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

Wastewater valorisation, energy recovery, urea, adsorption, circular economy.
Interannual large-scale variability in the Eastern Mediterranean Sea and interactions with the Aegean Sea
(Corresponding) Velaoras D.
Topic:
Climpact: national network for climate change and its impacts
The Mediterranean Sea and its eastern sub-basin are marginal oceanic basins subjected to strong anthropogenic and natural pressures. During the last decades new findings have revised the way of assessing the circulation and physical functioning of the eastern Mediterranean Sea. Natural oscillations...Read more
Contribution to low-carbon building industry and improved durability through incorporation of waste into cement composites
Estokova A., (Corresponding) Figmig R., (Corresponding) Singovszka E.
Topic:
Solid waste management
By using mineral waste in the production of cement composites, it is possible not only to reduce greenhouse gas emissions and carbon footprint, but by adding secondary waste such as fly ash, silica fume or slag, some properties of the resulting composites are also improved. The waste mentioned are...Read more
Regeneration of dissolved Fe(II) from Fenton sludge at a microbial fuel cell using a novel biocathode
(Corresponding) Wang G., Tang K., Jiang Y., Andersen H., Zhang Y.
Topic:
Advanced oxidation processes
Fenton reactions are widely applied for degrading recalcitrant pollutants, but the resulting ferric sludge remains a challenge. A novel concept for regenerating Fe(II) solution at pH 6 from ferric sludge generated in neutral Fenton is proposed. A microbial fuel cell (MFC) with biocathode and...Read more

Topic:
Disaster risk reduction and management
The present paper provides an integrated framework for modelling of coastal inundation, aiming to help coastal communities understand their risks and consequently to prevent the adverse effects to society. The proposed framework involves the implementation and coupling of a suite of sea state...Read more
Alternatives for removing fluoride from water for human consumption and water for reuse
(Corresponding) Nigri E., Santos A., (Corresponding) Rocha S.
Topic:
Water and wastewater reuse
This compilation aims to describe the studies carried out focusing on the treatment of 100-127 mg/L of wastewaters involving different fluoride removal alternatives which demonstrated efficacy. Adsorption by bone char, both in batch as in continuous systems, including chemical and thermal...Read more
Keywords:
Bone char; Fluoride removal; Adsorption; Electrocoagulation; Precipitation
New solutions for a better and sustainable agriculture
The emergence of the bioeconomy and the concept of sustainability in production processes have been essential for the protection of the environment and biodiversity, as well as for the implementation of processes for energy recovery, the creation of new jobs and increased competitiveness...Read more

Incorporation of negatively charged MWCNT-fGO self-assembled nanomaterials into PLA polymeric membranes for wastewater treatment
(Corresponding) Khalil H., Nassar L., Wadi V., Naddeo V., Banat F., (Corresponding) Hasan S.
Topic:
Wastewater treatment
The incorporation of nanomaterials in membrane’s matrix aims mainly to improve the properties of the membranes such as hydrophilicity, mechanical strength, thermal stability, water flux. Multi-walled carbon nanotubes (MWCNT) and functionalized graphene oxide (fGO) have recently attracted attention...Read more
Assessing the performance of green nano Zero Valent Iron in column experiments for the removal of NSAIDs from water
(Corresponding) Panagou I., Kalli M., Noutsopoulos C., Mamais D., Koumaki E., Malamis S.
Topic:
Emerging pollutants
The existence of emerging contaminants in the aquatic environment is globally a major concern. Among them, non-steroidal anti-inflammatory drugs (NSAIDs) are a vast category of pharmaceuticals that are widely consumed and cannot be completely removed in typical wastewater treatment systems, thus...Read more
Keywords:
nano zero valent iron, green synthesis, continuous flow experiments, NSAIDs, emerging contaminants
Methane distribution over Greece as derived from Sentinel-5P TROPOMI data
EVANGELOU I., GIALESAKIS N., DASKALAKIS N., (Corresponding) KANAKIDOU M.
Topic:
Climpact: national network for climate change and its impacts
Global warming, induced mainly by greenhouse gases emitted by human activities, is an environmental issue of crucial importance for society. Greenhouse gases, such as methane (CH4), need to be monitored and their anthropogenic emissions quantified in order to be reduced. We here present, the first...Read more
