“…CHAP was able to attain a removal efficiency as high as 94% at an initial Cd(II) concentration of 80 mg/L. Barot and Bagla et al [194] came up with a green and clean alternative for Cd(II) removal from wastewater. They prepared an adsorbent ''dry cow dung powder'' (DCP) which showed 85% removal efficiency within 10 minutes contact time at 4500 rpm agitation speed with a dose of 100 mg DCP.…”

“…The cowdung has been used successfully in previous studies for industrial wastewater treatment for combating heavy metals, pharmaceuticals, pesticides, and petrochemicals [28][29][30][31][32]. cowdung harbors a rich microbial diversity, containing different bacteria, protozoa, and yeast.…”

“…Even cow dung ash has been found active in water disinfection [42]. The dried powder form of cow dung is also helpful as a green adsorbent material to remove carcinogenic and heavy metal water pollutants [28,43]. FAO, 1998 mentioned that cow dung and cow urine possess complex degrading substances [44].…”

The present research study was performed to find a solution for the mitigation of ammonia nitrogen in municipally treated sewage effluent (MTSE) using two natural bio-resources. One was composted cow-dung sludge that had catalytic enzymes and nitrifying bacterial mass, and the second was Yucca extract (a desert plant). MTSE samples put in one-liter beakers/ jars having initial ammonia nitrogen content of 34.78 mg/L, when treated with 0.0 g/L (control Sample), 1 g/L, 5 g/L (cow dung) and 10 mg/L, 50 mg/L (Yucca extract), respectively, reported depletion of ammonia nitrogen to about 0.00 mg/L ammonia (NH3) as N. It (NH3) transformed to 17.8, 0.18, 0.09, 18.65, and 18.85 mg/L nitrite asN. Ammonia converted to 21.8, 110.1, 133.5, 20.5, 20.8 mg/L nitrate asNO3, respectively. After eight days of treatment, the jar test apparatus reported the results at 35 rounds per minute (RPM) and a temperature of 32°C. It was found that digested cowdung acted catalytically in eliminating the ammonia nitrogen by converting it to nitrate in a short period of nearly eight days, leading to almost 100% ammonia conversion.

“…The research work of Bagla et al, has examined and justified an innovative and concrete role of DCP in the bioremediation of toxic metal pollutants and hazardous radionuclides from the pool of various effluents using Radiotracer technique. Notable heavy metal pollutants like trivalent and hexavalent chromium, cadmium [39], mercury [40], silver [41], zinc [42] have been eliminated from aqueous systems using DCP as a biosorbent. Similarly, radionuclides commonly found in radioactive waste - 60 Co, 90 Sr and 137 Cs [43,44], have been removed from simulated systems of reactor and reprocessing waste.…”

Water-Food-Energy (WFE) Nexus regulates biosphere and irrespective of alphabetical or chronological order, it must have synergy for the sustainability of life. Population, Pollution and current Pandemic- COVID has made it vivid to entire scientific community that unless we strengthen this trio, our progressive humanity is sure to collapse. Humic Substances (HS), the originator of the life has promising utilization in almost every sectors of life, reinforcing WFE Nexus. This chapter dedicates to novel unearthed HS, Dry Cowdung Powder (DCP) and its unique contribution in sustaining the triangle of life, WFE. DCP has been employed as humiresin for bioremediation of wastewater containing heavy metals and radionuclides. The known candidate for Biorhexistasy, DCP increases soil fertility, minimizes erosion and acidification. It is also extensively explored as biofuel, green and clean source of energy. ‘Nothing of Nature is a Waste’ and ‘Waste is a Commodity’ aptly describes DCP, the sustainer of WFE Nexus.
