Bioleaching of valuable elements from red mud using autochthonous biomass
(Corresponding) Cozzolino A., Cappai G., Cara S., Milia S., Carucci A.
Topic:
Circular economy and industrial symbiosis
Red mud (RM) is the main residue produced by the alkaline extraction of aluminum from bauxite, and it contains valuable metals (e.g., iron, aluminum, titanium, silicon). Aim of this research was to investigate the biologically induced leaching of valuable elements from RM using autochthonous...Read more

Optimum technical operating conditions and treatments for the production of high-purity struvite fertilizer from livestock wastewater.
Kallikazarou N., Koutsokeras L., Constantinide E., Constantinides G., (Corresponding) Antoniou M.
Topic:
Biowaste
Inadequate treatment of nutrient-rich waste streams originating from human activities such as agriculture, animal breeding, urbanization, and industrialization causes an array of environmental problems. Among them are eutrophication of surface water, nutrients and pathogens leaching into...Read more
Anaerobic Digestion of Municipal Wastewater (MWW) in a Periodic Anaerobic Baffled Reactor (PABR)
Zarkaliou A., Kougias C., (Corresponding) Papadopoulou K., Lyberatos G.
Topic:
Wastewater treatment
The scope of this work is to study the treatment of municipal wastewater in a Periodic Anaerobic Baffled Reactor (PABR). PABR is an innovative, high-rate bioreactor, designed to operate under high organic loadings. Apart from the Hydraulic Retention Time (HRT) an important operational parameter is...Read more

Environmental assessment using acoustic complexity indicators
(Corresponding) Tsaligopoulos A., Economou C., Matsinos Y.
Topic:
Biodibersity conservation
The procedure of sound recording offers new perspectives in ecology. Nevertheless, the existing tools that offer high resolution recordings are expensive. The use of acoustic indicators is proposed as an easy-to-use, rapid, non-intrusive, low-cost option in biodiversity assessment as well as in...Read more
Chromium VI bioremediation from Tannery Effluent and contaminated soil using Tamarindus indica leaves extract-immobilized nanoparticles
(Corresponding) Babangida S., Aliyu M., Abdullahi S.
Topic:
Heavy metals in the environment
The potential for application of bioreduction of Cr(VI) as an alternative to chemical remediation strategy has been highlighted in several works of literature. The objective of the study was to determine Cr(VI) reduction capacity of nanoparticles-encapsulated Tamarindus indica methanolic leaves...Read more

CO abatement via Ir-based catalysts: effect of the support and preparation method on catalytic activity and stability
Drosou C., Fountouli T., Stratakis A., Charisiou N., Goula M., (Corresponding) Yentekakis I.
Topic:
Air pollution
Here we report on the effect of the support and preparation method on the activity and stability of Ir-based catalysts under CO oxidation. Alunina-ceria-zirconia (ACZ: 60wt%Al2O3 - 40wt%CexZr1-xO2, x=0.25, 0.5, 0.75) mixed oxide supports with high oxygen storage capacity (OSC) were synthesized via...Read more
The expected dynamics of the wind conditions in the West Iberian nearshore, in the context of the climate change
(Corresponding) RUSU E.
Topic:
Environmental data analysis and modelling
The target area of the present study is the western side of the Iberian coastal environment. Although not so high as in the North or the Baltic seas, the wind power potential can be considered significant in this nearshore. Furthermore, since this coastal environment is rich also in terms of other...Read more
Keywords:
Iberian nearshore, wind power, maximum wind speed, near future, RCP4.5
Upgrading from biogas to biomethane is currently growing in Europe for economical and sustainable aspects. To date different treatments are proposed to upgrade biogas to a higher fuel standard. Among these, physico-chemical treatments are spreading widely in the biogas technology market...Read more
Sustainable management of solid waste by advanced decision-making tool
(Corresponding) Cieri V., Zarra T., Belgiorno V., Naddeo V.
Topic:
Waste management
Waste management has always been a critical problem globally. In the solid urban waste sector, generally, waste production is related to the people's lifestyles. The spread of COVID-19 has led to a drastic and unusual change in people's lifestyles. The adoption of a prolonged lockdown...Read more
Environmental Sustainability Indicators applied to Tourism Sector in Sicily
(Corresponding) Matarazzo A., Zerbo A., Serrano C.
Topic:
Environmental impacts of tourism and sustainable tourism development
Tourism is an important source of revenue for the economy of a country because it brings money to the State which use it as a source to improve services, buildings, facilities and tourism destinations. Its importance extends to a variety of studies and researches aimed to a better and more...Read more
