Topic:
Circular economy and industrial symbiosis
Red mud (RM) is the main residue produced by the alkaline extraction of aluminum from bauxite, and it contains valuable metals (e.g., iron, aluminum, titanium, silicon). Aim of this research was to investigate the biologically induced leaching of valuable elements from RM using autochthonous...Read more

Energy recovery from urea in decentralised wastewater streams
Asiain-Mira R., Zamora P., Rogalla F., Monsalvo V., (Corresponding) Torrente-Murciano L.
Topic:
Water, energy and/or food nexus
This work presents the design of a new process that enables energy recovery from wastewater, based on the selective adsorption of urea from urine and its subsequent decomposition into hydrogen.
Removal of nitrogen compounds is at the core of wastewater treatment, as their uncontrolled discharge...Read more
