Summary: In developed countries, poor indoor air quality has a significant impact on human health. The burden of disease related to indoor air pollution leads to millions of premature deaths. CO2 is the most common indoor air pollutant, and its concentration can be higher indoors due to human activities. Despite ventilation efforts, controlling CO2 concentration below recommended levels is a challenge, with many indoor environments exceeding the threshold. This review explores the issues associated with poor indoor air quality and highlights the potential of indoor CO2 direct air capture to purify air and contribute to the circular economy.

Summary: Biowaste management has gained increased attention due to the focus on Circular Economy practices. A study was conducted on Lesvos to address Olive Mill Wastewater (OMWW), which is a significant wastewater stream on the island due to the presence of food processing facilities and olive mills. The study developed a holistic experimental set-up that combines aerobic and anaerobic treatment strategies, focusing on the hydrothermal carbonization (HTC) of anaerobic residues from biogas production. The results showed that utilizing food waste and spent coffee grounds (SCG) together had an impact on the final products, with enhanced methane yields and hydrochar production. The study also highlighted the potential of using OMWW as a medium for HTC, resulting in reduced COD and hydrochars with increased heating values.

Summary: Odor management plans require identifying odor sources in waste management facilities. This article presents a new approach using field olfactometry and spatial interpolation for odor quantification and source identification in a selected waste management facility. The results show that field olfactometry is a suitable tool for odor identification, but the selected interpolation method has high errors and tends to overestimate odor concentrations. Its inability to handle points below the detection threshold raises questions about its usefulness in odor management plans. Further research into computational methods, including advanced interpolation methods or dispersion modeling based on field olfactometry data, is needed.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
