Turning Plastic Waste into Power: Pyrolysis for Sustainable Industrial Energy
(Corresponding) Koumpakis D., Vlachokostas C., Michailidou A., Savva C.
Topic:
11. ENERGY TECHNOLOGIES
The research describes the creation of a basic pyrolysis system which industrial facilities can use to generate energy from their plastic waste. The system transforms 360 tons of plastic waste yearly into 160 tons of synthetic pyrolysis oil which powers a Combined Heat and Power (CHP) system. The...Read more

From Biogas to Propulsion and Power: A Life Cycle Perspective on Fuel Synthesis and CHP Integration
(Corresponding) Savva C., Michailidou A., Vlachokostas C., Koumpakis D., Toufexis C., Kandylakis C.
Topic:
5. ENVIRONMENTAL MANAGEMENT AND POLICY
Anaerobic digestion of organic waste offers a promising pathway for energy production and sustainable waste management. Within this framework, five pathways for biogas energy utilization were evaluated, and their environmental performance was compared, focusing on marine transportation and combined...Read more

Sustainability and Accountability in Agricultural Cooperatives: The Case of ZAGORIN through the GRI Lens
Paraschou M., (Corresponding) Sergaki P., Kalogeras N., Nastis S., Charatsari C., Michailidis A., Mattas K.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
This research explores the Agricultural Cooperative of Zagora (ZAGORIN), considered as one of the most sustainable and resilient agricultural cooperatives in Greece. It seeks to evaluate the perception and implementation of sustainability inside the cooperative, as perceived by its active members,...Read more
Integrating Citizens’ Engagement Model into The Circular Economy: A Multidimensional Approach to The Recycled Construction Materials Usage
(Corresponding) Butvilas T., Kovaitė K., Šūmakaris P.
Topic:
2. CIRCULAR ECONOMY AND BIOECONOMY
This paper proposes a multidimensional model to evaluate citizen engagement in the use of recycled construction materials, integrating individual, institutional, social, and technological dimensions. Drawing from existing literature and enhanced measurement indicators, the study synthesizes...Read more

Steps to Promote Agrifood Twin Transitions: From Identifying Innovation Paths to Enhancing Future Competencies
Charatsari C., Lioutas E., Sergaki P., Nastis S., (Corresponding) Michailidis A.
Topic:
12. CLIMATE CHANGE
Twin transitions aim to address grand challenges, such as climate change and food insecurity, through simultaneous systemic shifts toward more sustainable and digitalized production models. In this work, we present three key steps for supporting twin transitions. The first concerns the...Read more
Hydrogen Generation from Wastewater-Derived Organics via Solar Photocatalysis Using Low-Cost Cu-TiO₂ Composites
(Corresponding) Clarizia L.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Recent research has focused on developing Cu-based TiO₂ photocatalysts for sustainable hydrogen production via solar photoreforming of organic compounds typically present in urban and industrial wastewater. Copper, either in solution or integrated into TiO₂, forms heterojunctions that enhance...Read more
Performance Of Preoxidation And Coagulation In Arsenic Removal From Groundwater For Human Consumption In A Small Rural Community In Western Romania
(Corresponding) Pacala A., Neidoni D., Negrea S., Tenea A., Dinu C., Stefanescu M.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Health problems caused by high arsenic concentrations (over 200 μg/L) in groundwater sources in the Pannonian Basin (Hungary, Romania, Croatia, Serbia) have become a major concern for researchers and environmental experts. This paper evaluates the effect of the preoxidation (with hypochlorite)/...Read more
Removal of organic micropollutants by quaternary treatments controlled by optical sensors
Marino L., Gagliano E., Santoro D., Roccaro P.
Topic:
1. WATER AND WASTEWATER TREATMENT AND REUSE
Advanced oxidation processes (AOPs) are widely applied to degrade persistent organic pollutants. In view of new stringent regulations on organic micropollutants, the real-time monitoring of AOPs became crucial to fulfil the high quality standards over time. A fluorescence sensor was employed to...Read more
Optimized hydrodynamic cavitation-based Pretreatment Strategies to enhance residual Biogas Yield from Solid Digestate and Struvite Recovery from Liquid Fraction
(Corresponding) Nayak J., Khan A., Ranade V., Collins M.
Topic:
11. ENERGY TECHNOLOGIES
Digestate valorisation is essential for improving the sustainability and efficiency of anaerobic digestion systems. This study explores an integrated approach combining hydrodynamic cavitation (HC) pretreatment of the solid fraction with struvite precipitation from the liquid fraction to enhance...Read more
