“…The increasing reliance on agricultural wastewater encounters a notable obstacle due to its dependency on either untreated wastewater or polluted river and streams.Limited availability and high costs of freshwater, coupled with inadequate wastewater treatment infrastructure to accommodate urban growth, leave urban farmers with little choice but to use highly contaminated water for their agricultural needs [3,4]. This scenario presents a particularly tough challenge for urban communities with limited financial resources, as they heavily rely on agriculture for their income, employment, and food security.…”

The present study was carried out on characterization of municipal sewage water tank of Manchalapur village near Raichur city in Karnataka. The water samples were collectedeight times from four different locations like inlet, outlet and water spreading area of the Manchalapur tank during the year 2018-2019 in monsoon and post monsoon season. The collected water samples were analyzed for the water quality parameters by using standard procedure. The results obtained were compared with Central Pollution Control Board (CPCB) and Bureau of India Standards (IS 2296:1992) water quality requirements for irrigation. The results showed that pH (7.89, 8.54), Electrical Conductivity (1.41, 1.48 dSm-1), Total Dissolved Solids (929.63, 1031.56 mg L-1), Carbonate (2.15, 0.86 mg L-1), Bicarbonate (7.71,4.99 mg L-1), Nitrate (26.90, 34.09 mg L-1), Phosphate (9.85, 6.20 mg L-1), Calcium (3.38, 2.77 mg L-1), magnesium (5.16, 4.13 mg L-1), Sodium (0.85, 0.92 mg L-1), Biological Oxygen Demand (1396.88, 1252.31 mg L-1), Chemical Oxygen Demand (14480, 8573.0 mg L-1), Dissolved Oxygen (7.91, 8.02 mg L-1) and turbidity (13.33, 8.77 NTU) for monsoon and post monsoon respectively. All the water quality parameters were within the recommended range of irrigation standards except the parameters BOD, COD, DO and turbidity. The results could be applicable advice to farmers and agricultural researchers for proper management and use of tank water for agricultural purpose.

“…Nevertheless, it should be noted here that the amount of certain chemical compounds contained in fly ash prevents its use in this way. The pretreatment of these compounds is required, which does not necessarily involve a large financial investment [6].…”

The purpose of the article was to conduct an in-depth literature review on the possibilities of managing combustion by-products (mainly fly ash) in the context of a closed-loop economy. First, information on the chemical composition of fly ash in Poland was collected and compared with the composition of fly ash in other European countries. The authors concentrated on describing methods for synthesizing geopolymers and zeolites using fly ash as a substrate. By-products of zeolite synthesis, which are strongly alkaline solutions, can be used as a substrate in the synthesis of geopolymers. A concept has been proposed to combine the synthesis of zeolites and geopolymers into a single process to close the material loop. The search for comprehensive technological solutions that take into account the ideas of a closed-loop economy is essential in an era of resource depletion, and this literature review encapsulates this topic area.
