Studies on the CO2 adsorption onto coal fly ash zeolites at elevated pressures
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
Coal fly ash zeolites (CFAZs) of Na-X type were prepared by ultrasonic-assisted double stage fusion-hydrothermal synthesis from lignite coal fly ash at two different fusion temperatures 550 and 800 C. The detailed surface analyses were performed experimentally using N2 physisorption technique and...Read more
Towards a sustainable water resources management in post-lignite era: the case of Western Macedonia, Greece
(Corresponding) Farmaki P., Tranoulidis A., Sotiropoulou R., Tagaris E.
Topic:
Water policy, management and society
In 2018, Public Power Corporation (PPC) employed 15,000 employees in the energy sector, mainly in lignite production, providing electricity to 6,900,000 customers in Greece. The total confirmed lignite reserves amount to 5 billion tons mostly resourced (1.8 billion tons) in the Western Macedonia...Read more

The potential impact of an implementation of microalgae-based wastewater treatment on the energy balance of a municipal WWTP in Central Europe
(Corresponding) Hasport N., Krahe D., Kuchendorf C., Theilen U., Beier S.
Topic:
Environmental biotechnology and bioenergy
The integration of a photobioreactor for wastewater treatment by microalgae is proposed as a future alternative for cost-efficient and environmentally friendly nitrogen and phosphorous removal in municipal WWTPs. The high growth rates and higher biogas yields (compared to conventional sewage sludge...Read more

Enhanced-Electrocoagulation For Organic Matter Removal From Surface Drinking Water Sources: Operational Parameters And Energy Consumption
(Corresponding) Daraei H., Intwala P., Awad J., Bertone E., Chow C., Duan J., Stewart R., Leuuwen J.
Topic:
Water treatment
In this study, an Enhanced Electro-Coagulation (En-EC) technique is described for the removal of dissolved organic carbon (DOC) from surface drinking water sources. Assessment of the En-EC technique included investigation of the impacts of operational factors on the organic removal efficiency (R%)...Read more

Energy Communities: A Significant Factor to alleviate Energy Poverty
(Corresponding) Lamprousis G., Golfinopoulos S.
Topic:
Energy technologies and sustainability
At the end of the 20th century, one of the phenomena that affect humanity on a social, economic, political, and environmental level is the energy poverty, a concept that is still misunderstood. It is a distinct form of poverty associated with a range of adverse effects for people’s health and...Read more

The environmental benefits of small-scale timber frame dwellings for utilization of forested and rural remote areas in Greece
(Corresponding) Psilovikos T., (Corresponding) Stergiadou A., Moutsopoulos D.
Topic:
Spatial environmental planning
Wood is the only renewable material produced by photosynthesis. Wood has the ability to preserve the stored carbon in its molecular structure as long as remain within a structure. Small-scalelightweight timber dwellings are gaining recognition in Europe after the dominance of concrete and steel...Read more
The role of biomass and biowaste in the green energy transition of islands and an introduction to the μgas-to-grid concept
(Corresponding) Vakalis S., Fountoulakis M.
Topic:
Energy technologies and sustainability
The green transition of the energy sector in islands has always been a challenging task. The connectivity of islands with the (mainland) central grid can be problematic, especially when the distance is significant. In such cases, isolated electrical grids need to be developed on the islands, and...Read more

(Corresponding) Senatore V., Giaquinto D., Zarra T., Oliva G., Buonerba A., Belgiorno V., Naddeo V.
Topic:
Energy technologies and sustainability
The development of resilient and sustainable cities emerged as a solution to tackle the several challenges arising from the exponential growth of urban areas population worldwide. The implementation of environmental technologies represents a solution to minimize negative impacts of crowded cities...Read more
Desalinated Water and Power for a Seaside Hotel: A Case Study using Off-grid Solar and Wind
Tounsi A., Ghamgui M., (Corresponding) Tadeo F.
Topic:
Environmental management and policies
A hybrid combination of solar and wind energies for a remote seaside hotel is analyzed. More specifically, a hotel in Hammamet, Tunisia, powered by photovoltaic panels and a wind turbine is evaluated, with water generated by desalination using reverse osmosis. This isolated accommodation...Read more
A review on the potential use of flammable gases from sewage systems as a source of energy
(Corresponding) Ghaffari M., Paurine A., Ali S., Mavroulidou M.
Topic:
Energy technologies and sustainability
The demand for natural resources has increased exponentially due to the consistent growth of the global population and urbanization. This has resulted to considerable environmental challenges that are potentially affecting the global sustainable development goals. Therefore, it is important to...Read more
