Green walls offer a novel on-site approach for greywater treatment and reuse in densely build urban environments. However, they need to be engineered effective removal of wide range emerging contaminants such as xenobiotic organic compounds (XOCs), which may present due extensive use personal care products household chemicals. This study used laboratory column design batch experiments investigate the performance three lightweight green wall media (coco coir, zeolite, perlite) their mixture different combinations twelve XOCs, covering hydrophilic, hydrophobic, charged pollutants greywater. The were designed assess targeted XOCs under operational condition (i.e., hydraulic loading, infiltration rate, drying) uncover dominant mechanisms removal. Results showed excellent (>90%) all coco coir mix columns at start experiment fresh initial 2 pore volume (PV) dosing). highly hydrophobic positively remained high conditions, while hydrophilic negatively exhibited significant reduction after 25 PV 50 PV, possibly low adsorption affinity electrostatic repulsion from media. effect rate on was not significant; however, higher achieved 2-weeks drying columns. mechanism most found adsorption, few acetaminophen atrazine) both biodegradation processes.

Abstract Greywater, comprising household wastewater excluding toilet waste, represents a significant portion of daily wastewater. Effective greywater treatment is crucial to mitigate environmental pollution, especially when flows directly into water bodies without clear controls, discharge limits, and requirements. Nature-based solution (NBS) approaches, such as green roofs, are gaining popularity for their urban benefits potential treatment. However, in Malaysia, the application literature on roofs limited, primarily focusing stormwater management. The remains understudied, despite numerous successful implementations worldwide. Hence, this study aims explore effectiveness improving quality. Two roof models were constructed: one using commercial materials other recycled coconut waste. Greywater samples from washing kitchen activities tested, with influent effluent analyzed key quality parameters including pH, turbidity, BOD, COD, TSS, TN, TP. Both demonstrated notable reducing BOD concentrations, achieving removal efficiencies between 12% 33%. resulting levels ranged 21 25 mg/L, which slightly above limit Standard A but compliant B Environmental Quality Act (EQA) 1974. While show greywater, treating limited. Addressing these shortcomings through system enhancements integrated approaches can lead more robust reliable solutions.

Water management in urban areas is challenged by climate change and increasing population, the reduction of water consumption becoming a major issue. Thus, domestic greywater (GW) can be valuable source for non-potable purposes, coupled with benefits provided nature-based treatment approach. In this context, green walls have been proposed GW local reuse, hence coupling advantage reuse The amount available linked occupancy habits inhabitants, but there still limited knowledge on impact variations flow rate efficiency health wall. Therefore, study aims to test resilience modular wall over 7 months. experiments were performed two configurations fed synthetic GW: one was constant (equivalent daily production per capita) as reference, while other received variable schedule. schedule included three phases: underload (-50 %), overload (+50 %) maintenance flow. Input output analysed evaluate performances fourteen physical-chemical parameters. Results showed that neither nor caused any detrimental effect or plants. Overload conditions slight decrease (e.g., 93.8 % BOD5 compared 100 recorded control configuration), plants exhibited visual signs distress. However, these negative effects disappeared after re-establishing standard rate. These findings demonstrated inflow variations. results provide useful indications application important design guidelines, terms maximum values organic loading (∼20 gBOD5 m-2 d-1) oxygen transfer (∼15 gO2 d-1), focusing building capacity driving parameter.

Common ivy (CI) or Hedera Helix L., is a clinging evergreen vine that can be cultivated on any vertical surface (walls, fences, tree trunks, etc.). In Europe, CI has been recommended by governments to plant in urban areas because it lowers heat island effects and improves air quality. Regular trimmings of these greenery systems would necessary, which yield potentially interesting novel biomass resource for biorefinery concepts. Furthermore, extracts contain pharmaceutically active compounds (e.g., hederacoside C α-hederin), constitute the components commercially available cough syrups. Moreover, research their suitability treat (lung) inflammations suppress cancer tumor growth ongoing shows promise. also have demonstrated potential application agricultural industry serve as antifungal agents. Recently, postextracted residues shown promising feedstock green fertilizer production via slow pyrolysis. provisional sustainability assessment indicated proposed process both carbon- energy-negative. Therefore, circular approach proposed, entails lifecycle CI, from cultivation ecosystems refinery into bioproduct(s) valuable nutrients, then back soil.
