Session Description / Call for Papers:

Islands around the world are at the frontline of sustainability challenges linked to tourism, including seasonal pressures, limited natural resources, waste accumulation, and increased energy demand. Addressing these challenges requires innovative, circular, and systemic approaches that are adaptable to local conditions and engage communities and visitors in meaningful ways.

We invite contributions that explore solutions for circular economy implementation in island tourism contexts, including but not limited to:

• Movable or modular systems for waste, water, or energy management
• Circular models tailored for tourism-intensive island communities
• Stakeholder engagement and co-creation methods in sustainability planning
• Digital tools and monitoring systems to support resource efficiency
• Case studies from islands in any global region
• Governance, financing, and policy mechanisms enabling circular transitions

We welcome interdisciplinary submissions, including original research, applied case studies, technology demonstrations, and policy analyses that advance circularity and resilience in island tourism.

Keywords: sustainable tourism, circular economy, island resilience, movable infrastructure, stakeholder engagement, decentralized systems, modular technologies, co-creation

Submission Info:
Submit your abstract (500 words) or paper (max 2 pages) via the CEST2025 abstract submission portal. When submitting, select the special session titled “Circular Systemic Solutions for Sustainable Tourism on Islands.”

Title of the speech: Quaternary treatments in the upgrading of WWTPs in accordance with the recent UWWTD: micropollutant removal and operation reliability

Session Description / Call for Papers:

The revised Urban Wastewater Treatment Directive (EU Directive 2024/3019) represents a significant policy milestone, placing greater emphasis on the removal of micropollutants and contaminants of emerging concerns (CECs) from urban wastewater. The Directive outlines new treatment requirements and introduces an Extended Producer Responsibility (EPR) mechanism to support the transition to safer and more sustainable water management across Europe.

This special session at CEST2025 aims to gather researchers, water professionals, technology developers, and policymakers to share knowledge, tools, and experiences in the monitoring, removal, and risk assessment of micropollutants within the framework of urban wastewater reuse and circular economy principles.

We welcome contributions in the following thematic areas:

• Advanced treatment technologies for the removal of micropollutants (e.g., ozonation, activated carbon, AOPs, membranes)
• Occurrence, fate, and behavior of emerging contaminants in urban wastewater
• Analytical methods for detection and monitoring of pharmaceuticals and other micropollutants
• Treatment train design and process optimization to comply with EU 2024/3019 requirements
• Micropollutant removal in the context of water reuse for agriculture, urban, and industrial applications
• Risk assessment and environmental safety of reclaimed water
• Cost-benefit analysis for quaternary treatment of wastewater
• Nature-based solutions and integrated approaches for contaminant reduction
• Policy, governance, and financing frameworks—including Extended Producer Responsibility
• Case studies and best practices from utilities and municipalities
•  

Keywords: Urban Wastewater Directive 2024/3019; micropollutants; emerging contaminants; quartenary treatment; water reuse; wastewater reuse; EPR; wastewater regulation, water safety

The UrbanWaterSecurity Academy is an international initiative dedicated to 

advanced training in the sustainable management of urban water resources. 

Through a multidisciplinary approach, the Academy aims to develop essential 

skills and knowledge to address the challenges associated with urban water 

security, a critical issue in the face of rapid urbanization and climate change.

The UrbanWaterSecurity Academy has successfully organized three editions to date:
• First Edition (2022): Held in Salerno, Italy, this inaugural edition laid the foundation for the Academy's mission to address urban water security challenges.
• Second Edition (2023): Conducted in Athens, Greece, from August 30 to September 2, 2023.
• Third Edition (2024): Took place in Paestum, Italy, from June 14 to June 16, 2024, at the Oleandri Resort.

Founded to meet the growing need for innovative and sustainable water management solutions, the Academy is supported by leading academic institutions and international organizations. The Academy provides a unique learning experience that combines theoretical knowledge with practical applications, focusing on innovative solutions to:

1. enhance water quality,
2. optimize water usage, and
3. ensure resource resilience in urban environments. 

It brings together young researchers, professionals, and industry experts to exchange ideas, collaborate on sustainable projects, and promote a resilient urban water future.

The fourth edition of the UrbanWaterSecurity Academy will be held on the island of Kos, Greece, from September 2 to 6, 2025, in conjunction with the CEST2025 Conference (Conference on Environmental Science and Technology). This year’s Academy is organized by the Waste Management Laboratory of the Department of Environment at the University of the Aegean (Greece), in cooperation with the Sanitary Environmental Engineering Division (SEED) of the University of Salerno (Italy).

Topics

The UrbanWaterSecurity Academy offers intensive training designed 

for Master’s and Ph.D. students, post-doctoral researchers, and early-career professionals. This program meets the growing demand for expertise in urban water security by providing a comprehensive understanding of fundamental principles, practical applications, and innovative technologies for urban water management. 

The Academy encourages participants to integrate technical knowledge with broader environmental and societal contexts, equipping them to address present and future water challenges in urban environments. The curriculum is developed by a distinguished program committee, which ensures high-quality instruction by selecting top-tier experts in the field.

The Academy program will include:

• Lectures by Leading Experts: Providing both theoretical foundations and

real-world case studies, these sessions will highlight innovations in urban 

water security, resource recovery, and resilience planning.

• Hands-On Workshops: Interactive sessions focusing on the urban water system 

design, management of emerging contaminants, and climate adaptation 

strategies, complemented by hands-on demonstrations.

• Discussions and Q&A Sessions: Opportunities for participants to engage 

with experts on current challenges, future developments, and critical trends in 

urban water security.

• Technical Tours: Field visits to water management facilities in Kos, Greece, 

offering firsthand insights into advanced practices in urban water treatment 

and sustainable resource management.

This edition will feature prestigious educators, each a global leader in urban water science and technology, including winners of the prestigious PSIPW awards. Their expertise will broaden participants' perspectives and prepare them to lead impactful change. Participants will engage in six specialized modules comprising six comprehensive classes, seven class works, and one technical tour.
