ClearQuantification and Evaluation of Grey Water Footprint in Yantai
Researchers quantified grey water footprint — the freshwater volume needed to dilute pollutants to safe levels — in Yantai, China from 2014 to 2019, finding agricultural runoff was the dominant contributor and that overall footprint declined by 2019 following pollution control efforts.
From drainage to resource: a practice approach to reuse greywater for household irrigation purposes
This study reviewed practical approaches to reusing household greywater for irrigation purposes as a strategy for addressing freshwater scarcity. The research highlights that while treated greywater can reduce potable water consumption, concerns remain about contaminants including microplastics that may be present in greywater streams.
Microplásticos em água cinza
This study examined microplastic contamination in greywater (household wastewater from washing), finding that laundry and personal care product use introduce significant quantities of microplastics into domestic wastewater streams. The research highlights greywater as an underexamined pathway of microplastic release into water systems.
Water circularity index: A novel approach for authorities and operators
This paper proposes a novel water circularity index that evaluates both quantity and quality dimensions of water use across an entire usage cycle, going beyond traditional single-metric efficiency frameworks. The index is intended to help water authorities and operators assess and optimize the circular use of water resources in integrated systems.
Treatment of greywater and presence of microplastics in on-site systems
Researchers investigated microplastic occurrence in on-site wastewater treatment systems used for greywater, finding that these decentralized systems do not fully remove microplastics before discharge. The study highlights a poorly studied pathway for microplastics entering the environment.
Benefits and limitations of recycled water systems in the building sector: a review
Researchers reviewed the benefits and challenges of recycling greywater (lightly used household water) in buildings, finding it can improve concrete workability by 12–14% and reduce strain on freshwater supplies. While promising for sustainability, widespread adoption is held back by dual-pipe infrastructure costs, water quality concerns, and gaps in regulation.
Research status and prospect of microplastics in ship grey water
This review examines microplastic pollution in ship grey water, covering potential sources, current management measures, and progress in qualitative and quantitative analysis techniques for characterizing marine grey water microplastics. The authors propose future research directions including standardized analytical frameworks and improved estimation methods for marine plastic inputs from vessels.
Greywater Reuse: Contaminant Profile, Health Implications, and Sustainable Solutions
This review examines the safety of reusing household greywater (from laundry, bathing, and dishes) and finds it contains a wide range of contaminants including microplastics, pharmaceuticals, and pathogens. The authors highlight that microplastics from synthetic clothing fibers are especially common in laundry greywater. Reusing this water for irrigation or other purposes without proper treatment could introduce microplastics and other harmful substances into soil and food crops.
Emerging Pollutants in Wastewater: A Challenge for Water Reuse
This review examines emerging pollutants in wastewater as a central challenge for water reuse strategies, covering contaminants present at both domestic and industrial scales. It evaluates the sustainability benefits and treatment hurdles associated with recycling wastewater to address global water scarcity.
Novel Quantitative Evaluation of Biotreatment Suitability of Wastewater
This study developed a new framework for evaluating how suitable wastewater is for biological treatment, going beyond standard water quality indicators. Better assessment tools could improve wastewater treatment efficiency and reduce pollutant discharges, including microplastics.
Funktion hos enskilda anläggningar och en grön vägg för behandling av bad-, disk- och tvättvatten
This Swedish thesis examines the performance of decentralized greywater treatment systems including constructed wetlands and green walls, assessing their ability to remove pollutants including microplastics from household wastewater.
Identification of biomarkers in wastewater-based epidemiology: Main approaches and analytical methods
This review covers biomarker identification in wastewater-based epidemiology, examining how emerging contaminants including microplastics and pharmaceuticals in wastewater can serve as population-level indicators of disease, health behaviors, and chemical exposures in cities.
Wastewater matters: incorporating wastewater treatment and reuse into a process-based hydrological model (CWatM v1.08)
This study integrated wastewater treatment and reuse processes into the CWatM hydrological model, enabling large-scale simulation of how wastewater management affects urban water availability and hydrological dynamics.
Spatial Characteristics and Driving Forces of the Water Footprint of Spring Maize Production in Northern China
Researchers calculated blue, grey, green, and total water footprints for spring maize production across Northeast China's provinces and municipalities in 2019 and 2020, using the water footprint methodology to evaluate water-use efficiency. They found grey water footprints dominated (accounting for roughly 50-55% of total), identified significant spatial variation driven by irrigation practices and precipitation, and analyzed the key drivers of regional differences in agricultural water consumption.
Recycling – The future urban sink for wastewater and organic waste
Researchers analyzed how recycling urban wastewater and organic waste as agricultural fertilizer could become a sustainable solution for feeding a growing global population, finding that keeping nutrient-rich sewage separate from chemically contaminated greywater is essential to making this work. The analysis suggests that cities could replace environmentally damaging phosphorus and potassium mining with urban waste recycling if infrastructure is redesigned accordingly.
Effectiveness of conventional municipal wastewater treatment plants in microplastics removal: Insights from multiple analytical techniques
Researchers evaluated the effectiveness of conventional municipal wastewater treatment plants in removing microplastics across multiple treatment stages, finding removal efficiencies of 70–90% but documenting that billions of particles still pass through in final effluent daily.
Enhancing water quality prediction: a machine learning approach across diverse water environments
Researchers compared seven machine learning models for predicting water quality parameters using six years of wastewater treatment plant data. The gradient boosting model performed best overall, accurately predicting parameters related to water contamination. While the study focuses on general water quality rather than microplastics specifically, these predictive tools could be applied to monitoring microplastic-relevant conditions in treatment systems.
