A novel synergistic bioleaching approach to phosphor powder recycling
(Corresponding) Duffield Healy M., Robinson L., Farnaud S.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
Efficient scalable rare earth separation processes are a topic of great importance as technologies such as renewable energy and electrical vehicles begin to take root. To assist in the amelioration of this issue this paper reports a method by which low pH and high pH leaching are used...Read more

Application of Ozonation-Based Processes to Reduce Environmental Impact of Waste Antibiotics
(Corresponding) Žgajnar Gotvajn A., Derco J., Čehovin M.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
The aim of the work was to determine the efficiency of direct ozonation, ozonation at elevated pH, ozonation at elevated pH with the addition of hydrogen peroxide, catalytic ozonation, photo-catalytic ozonation, ozonation with Fenton oxidation and ozonation with photo-Fenton oxidation for removal...Read more
Life Cycle Assessment of grape production. Potential environmental benefits of an alternative solution for fungal diseases control
Zoli M., Pavesi R., Orsi L., (Corresponding) Bacenetti J.
Topic:
5. ENVIRONMENTAL MANAGEMENT AND POLICY
In the project Grape4Vine an innovative solution was developed. In detail, the Grape4vine project aims at exploiting winegrowing byproducts that would be normally treated as wastes, to produce biotechnological means for controlling downy mildew and powdery mildew in the circular economy context. In...Read more

Wastewater Reclamation – opportunities and challenges
(Corresponding) Zubrowska-Sudol M., Knap-Baldyga A., Czajkowska J.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Water scarcity poses a growing global challenge, intensified by climate change, population growth, and rising water demand. Municipal wastewater reclamation offers a sustainable solution, transforming waste into a resource. This study, conducted within the ReNutriWater project, evaluates the...Read more

Circular Economy through Berry Pomace Valorization
(Corresponding) Ispiryan A., Butu A., Jariene E.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
This investigation delineates the economic aspects associated with the valorization of pomace derived from ten distinct berry varieties within the context of the circular bioeconomy paradigm. Through the implementation of a comprehensive marketing costs and returns (MCR) analysis, this research...Read more
Fermentation-Driven Enhancement of Berry Pomace: Proximate Composition and Functional Properties Evaluation
(Corresponding) Ispiryan A., Butu A., Jariene E.
Topic:
4. SOLID WASTE MANAGEMENT
This investigation centers on the change of berry pom-ace via fermentation, aimed at augmenting its nutri-tional profile and functional characteristics, within the framework of a circular economy paradigm. By employ-ing a thorough proximate composition analysis, the study assesses the moisture, ash...Read more

(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
