In the fight against climate change, technology is important for reducing waste emissions. Hence, in this study, greenhouse gas emissions and carbon credit values of municipal solid waste (MSW) disposal facilities such as sanitary landfill, waste incineration and biogas facilities in Istanbul are analyzed for the year of 2023, using real facility data based on IPCC and Gold Standard methodologies. The results obtained are comprehensively evaluated with the related literature studies. The annual non-biogenic emissions per t of waste were found to be: 0.461 tCO<sub>2</sub>e for Kemerburgaz waste incineration; 0.457 tCO<sub>2</sub>e for Seymen LFG and 0.001 tCO<sub>2</sub>e for Kemerburgaz biogas. In addition, it is determined that the waste incineration facility has the highest carbon credit amount with 1,469,676 tCO₂e. Carbon reduction of 1,257,087 tCO₂e is achieved in the sanitary landfill facility and 16,340 tCO₂e in the biogas facility. Energy generation per t of waste was also highest in the incineration facility (0.59 MWh), compared to the biogas facility (0.19 MWh) and LFG facility (0.09 MWh).

The efficiency of the process was affected by scaling on the membranes, particularly in the presence of Fe2 + .

The results demonstrate that while ground-based data can offer valuable insights, combining these datasets with satellite information significantly enhances predictive performance. Accurate prediction of particulate matter 2.5, a harmful air pollutant linked to respiratory and cardiovascular diseases, is critical for managing air quality in densely populated cities. This study compares remote sensing data with four configurations of ground data, meteorological and traffic data, and a combination of remote sensing and meteorological data in predicting particulate matter 2.5 concentrations across Tehran’s 22 districts. Ground data included meteorological factors, traffic data, and direct air quality measurements, supplemented by satellite-based aerosol optical depth estimates from NASA’s HD4 archives via Google Earth Engine. Using machine learning, deep learning, and statistical models, study evaluated the predictive accuracy of each dataset. The findings show that remote sensing data consistently outperforms all ground data configurations, offering superior performance and flexibility. This indicates that satellite-based remote sensing is an effective, independent tool for particulate matter 2.5 prediction, particularly in regions lacking ground monitoring infrastructure. These results underscore the potential of satellite-derived particulate matter 2.5 estimates for public health research and air quality management.

The primary objective is to identify an effective and eco-friendly alternative to conventional adsorbents for the post-treatment of effluents from Upflow Anaerobic Sludge Blanket (UASB) reactors. COD and phenol are targeted due to their environmental significance; COD reflects overall organic pollution, while phenol is a toxic, persistent compound in oily industrial wastewater. Multi-level factorial design experiments optimized using three types of adsorbent materials with different doses to improve the Biofilter performance. COD removal and phenol were studied as a function of four experimental parameters: adsorbent materials, dose, contact time, and wastewater type. To minimize the number of experiments, MINITAB Version 19 software conducted the experiments using a multi-level full factorial design, reducing the total number of experimental runs required while still capturing the interactions and effects of the different factors involved. The characterization investigation was carried out using X-ray diffractometry (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and Brunauer–Emmett–Teller (BET). The optimal conditions achieved a composite desirability of 0.9872, indicating a near-ideal balance for both responses. For COD removal, the maximum rate of 98.3721% was achieved under the optimal conditions with <i>Phragmites australis</i> biochar (Adsorbent Material 2), UASB effluent (Wastewater Type 2), a contact time of 90 min, and a dose of 6.5 g/L, yielding a desirability value of 0.97463. The maximum rate of 86.6766% for phenol removal was also attained under the same optimal conditions, yielding a desirability value of 1.0000, representing perfect optimization for phenol removal. A Life Cycle Assessment (LCA) was conducted to evaluate the environmental impacts associated with the treatment of UASB effluent and Arma wastewater using the three different adsorbent materials. The <i>Phragmites australis</i> biochar offers the most environmentally sustainable option for wastewater treatment. It significantly reduces greenhouse gas emissions, resource depletion, toxicity impacts, and energy use compared to Activated Carbon and Chitosan. This research is consistent with the United Nations Sustainable Development Goals (SDGs), namely SDG 6 (Clean Water and Sanitation) and SDG 12 (Responsible Consumption and Production).

The sensor's sensitivity to varying concentrations of lead (II) ions is explored using UV–visible spectroscopy, with pH-adjusted dye solutions in acidic, neutral, and basic conditions. Both Eriochrome Black T and Bromothymol Blue dyes exhibited distinct colorimetric responses to the presence of lead (II), with optimal detection occurring in neutral pH environment. A concentration range of 60–140 ppm of lead (II) ions was examined, and the detection limits were lowest for Bromothymol Blue dye, found to be around 6 ppm. Furthermore, the selectivity of the dyes was tested against other metal ions, showing high specificity for lead (II) ions. The sensor's stability was verified across a temperature range of 25–90 °C. Finally, a paper-based chemo sensor was fabricated to demonstrate the sensor's real-time applicability, where visual color changes confirmed lead (II) detection in water.
