The Hybrid MVR–AnEMBR Project aims to establish a closed-loop system capable of treating landfill leachate while recovering valuable resources. The project’s objectives are organized into three interconnected dimensions: technological, environmental, and socioeconomic.
Ammonia Recovery via MVR:
Design and optimize a Mechanical Vapor Recompression (MVR) process to selectively separate and recover ammonia from raw landfill leachate.
The recovered ammonia will be stabilized and converted into ammonium sulfate fertilizer [(NH₄)₂SO₄], enabling nutrient reuse in agriculture.
Enhanced Methanogenesis via AnEMBR:
Develop an Anaerobic electro-Membrane Bioreactor (AnEMBR) to improve anaerobic digestion efficiency, accelerate electron transfer, and enhance methane generation from organic-rich leachate.
Hybrid System Integration:
Engineer an integrated MVR–AnEMBR platform that maximizes energy reuse, reduces chemical input, and achieves near-zero discharge operation.
Modeling and Optimization:
Apply computational modeling and data-driven optimization (e.g., AI-assisted parameter tuning) to predict system performance and scale-up potential.
Life Cycle Assessment (LCA):
Evaluate the environmental sustainability of the hybrid process through LCA, quantifying its carbon footprint, energy efficiency, and potential environmental trade-offs.
Water Recovery and Reuse:
Recover purified water from the leachate stream to contribute to water conservation in industrial and agricultural applications.
Pollution Minimization:
Reduce nitrogen, COD, and refractory organics in the effluent to meet or exceed discharge standards, minimizing ecological toxicity.
Circular Economy Integration:
Align with national and EU circular economy directives, promoting waste-to-resource technologies.
Food & Energy Security:
Support sustainable agriculture through fertilizer recovery and generate renewable bioenergy to offset fossil fuel dependence.
Knowledge Transfer & Training:
Build interdisciplinary research capacity among young environmental engineers and scientists, fostering innovation in sustainable waste treatment.
The project outcomes are expected to redefine leachate management practices and contribute to multiple Sustainable Development Goals (SDGs).

The hybrid system provides a scalable demonstration of how waste treatment and resource recovery can coexist within the same framework. It integrates:
Thermodynamic efficiency (via MVR),
Bioelectrochemical enhancement (via AnEMBR), and
Systems-level sustainability (via LCA and circular design).
Ultimately, the project supports Turkey’s National Zero Waste Initiative and contributes to global sustainable development agendas, offering an adaptable model for industrial wastewater valorization worldwide.
