Seasonal variation of the biochemical methane potential of fruit and vegetable wastes produced in the Mediterranean area
Kalogiannis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic:
Food waste
Fruit and vegetable wastes produced massively in open markets are a suitable feedstock for biogas production and digestate of high fertilizing value. A first step of designing anaerobic digestion systems for treating these wastes efficiently is to study the impact of the seasonal variation on the...Read more

Spyridonidis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic:
Environmental biotechnology and bioenergy
The biological upgrade of biogas to biomethane (CH4 > 90%) is a popular emerging technology, since the produced CO2 is not removed but is converted to biomethane using hydrogen (H2). The initial aim of the present study is the acclimatization of a microbial population derived from a typical...Read more

Degradation of cytostatic drugs in water by ozonation
(Corresponding) Garcia-Costa A., Gouveia T., Pereira M., Silva A., Alves A., Madeira L., Santos M.
Topic:
Advanced oxidation processes
This work presents the degradation of five cytostatics found in Portuguese WWTP effluents: bicalutamide (BICA), capecitabine (CAP), cyclophosphamide (CYC), ifosfamide (IFO) and mycophenolic acid (MPA) using non-catalytic ozonation. Experiments were performed with 1 µM of each cytostatic at pH: 7.3...Read more

Is Greece greener than the data shows? Calculation of Green GDP and comparison with neighboring countries
(Corresponding) Stjepanović S., Škare M., Tomić D.
Topic:
Environmental data analysis and modelling
Is Greece greener than the current economic indicators show? GDP is used as the leading economic indicator of economic growth and progress. GDP as a measure, among other things, lacks an environmental component. In this paper, we have developed a Green GDP for Greece and neighboring countries and...Read more

Chemical weathering rates and CO2 consumption in the Savuto basin (Sila Massif, Italy) inferred from riverine water chemistry
(Corresponding) Fuoco I., De Rosa R., Timpano A., Cundari F., Apollaro C.
Topic:
River systems in diverse climates and environments
The aim of this work was to estimate the silicates (SWR) and carbonates (CWR) weathering rates as well as the CO2 consumption in the Savuto basin (Sila Massif, Southern Italy), studying the riverine water chemistry. Six sampling sites were investigated. Starting from the rain composition,...Read more

Preliminary study on fluoride removal from contaminated groundwater by nanofiltration
(Corresponding) Fuoco I., Apollaro C., Criscuoli A., De Rosa R., Figoli A.
Topic:
Water treatment
In this work, a commercial nanofiltration (NF) membrane, named SPR 10113, was used for the first time to treat a real F-contaminated groundwater (F= 8.9 mg/L) coming from deep crystalline aquifer of Calabria Region (Southern Italy), in order to verify its efficiency in terms of fluorine rejection...Read more

Microplastics in marine biota of North Aegean Sea: Summarizing and comparing preliminary findings
Marmara D., Vogiatzis G., Christofidis C., Stamelos A., (Corresponding) Krasakopoulou E.
Topic:
Microplastics in the marine environment
Rising scientific literature and legislation measures have highlighted the concern on plastic pollution and the issue of microplastics. In the context of this study, 3 marine species of commercial interest (bogues, Mediterranean mussels, blue crabs) were examined, concerning microplastics’ presence...Read more
Microalgae bio-fixation efficiency of carbon dioxide through innovative planar photobioreactor
Costantino V., Carone M., (Corresponding) Riggio V., (Corresponding) Derossi C., Alpe D., Occhipinti A., Zanetti M.
Topic:
Climate change mitigation and adaptation
The high anthropogenic activity of recent centuries has led to an urgent need to improve CO2 capture and sequestration technologies. In this context, microalgae systems have gained importance, thanks to their high photosynthetic efficiency and the many applications to which they can be destined...Read more

Comparison of the continuous fermentative hydrogen production efficiency from cheese whey in suspended and attached-biomass growth systems
ALEXANDROPOULOU M., LYBERATOS G., (Corresponding) ANTONOPOULOU G.
Topic:
Wastewater treatment
In the present study, comparison of dark fermentation (DF) efficiency from cheese whey (CW) in an anaerobic UpFlow Column Reactor (AUFCR), filled with a support material for biomass attachment and a Continuous Stirred Tank reactor (CSTR), was assessed. The process efficiency and stability as well...Read more
