Bioelectronics and Green Electronics for a clean Environment
(Corresponding) Ravariu C., Topor A., Mihaiescu D., Manea E.
Topic:
Electric and electronic waste
Some directions of environmental tasks for Romania in collaboration with foreign partners for next decade are: (i) electric and electronic wastes recycling using sustainable future networks suppliers-materials conversion-production, in a chain of countries; (ii) strategies at group of countries...Read more

Nutrients recovery from anaerobic digestion effluent for the production of microalgae biomass
(Corresponding) Psachoulia P., Schortsianiti S., Dergiade I., Chatzidoukas C., Samaras P.
Topic:
Wastewater treatment
The efficient management of anaerobic digestion effluents (ADEs) from biogas plants has raised increasing environmental concerns, as a result of their high content in nutrients, mostly in the form of NH4- and PO4-. Their discharge to farmlands is restricted due to irrigation guidelines, while...Read more
Artificial Neural Network (ANNs) for predicting petroleum hydrocarbons from heavy metals contaminated soils around fuel stations
(Corresponding) Bonelli M., Manni A., Saviano G.
Topic:
Environmental data analysis and modelling
Petrol stations are classified as a dangerous source of pollution for the human population due to the toxicity of emissions from evaporated vehicle fuels and fuel spillages. The contaminants released in the environment are mainly complex mixtures of petroleum hydrocarbon compounds (PHCs) and heavy...Read more

Green sonochemical route for the synthesis of MOFs for the electrochemical reduction of CO2
(Corresponding) VAITSIS C., KANELLOU E., PANDIS P., SOURKOUNI G., ZORPAS A., (Corresponding) ARGIRUSIS C.
Topic:
Gas emissions control and utilization
A zinc-based MOF has been prepared by utilizing adipic acid as an aliphatic ditopic linker via both solvothermal and sonochemical methods. The ultrasound irradiation has reduced the reaction time and has led to smaller particle size. The samples were evaluated for their catalytic efficiency by the...Read more
Development of a non-target screening workflow for the evaluation of micropollutants fate during oxidation processes
(Corresponding) Huynh N., Le Roux J., Guyot J., Moilleron R.
Topic:
Emerging pollutants
Non-target screening (NTS) is of great interest for environmental monitoring because it enables the screening of numerous pollutants, including unknown products. However, methods to identify unknowns are still time-consuming and only deal with a limited portion of the signal. The objective of this...Read more
Toxicity study of Norfloxacin degradation by advanced oxidative process
Costa B., Cordeiro S., Schweizer Y., Weber A., Haas P., de Oliveira L., Ethur E., (Corresponding) Hoehne L.
Topic:
Advanced oxidation processes
Advanced oxidative processes (AOPs) are promising techniques that have been developed to treat and remove these organic contaminants in surface waters and effluents. The objective of this work was to evaluate the toxicity of products generated from UV/H2O2 degradation of solutions containing 5 µg/...Read more
Evaluation of Pressure-Driven Membrane Processes for Nutrients Recovery from Dilute Effluents
Tsaridou C., Karanasiou A., (Corresponding) Plakas K., Karabelas A.
Topic:
Circular economy and industrial symbiosis
Results are presented from an ongoing R&D project, aiming at full utilization of dairy-industry effluents. Development of a membrane-based method is pursued, for treatment of digestate (after fermentation yielding bio-gas) to recover nutrients (N-NH4, P-PO4) and water for reuse/recycling or...Read more
Keywords:
nanofiltration, ultra-low-pressure reverse osmosis, dairy industry effluents, anaerobic digestate, ammonium and phosphorous recovery
Degradation of refractory compounds in industrial wastewaters by advanced technologies based on electrochemical and photochemical oxidation
Petsi P., Sarasidis V., (Corresponding) Plakas K., Karabelas A.
Topic:
Advanced oxidation processes
Results are presented of a systematic experimental investigation aiming to eliminate refractory organics from industrial effluents, of high and non-biodegradable organic load, by two Advanced Oxidation Processes (AOPs). Bench scale experiments were performed with real wastewater samples collected...Read more
Development of efficient techniques for the removal of brominated flame retardants from polymer blends with composition that simulates WEEE
(Corresponding) Charitopoulou M., Papadopoulou L., Achilias D.
Topic:
Electric and electronic waste
Waste electric and electronic equipment (WEEE) has increased enormously because of the rapid expansion and consumption of electronic devices and their short lifespan. Recycling of WEEE is challenging, due to the presence of various materials including glass, metals and plastics (Buekens and Yang...Read more
How to estimate biocide mass loads in urban water discharges and their impact on the river contamination?
(Corresponding) BRESSY A., PAIJENS C., TEDOLDI D., FRERE B., MAILLER R., ROCHER V., MOILLERON R.
Topic:
Emerging pollutants
Biocidal substances are ubiquitous in urban areas; they are used as preservatives in daily products, building materials, and as domestic pesticides. Despite these facts, urban sources of biocides, contrary to agricultural inputs, have been overlooked in terms of environmental risk assessment. The...Read more
