Geocoding of fire events in the mountainous region of Ymittos using GIS
(Corresponding) Kelesidi K., Tsouchlaraki A.
Topic:
12. CLIMATE CHANGE
Wildfires in Greece constitute a major environmental challenge with significant ecological, economic, and social impacts. In recent years, their frequency and intensity have increased due to climate change, urban expansion, and lack of integrated planning, making effective management a critical...Read more
Adsorption of Ciprofloxacin by Sugarcane Bagasse Activated Biochar in Aqueous Solution
(Corresponding) Ubiña L., Guia R., Aquino C., Somera L., Balela M., Beltran A., Cornista J., Bautista-Patacsil L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Antibiotics such as ciprofloxacin (CIP) in wastewater pose a significant and pressing concern as an emerging contaminant. Conventional wastewater treatments are not optimized to effectively remove antibiotics, resulting in their persistence in bodies of water and significantly contributing to a...Read more

Emerging Contaminants of Concern, Ciprofloxacin, Antimicrobial Resistance, Activated Biochar, Adsorption
Investigation of waste-derived adsorbents for removal of NORM and non-regulated elements from mining wastewater
(Corresponding) Avsar D., Pelkonen M., Gajendra N., Grønvold R., Angyus B., Dinis M., Vila M., Yilmaz D., Senila M., Ferrando-Climent L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
The growing demand for rare earth elements (REEs) has led to an increase in mining activities, raising significant environmental concerns, particularly related to wastewater (WW) management. Mining WW can contain a complex mixture of contaminants, including naturally occurring radioactive materials...Read more
Optimizing biological consortia for mining wastewater treatment
(Corresponding) Gajendra N., (Corresponding) Török A., Avsar D., Pelkonen M., Grønvold R., Dinis M., Vila M., Yilmaz D., Levei E., Ferrando-Climent L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Industrial processes, such as the mineral extraction of raw materials, have been in crucial focus because of the current drive towards greener and more sustainable energy sources. Hence, the production workflow of critical elements, such as rare earth elements (REEs), is reassessed to identify less...Read more

Simulation-based design of pressure swing adsorption for methane and nitrogen separation in biogas upgrading
De Paola S., Cairone S., Oliva G., Cardona G., Zarra T., Belgiorno V., (Corresponding) Naddeo V.
Topic:
11. ENERGY TECHNOLOGIES
This study evaluates the performance of three adsorbents, ETS-4, MSC 3K 172, and Norit RB3, for a 68/32 %vol CH4/N2 separation in biogas upgrading, using a two-stage Pressure Swing Adsorption (PSA) system modeled in Aspen Adsorption. Sensitivity analysis indicated that adsorption pressure,...Read more
Development of 3D-Printed Permeable Reactive Barrier Adsorbents Utilizing Zeolite Composites for Copper (II) Removal in Acid Mine Drainage
Atega M., Detras M., Eusebio R., Borines M., Maalihan R., (Corresponding) Bautista-Patacsil L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Zeolite-based ceramic structures was fabricated using a viscous solution 3D printing (3DP) technique to demonstrate their effectiveness in removing heavy metal ions from acid mine drainage (AMD) runoff. Zeolite, a low-cost hydrated aluminosilicate clay, is widely used in water treatment due to its...Read more

Exploring the applicability of differential absorbance to simultaneously quantify and control microbial inactivation and DBPs formation
Baccini L., Vagliasindi F., Korshin G., (Corresponding) Roccaro P.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Chlorination is effective in inactivating microorganisms. However, its interaction with natural organic matter (NOM) and inorganic ions leads to the formation of disinfection byproducts (DBPs). Surrogate parameters, such as the differential absorbance at 272 nm (DA272), have shown potential for...Read more
Bio-oil production from biomass pyrolysis via a hybrid mathematical and machine learning approach
Xu F., Lyons Ceron A., Neshumajev D., (Corresponding) Konist A.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
A hybrid mathematical and machine learning (HMML) approach is applied for maximizing bio-oil yield during the continuous biomass pyrolysis, using local common reed as feedstock. The HMML approach, which combines Response Surface Methodology (RSM) and Machine Learning algorithms (Gaussian Process (...Read more

Reclaiming Water: Assessing the Water Resources Released by the Decommissioning of Lignite Facilities in Western Macedonia
(Corresponding) Farmaki P., Tranoulidis A.
Topic:
9. HYDROLOGY AND WATER RESOURCES
The decommissioning of lignite power plants in Western Macedonia is a key point for the energy transition at a national level in Greece but also marks a turning point for the regional resources management. One of the resources of special interest would be water, a central ingredient in the lignite-...Read more

Multi-Analytical Investigation of Oil Shale and Its Ash Fractions: Trace Element Partitioning and Environmental Implications
Yang D., Paiste P., Konist A., (Corresponding) Järvik O.
Topic:
7. ENVIRONMENTAL POLLUTION
This study presents a comprehensive multi-analytical investigation of oil shale and its combustion ash fractions using XRD, XRF, and LA-ICP-MS techniques. The mineralogical composition is characterized by a transition from carbonate-rich phases in raw shale to silicate-dominated assemblages in ash...Read more
