A Critical Examination of the Potential Applications of Flyash in Several Industries: Especially the Use of Flyash in Agriculture Sector

Mohd Wasi Baig

Abstract: Disposing of solid waste produced through various sources is an emerging problem worldwide. Flyash, a form of solid waste from thermal power plants, involves a massive amount of water, energy, and land area ash ponds for disposal. This industrial waste removal has raised an increased energy demand along with various environmental, economic, and social problems, and it is rising globally. Its production from the coal - based thermal power plant is about 160 million tons annually which is expected to rise to 600 million tons by 2030, according to the current ENVIS CSIR report. It is an alarming situation that demands an avid generation of strategies for properly managing fly ash. Recent research has shown that this waste can be salvaged as a potential resource material in agriculture. A comprehensive review of numerous studies has been reported in this study, which systematically covers the importance, scope, and apprehensions regarding flyash utilization in different sectors. Further, some studies also report some established solutions to handle the problems of radioactivity and heavy metal content in flyash, but still, long - term confirmatory research and demonstration are necessary. This review also identified the helpful utilization of flyash in agriculture. The countries like India monitoring soil health, crop quality is a significant concern for farmers. Agricultural lime application contributes to global warming as the Intergovernmental Panel on Climate Change (IPCC) assumes that all the carbon in agricultural lime is finally released as CO2 to the atmosphere. It is expected that using flyash instead of lime in agriculture can reduce net CO2 emissions and will reduce global warming too. Hence, the importance of flyash of crop health monitoring is highlighted.
