REVIEW ON PRODUCTION AND UTILIZATION OF FLY ASH: AN INDIAN PERSPECTIVE

Abstract

A rapidly developing economy creates surge in energy demand and forced to find various alternative energy sources. Though many non-conventional energy sources have come up in the energy landscape, the t dependency on coal-based energy has not been reduced. Continuous coal burning generates huge quantity of Fly Ash and creates problems of storage, transportation, and management for power plants. If the fly ash generated is not handled properly, it poses a serious threat to ecology and the environment. The present study begins with focusing on the importance of coal in the Indian energy sector and discuss the status of fly ash generation and utilization throughout the years. It also focuses on how enforced laws and regulations help for management of fly ash. It emphasizes fly ash classification and physical-chemical characteristics, then, elaborates on the different sectors that have adopted fly ash as resource material and proven its worth over a time. This review attempts to highlight the current status of fly ash management in India which contributes to environmental and natural resources conservation.
