“…Sewage sludge management can also include landfilling or utilisation for disposal (Arina & Bendere, 2011). The literature review in this field focuses on the evaluation of various types of sewage sludge storage technologies, such as landfill or compost storage (Bagheri et al, 2023;Grgas et al, 2023). Research also includes evaluating environmental aspects such as greenhouse gas emissions groundwater pollution, and reducing the potential impact on human health and ecosystems (Janas et al, 2018).…”

The purpose of the article is to demonstrate practices used to supervise the use of sewage sludge for agricultural purposes. The presented research and conclusions are a trend analysis and are not to be used to penalise entities. Sewage sludge, which comes from the illegal dumping of wastewater into municipal wastewater by industrial plants, contains large amounts of heavy metals. Treatment plants transfer the sludge for agricultural use. Regulations specifically restrict the mode and conditions for such use of sludge. Methods: the research was carried out using a proprietary questionnaire, which is a supplement to the reporting questionnaire of the National Urban Wastewater Treatment Program implemented by the State Water Company "Wody Polskie". Results: The survey was conducted at 208 wastewater treatment plants in Poland. The results show that the majority of wastewater treatment plants do not properly supervise the process of introducing sewage sludge into the soil. They also lack supervision of how much heavy metals from wastewater are introduced into the soil. This means that there is a very high risk of contamination of agricultural soils. The results obtained could initiate a detailed analysis of this phenomenon in Poland. A comprehensive study of the scale of the practice and its current effects is required to determine the actual condition of soil treated with sewage sludge.

“…Furthermore, the negative consequences of chemical or inorganic farming practices extend beyond soil quality to the water quality of the Ganga River. Runoff from agricultural lands laden with chemical fertilizers and pesticides contaminates the river, posing threats to both aquatic life and human health (Bagheri et al, 2023;Balkrishna et al, 2024). Excessive of chemical fertilizer application due to population growth on soil health in the Ganges River basin, depletion in the water, exacerbating ecological imbalances (DebRoy et al, 2012; Khot et al, 2021).…”

To assess the viability of organic farming by analyzing various characteristics, 26 soil samples were gathered from five states in three Indo-Gangetic regions for the current study. With a median pH of 6.7 and electrical conductivity ranging from 85.27 µs/cm to 425.63 µs/cm, the sites from Upper Ganga Region (UGR) showed favorable soil conditions, leading to higher Soil Quality Index values (0.68 to 0.75; p < 0.05). On the other hand, the Lower Ganga Region (LGR) exhibited neutral to slightly alkaline pH of 7.7, greater EC levels (421.89 µs/cm to 690.75 µs/cm), and lower SQI values (0.55 to 0.62; p < 0.05). The UGR had the highest nitrogen levels (153.87 kg/ha to 172.64 kg/ha; p < 0.05), while the Middle Ganga Region (MGR) had higher amounts of phosphorus (18.76 kg/ha to 24.59 kg/ha; p < 0.05) and potassium (204.15 kg/ha to 235.78 kg/ha). The amounts of each nutrient varied widely. The LGR exhibited higher levels of zinc (range: 48.26 mg/kg to 55.94 mg/kg) and lead (6.25 mg/kg to 8.31 mg/kg; p < 0.05) in comparison to the UGR and MGR, however the concentrations of heavy metals varied. In conclusion, organic farming is feasible along the Ganga basin region; however, because of its favorable soil conditions and higher SQI values, the UGR may be a better location for it, while the MGR & LGR might need more intensive soil management techniques to reduce the risk of contamination and promote sustainable organic farming practices.

“…Significant quantities of wastewater sludge are generated globally every year, varying from approximately 5 g to 90 g of dry material per capita per day [1]. As reported in the literature [2], global dry sewage sludge production reached 45 million tons in 2017, and forecasting suggests that sewage sludge production will increase in the next few years due to both the rapid growth of the population and the fast rate of urbanization.…”

An innovative process layout for sludge waste management based on chemical looping combustion and flue gas methanation is analyzed in this work. The technical performance of the system was assessed by considering that the flue gas is first purified and then mixed with a pure hydrogen stream sourced from an array of electrolysis cells to produce methane. The life cycle assessment (LCA) and life cycle cost (LCC) methodologies were applied to quantify the environmental and economic performances of the proposed process, and a hotspot analysis was carried out to recognize its most critical steps. The proposed system was then compared with a reference system that includes both the conventional waste management pathways for the Italian context and methane production. Finally, to account for the variability in the future economic climate, the effects of changes in landfill storage costs on sewage end-of-life costs for both the proposed and reference systems were evaluated. With respect to 1 kg/h of sewage sludge with 10%wt of humidity, the analysis shows that the proposed system (i) reduces landfill wastes by about 68%, (ii) has an end-of-life cost of 1.75 EUR∙kg−1, and (iii) is environmentally preferable to conventional sewage sludge treatment technologies with respect to several impact categories.
