Zusammenfassung:The Indian government has been pushing for a target of 1.5 billion tonnes of coal production annually by 2020, most of which will be used in the electricity sector. In this context, current issues—status, policies, regulations, and bottlenecks—regarding the disposal of fly ash generated by thermal power plants are examined. Scenarios of ash generation and utilisation are presented. Blending fly ash in cement is the most environmentally sustainable and financially attractive method of its utilisation. Finally, key technical, regulatory, pricing, logistical, and behavioural issues that need to be urgently addressed to reach complete fly ash utilisation are discussed.
