Photocatalytic elimination of water pollutants using innovative titania thin film heterostructures embedding carbon quantum dots
(Corresponding) Falara P., Zourou A., Ibrahim I., (Corresponding) Kordatos K.
Topic:
Water treatment
Titanium dioxide based photocatalysis is a well-established advanced oxidation process (AOP) that recently has expanded its borders comprising advanced reduction processes (ARPs) as well. To enhance the photocatalytic activity, titania heterostructures embedding semiconductors, or clays, or...Read more
Condensate originating from household food waste as a substrate for Microbial Fuel Cells
Kamperidis T., Pandis P., Vlachaki E., (Corresponding) Tremouli A., Lyberatos G.
Topic:
Environmental biotechnology and bioenergy
A microbial fuel cell (MFC) is a bioreactor that converts the chemical energy of the bonds of organic compounds to electrical energy, through the catalytic reactions of microorganisms. Under anaerobic conditions various substrates have been examined using MFC technology. This study examines the...Read more

The effect of catalysts MnO2, activated carbon and fly ash on the performance of single-chamber Microbial Fuel Cells
(Corresponding) Tremouli A., Kamperidis T., Pandis P., Stathopoulos V., Ieropoulos I., Argirusis C., Lyberatos G.
Topic:
Environmental biotechnology and bioenergy
Microbial fuel cells (MFC) are bioelectrochemical systems that convert the chemical energy contained in waste to electricity, using bacteria as catalysts. In order to boost the power output of MFCs, various approaches are feasible. This study examines the effect of using MnO2, activated carbon and...Read more
Gas mixture candidates for SF6 replacement in medium voltage switchgear: Analysis and modeling of the filling episodes
(Corresponding) Espinazo A., Lombraña J., Alonso M., Alonso R., Izcara J., Izagirre J., Pereda-Ayo B.
Topic:
Energy technologies and sustainability
A more environmentally friendly replacement for SF6 must be found for medium voltage switchgear, as a change in European regulations will come into force soon. The mixing process of alternative binary and ternary gas mixtures is studied, which are made up of the hydrofluoroolefin HFO-1336mzz(E) (...Read more

Decomposition products of 1,3,3,3-tetrafluoropropene and perfluoro-(3-methylbutan-2-one) gas mixtures in medium voltage electrical switchgear. Alternatives to SF6
(Corresponding) Alonso M., Alosno R., Espinazo A., Lombraña J., Izcara J., Izagirre J.
Topic:
Energy technologies and sustainability
In this work, binary and ternary gas mixtures of 1,3,3,3-tetrafluoropropene, HFO-1234ze(E), and perfluoro-3-methylbutan-2-one, CF3C(O)CF(CF3)2, with CO2 and synthetic air, are presented as alternatives to SF6 in medium voltage electrical equipment. They were used in four medium voltage switchgear...Read more
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

bioleaching, circular economy, metals recovery, red mud.
Photoluminescence spectroscopy on commercially available plastic products
(Corresponding) Konde S., Brackmann S., Hüppe F., Koch M.
Topic:
Case studies of macro- and microplastics pollution in coastal waters and rivers
Commercially available plastic products are produced for specific applications. They represent polymeric compounds, i.e. base materials mixed with various types of additives such as pigments. The identification of the plastic type is the key goal in microplastics analysis but also the key process...Read more
Can the seasonal variability affect the BMP of fruit and vegetable waste?
(Corresponding) Scotto di Perta E., Lamboglia R., Cesaro A., Frunzo L., Esposito G., Papirio S.
Topic:
Food waste
Fruit and vegetable waste (FVW), largely produced in open markets, is characterized by highly putrescible materials, thus being a proper substrate for anaerobic digestion. This study investigated the effect of the seasonal variation of FVW, on the biochemical methane potential (BMP). To this end,...Read more

Material flow analysis applied to a waste treatment plant in Lombardy (Italy)
(Corresponding) Castro F., Fabbri M., Vaccari M., Cutaia L.
Topic:
Solid waste management
Material flow analysis (MFA) allows to quantify inputs, outputs and stocks of a system and to communicate results visually. It can be used for calculating process effectiveness, losses and for identifying critical points within a system, being useful for strategically intervening in a corporative...Read more
Loureiro I., (Corresponding) Ribeiro C., Sepúlveda D.
Topic:
Environmental management and policies
Nowadays there is near consensus that cities have an important role to play in the pursuit of global climate protection and Sustainability. However, local strategies for sustainable development require a holistic and systemic approach, enabling multiscale involvement dynamics from a variety of...Read more
