The study emphasizes the importance of water reuse strategies for mitigating global water scarcity and reducing environmental pollution.
An Overview of Wastewater Treatment and Reuse in The Gulf Cooperation Council Countries
This paper is not about microplastics — it reviews wastewater treatment technologies and reuse regulations across Gulf Cooperation Council countries, focusing on conventional and membrane treatment methods and the policy challenges of managing freshwater scarcity.
Addressing water resource management challenges in the context of climate change and human influence
This study identifies and documents the key challenges facing water resource management due to the combined pressures of climate change and human activity. Researchers found that droughts, floods, sea-level rise, and pollution are threatening both water quality and public health on a global scale. The study emphasizes that more sustainable approaches to water governance and infrastructure are urgently needed to address the growing gap between water supply and demand.
Water reuse: a pillar of the circular water economy
This review argues that water reuse is a foundational pillar of the circular water economy, shifting the paradigm from dissipative pollutant removal toward resource recovery and closed-loop water management. The authors examine how conventional wastewater treatment approaches must be reimagined to enable sustainable water circularity.
Groundwater resources: challenges and future opportunities
Researchers reviewed the major challenges and future opportunities in managing groundwater — a critical global water resource — emphasizing that sustainable use requires integrating new technologies, improved governance, and awareness of social, economic, and environmental factors unique to each region.
Wastewater Management Techniques: A Review of Advancement on the Appropriate Wastewater Treatment Principles for Sustainability
This review examines advancements in wastewater management techniques, focusing on approaches to ensuring that effluent released into the environment meets safety standards amid growing pressures from climate change and rising global population.
A sustainable brine and salt management strategy: An enabler for climate resilient water supplies for our community
Researchers examined sustainable brine and salt management strategies in Australia to address growing competition for high-quality water supplies driven by population growth, reduced rainfall, and industrial demand, outlining approaches to manage saline waste streams from desalination and water treatment.
Wastewater Reuse in the EU and Southern European Countries: Policies, Barriers and Good Practices
This paper reviews EU legislation on reusing treated wastewater and examines how southern European countries like Italy, Greece, and Spain are implementing these policies. While some progress has been made, the authors argue that current EU rules do not go far enough to encourage circular water solutions, particularly in overcoming regulatory and practical barriers. The review identifies both good practices and bottlenecks that prevent wider adoption of wastewater reuse across the region.
Revolutionizing Wastewater Reuse: A Critical Review of Innovative Treatment Technologies for a Sustainable Energy-Water Nexus
This review critically examines innovative wastewater treatment technologies for sustainable reuse, covering advances in membrane filtration, electrochemical processes, advanced oxidation, and emerging contaminant removal including microplastics, in the context of addressing global water scarcity.
Mitigating risks and maximizing sustainability of treated wastewater reuse for irrigation
This review examines the benefits and risks of using treated wastewater for crop irrigation, drawing heavily on Israel's experience as a world leader in this practice. While treated wastewater is a valuable water source, it can contain emerging contaminants including microplastics, pharmaceuticals, and pathogens that may affect soil health, crops, and human health. The authors call for better policies and global data sharing to ensure safe reuse of wastewater in agriculture.
Sanitary Systems: Challenges for Innovation
This paper reviews challenges for innovation in sanitation systems, including how to recover resources from waste while adapting to climate change and resource scarcity. Sanitation systems are also a major pathway for microplastic pollution to reach waterways through wastewater treatment plant effluent.
