Topic:
Biowaste
Aim of this study was to evaluate the anaerobic co-digestion of diluted poultry manure (DPM) and used cooking oil (UCO). Mixtures of DPM with different UCO dosages (1 to 6% v/v) were prepared using a high-shear emulsifier and digested in batch anaerobic reactors. Increasing the UCO dosage resulted...Read more

Screening thousands of emerging contaminants in Asopos river basin by UPLC-QToF-MS
Nikolopoulou V., Nika M., Aalizadeh R., Alygizakis N., (Corresponding) Thomaidis N.
Topic:
General
Monitoring activities over several decades have revealed the ubiquitous presence of organic contaminants in environmental compartments. Asopos river basin, located in Sterea Ellada, has been the focus of many environmental studies over the last decades, mainly due to its geomorphology and the...Read more

Investigating the water, energy, marine land use, food, climate interlinkages in marine environment
(Corresponding) Papadopoulou M., Vlachou A.
Topic:
Spatial environmental planning
The conflicts observed in the marine environment between the installation of renewable energy production, aquaculture activities and tourism, highlight the need for a more coherent management. To this end, maritime spatial planning is being developed at the cross-sectoral level, so that human...Read more
The green strategies together with decisions create a business ecosystem in the Environmental Goods and Services Sector (EGSS). Such an ecosystem is a result of both technological development and strategy evolution. This paper aims to present and discuss the outcomes (as relations) of this sector...Read more

Transferring the Carbonation of Biomass Bottom Ash from Batch to Continuous Operation
(Corresponding) Schnabel K., Brück F., Pohl S., Weigand H.
Topic:
Mineral carbonation of alkaline waste materials
Biomass incineration residues may be used for CO2 capture and storage by carbonation of waste-borne metal hydroxides. Moist carbonation of these ashes can be performed under mild conditions (ambient pressure and temperature) and accelerated by using a CO2-rich gas. The process requires the wetting...Read more

Degradation of textile dyes in water by gas-liquid NSP-DBD plasma
MEROPOULIS S., (Corresponding) AGGELOPOULOS C.
Topic:
Advanced oxidation processes
Textile dyes represent some of the most complicated environmental pollutants due to their variety and complex structure. Cold atmospheric plasma (CAP) is regarded as a highly competitive advanced oxidation process towards the removal of organic pollutants from wastewater. In this study, a gas-...Read more
Silver decorated TiO2/g-C3N4 nanocomposites for photocatalytic elimination of water pollutants under UV and artificial solar light
Ibrahim I., Belessiotis G., Kaltzoglou A., Katsaros F., Salama T., (Corresponding) Falaras P.
Topic:
Water treatment
TiO2/g-C3N4/Ag nanocomposites were prepared and used as highly efficient photocatalysts. TiO2 nanoparticles were first prepared using a sol-gel process, and titania herostructures with varying amounts of graphitic carbon nitride (g-C3N4) were created using a hydrothermal technique. Following...Read more

TiO2/g-C3N4/Ag nanocomposites; UV and artificial solar light; Organic-inorganic pollutants degradation.
An innovative and eco-friendly approach to recover gold (and copper) from gold fingers of waste printed circuit boards
Sousa P., Martelo L., Bastos M., Marques A., (Corresponding) Soares H.
Topic:
Sustainable supply of raw materials
Recycling waste printed circuit boards (WPCBs) is a complex problem worldwide and sustainable technologies are required. So, this work aims to offer an innovative (an European patent was submitted, EP 20216239.2 1) and more sustainable solution to recover high-value materials (gold and copper) from...Read more

Preliminary hydro-geochemistry characterization of the complex geological framework of the Coreca area (Calabria, South Italy).
(Corresponding) Vespasiano G., Apollaro C.
Topic:
Hydrology and water resources
Hydrogeochemical characterization combined with statistical methods has been used to investigate groundwater quality and related geochemical processes in the complex geological framework of Coreca (Calabria, South Italy). Coreca is characterized by a peculiar geological setting that affects the...Read more
