FENTON REAGENT IN COMBINATION WITH UV LIGHT AND ULTRASOUND WAVES APPLIED FOR CAFFEINE OXIDATION
Villota N., Lomas J., Lombraña J., Ferreiro C.
Topic:
Advanced oxidation processes
The oxidation of aqueous caffeine solutions ([Ca]0=100.0 mg L-1) was analyzed, operating at pH=3.0 and 25ºC using different AOPs, which combine the Fenton reagent ([H2O2]0=15.0 mM and [Fe2+]0=20.0 mg L-1) with low power UV light (15W,), medium (150W), and high (720 W). The Fenton reagent, combined...Read more
US/H2O2 combined technology applied to the paracetamol oxidation
Villota N., (Corresponding) Jose L.
Topic:
Advanced oxidation processes
This study analyzes the colour acquired by oxidizing paracetamol aqueous samples through the combined US/H2O2 technology. When operating with only the action of the waves [US]=1.0 kWh/mmol C8H9NO2, the water acquires progressively hue according to a ratio of 0.0004 AU/min, with a degradation output...Read more
Hydrogen production from cotton wastes by mean of dark fermentation
(Corresponding) Sołowski G., Konkol I., Shalaby M., (Corresponding) Cenian A.
Topic:
Energy technologies and sustainability
Dark fermentation of textile wastes is discussed in the paper. In the experiment were used cotton wastes. Before fermentation the cotton was hydrolyzed using 0.1 M of HCl. The inoculum was pretreated using heat shocked for 0.5 h at temperature of 105°C. The fermentation was carried out under...Read more
Elevated CO2 in air changes photosynthetic response of Hordeum vulgare and Bromus secalinus to cadmium pollution in soil
(Corresponding) Januskaitiene I., Diksaityte A.
Topic:
Heavy metals in the environment
The integrated effects of increased atmospheric CO2 and heavy metals pollution may have important implications for plant growth. Elevated atmospheric CO2 can affect plant defences through its significant effects on plant growth. Some studies have found that elevated CO2 can decrease oxidative...Read more
Biosynthesis of Xanthan Gum from Fermenting Potato Peels Extract: Influence of Sucrose Supplementation on Yield and Apparent Viscosity
(Corresponding) Abud A., Silva A.
Topic:
Food waste
Several residues and carbohydrate-rich effluents have been studied as a possible alternative in the substitution or implementation of the traditional cultivation medium of xanthan gum, helping in the management of these residues and, consequently, reducing fermentation costs. This work studied the...Read more
Sustainable Development and Digital Literacy in Educational Practice and Politics. Case study on participative geospatial technologies applications of Greek secondary students
(Corresponding) Exarchou E., Klonari A.
Topic:
Spatial environmental planning
In the 21st century, our world faces various challenges that greatly affect modern life and show the dynamic relationship and interaction of human activities with space and the environment and the immediate need to ensure sustainable development. The answers on how to achieve this interaction and...Read more

Long term solids handling alternatives for New York City water resource recovery facilities (WRRFs)
(Corresponding) Ramalingam K., (Corresponding) Fillos J., Katehis D.
Topic:
Energy technologies and sustainability
New York City Department of Environmental Protection, DEP, owns and operates 14 waste water treatment plants which treat a combined average dry weather flow of 57 m3/sec. (1.3 billion gallons per day). The plants have been upgraded periodically to address more stringent discharge permit limits with...Read more
Assessment of Concrete Footpath Upheavals in Heatwaves
(Corresponding) Bradford M.
Topic:
Climate change mitigation and adaptation
Most concrete footpaths are cast without steel reinforcement and in segments between bituminous joints, with the joints intended to accommodate thermal expansions (and contractions) of the pavement. However, a combination of prolonged heatwave conditions and the ingress over time of material into...Read more
Offshore windfarm siting in Greece using GIS and TOPSIS
SPYRIDONIDOU S., (Corresponding) VAGIONA D.
Topic:
Spatial environmental planning
The deployment of offshore wind power technologies is becoming increasingly important towards the sustainable development of regions. In Greece, wind energy is provided at the time being, only by onshore plants and the interest in investigating the top choices for offshore wind applications in...Read more
