50th ISTANBUL International Conference on Green Technologies & Sustainable Engineering (IGTSE-26) scheduled on April 29-May 1, 2026 Istanbul (Türkiye) is for the scientists, scholars, engineers and students from the Universities all around the world and the industry to present ongoing research activities, and hence to foster research relations between the Universities and the industry. This conference provides opportunities for the delegates to exchange new ideas and application experiences face to face, to establish business or research relations and to find global partners for future collaboration. The conference is sponsored by Universal Researchers (UAE). All the submitted conference papers will be peer reviewed by the program/technical committees of the Conference.

Green Engineering & Resource Management

This pillar focuses on minimizing resource depletion, waste, and pollution in industrial processes.

• Circular Economy & Waste Valorization:

  • Life Cycle Assessment (LCA): Quantifying the environmental impact of a product from "cradle to grave" (or "cradle to cradle").

  • Resource Efficiency: Industrial symbiosis (waste from one facility becomes feedstock for another).

  • Advanced Recycling: Chemical recycling (breaking polymers back into monomers), upcycling, and Urban Mining (recovering precious metals from e-waste).

• Green Chemistry & Green Chemical Engineering:

  • Sustainable Solvents: Using water, supercritical CO2, or ionic liquids instead of hazardous organic solvents.

  • Catalysis: Developing highly selective, non-toxic catalysts (Biocatalysis, Photocatalysis).

  • Process Intensification (PI): Using technologies like microreactors and reactive distillation to increase efficiency and safety while reducing plant size.

• Sustainable Materials Science:

  • Green Materials: Bio-based and biodegradable polymers, sustainable concrete alternatives (low-carbon concrete), and self-healing materials.

  • Sustainable Manufacturing: Additive manufacturing (3D printing) for reduced material waste, and closed-loop manufacturing systems.

 Environmental Mitigation & Climate Tech

This area covers technologies designed to remove pollutants and address climate change directly.

• Carbon Management:

  • Carbon Capture, Utilization, and Storage (CCUS): Post-combustion capture, Direct Air Capture (DAC) technologies, and conversion of CO2 into fuels or chemicals (CO2 Utilization).

  • Carbon Sequestration: Natural (forestation, soil management) and enhanced mineralization.

• Water Management & Treatment:

  • Desalination: Energy-efficient membrane technologies (Reverse Osmosis, Nanofiltration).

  • Wastewater Treatment: Advanced Oxidation Processes (AOPs), resource recovery from wastewater (nutrients, energy).

• Pollution & Remediation:

  • Air Pollution Control: Advanced systems for removing NOx, SOx, and fine particulate matter.

  • Contaminant Removal: Technologies for remediating soils and water contaminated with emerging contaminants (e.g., PFAS, microplastics).

 Sustainable Infrastructure & Cross-Disciplinary Topics

These topics integrate the core technologies into the built environment and leverage advanced computation.
