a possible alternative source of several materials eg. Nutrients, Biofuels and Bioplastics.
In this thematic issue, we would like to bring together papers from multiple disciplines on the state-of-the-art of emerging/innovative environmental technologies for the sustainable development of the water sector including principles for wastewater treatment, greenhouse gases, emission control, energy saving/production, and recovery of resources.
