Preliminary Research on the Removal of Organic Compounds from Leather Tanning Wastewater
(Corresponding) Umiejewska K., Polański Ł., Pietraszek P.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Leather tanning consists of many processes, most of which are carried out using water, in which variety of chemical compounds, mineral tannins (including chromium (III) salts) and vegetable tannins, dyes etc. are added. In combination with organic matter of animal origin it results in wastewater...Read more
Adsorption of Cd2+ Using Brick-Sludge Composite: A Circular Economy Approach
(Corresponding) Gheibi M., Palušák M., Silvestri D., Černík M., Wacławek S.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Cadmium (Cd), a highly toxic element, often contaminates drinking water through Cd²⁺ impurities in galvanized pipelines and cadmium-based solders. This study presents a sludge-brick composite for Cd²⁺ decontamination, aligning with circular economy principles. Using Response Surface Methodolo-gy (...Read more

Catalytic activation of peracetic acid to decompose micropollutants in water
Jeon S., Choi C., Choi A., Lee H., (Corresponding) Changseok H.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Acetaminophen (APAP), a widely used pharmaceutical, is frequently detected in aquatic environments due to its persistence and limited removal by conventional wastewater treatment processes. In this study, a peracetic acid (PAA) based advanced oxidation system was developed using magnetically...Read more
Ammonia is a common pollutant in wastewater, and its removal is essential to prevent environmental issues such as odors and eutrophication, which can harm aquatic ecosystems and human health. While traditional treatment methods are energy-intensive and costly, ammonia has garnered attention as a...Read more
Comparison of Ceftriaxone, Ofloxacin, and Metformin Adsorption onto Activated Carbon from Aqueous Solutions
Hanganu D., Favier L., Lutic D., (Corresponding) Harja M.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Pharmaceutical compounds have been widely identified as organic pollutants in wastewater with adverse effects on the environment. This paper focuses on three active substances: ceftriaxone, ofloxacin, and metformin. The main reason for the interest is their ability to be excreted 80-90%...Read more
Οptical and microphysical properties of Saharan and Saudi Arabian desert based on AERONET data products
(Corresponding) Giannakaki E., Koutounidis I.
Topic:
7. ENVIRONMENTAL POLLUTION
The study investigates possible differences between the Saharan and Saudi Arabian deserts' dust particles based on AERONET network. Our results shows that while particle depolarization ratio values at 440 nm were similar for both regions, the Saudi Arabian lidar ratio (at 440 nm) was...Read more
Aerosol Characterization Based on Graphical Method of Gobbi Diagrams
(Corresponding) Koutounidis I., Giannakaki E.
Topic:
7. ENVIRONMENTAL POLLUTION
A practical graphical approach for translating å and its spectral curvature (Δå) into estimates of fine-mode aerosol radius and its contribution to total AOT was proposed by Gobbi et al. (2007). In the present study, we utilize AERONET Version 3 Level 3 data—specifically lidar ratio and...Read more
Smart container tracking: A sustainable path for modern port management
Aidonis D., (Corresponding) Achillas C., Tsolakis N., Folinas D., Kotsoglou A., Tserga E.
Topic:
5. ENVIRONMENTAL MANAGEMENT AND POLICY
The rapid expansion of global trade and the increasing complexity of supply chains have highlighted the necessity for robust ICT solutions in modern logistics. Traditional methods of managing container movements are no longer sufficient to address inefficiencies, delays, and environmental concerns...Read more

Patenting Trends in Agricultural Climate Innovation: A Global Analysis with a Focus on China
(Corresponding) Pavesi R.
Topic:
12.2 Climate change adaptation and resilience
Agriculture faces mounting pressure to both adapt to climate change and mitigate its environmental impact. Green technology innovation is central to this challenge, yet little is known about how global patenting trends reflect the balance between adaptation and mitigation efforts. This study...Read more
Exploring the Efficacy of Slow Sand Filtration for Sustainable Water Purification
Brickhill G., (Corresponding) Sheridan C.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Slow sand filtration (SSF) demonstrates adaptability and resilience when applied to variable river water sources, making it a promising potential solution for sustainable water purification. This study investigates SSF’s ability to remove E. coli, nitrates (NO₃), and phosphates (PO₄) over 12 weeks...Read more
