Can Microalgae Revitalize Phytotoxic Soils?
(Corresponding) Vítová M., Jílková V., Čížková M., Kvíderová J., Elster J., Frouz J.
Topic:
7. ENVIRONMENTAL POLLUTION
Microalgae represent a variable group of photoauto-trophic microorganisms that include both prokaryotic cyanobacteria and eukaryotic algae. Compared to higher plants, algae have faster growth, higher photo-synthetic efficiency and the ability to colonize differ-ent ecological niches. The advantage...Read more
Optimizing the use of plastic materials from Walloon buildings for material and environmental innovation
Depretre A., Fotsing I., (Corresponding) Koutra S.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
The construction industry is one of the largest consumers of plastic materials, contributing significantly to global plastic waste and CO₂ emissions. This study focuses on optimizing the recycling and reuse of plastic materials in Walloon buildings, contributing to circular economic practices by...Read more

Comparison between different agri-food residual streams as direct source of biosurfactants
(Corresponding) Cruz J., Russo-Martínez N., Vecino X., (Corresponding) Moldes A.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
In this work various residues were evaluated as direct source of biosurfactants, observing that those coming from the wine, cider, and potato chip industries exhib-ited limited potential as direct sources of biosurfac-tants. Consequently, it should be recommended to evaluate their use as...Read more
Indoor air pollution: innovative solution for active purification treatments
Widolff M., Meyer Y., (Corresponding) Dutournie P.
Topic:
7. ENVIRONMENTAL POLLUTION
Indoor air is heavily polluted, much more so than outdoor air, but unfortunately it’s indoors that we spend most of our time. This pollution can have a real impact on health, which is why it’s necessary to treat it. To do this, various methods exist, including photocatalysis. Technopure is a French...Read more

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
