In a proactive move towards environmental stewardship and resource utilization, the Ministry of Coal (MoC) has intensified efforts to manage fly ash generated by thermal power plants. This byproduct of coal combustion, traditionally considered a waste material, is being repurposed and utilized in various constructive applications, thereby minimizing environmental impact and contributing to sustainable development practices.
Key Initiatives and Achievements:
1. Allocating Mine Voids for Fly Ash Disposal: The MoC has allocated mine voids for properly disposing of fly ash, addressing environmental concerns associated with its storage. A Central level Working Group (CLWG) oversees the allocation process, ensuring transparency and efficiency. As of now, 19 mines have been allocated to 13 Thermal Power Plants (TPPs), facilitating the safe disposal of fly ash.
2. Repurposing Fly Ash for Construction: Extensive research and development efforts have enhanced the utilization of fly ash in construction materials, such as filling voids and manufacturing bricks and tiles. This not only reduces the environmental footprint of coal-based power generation but also conserves natural resources and supports sustainable development goals.
3. Centralized Management Portal: To streamline operations and enhance transparency, the MoC, in collaboration with the Central Mine Planning and Design Institute (CMPDI), is developing a centralized portal. This platform will facilitate the application process for TPPs seeking mine voids for fly ash disposal, ensuring efficient management and compliance with regulatory guidelines.
4. Feasibility Studies and Standard Operating Procedures (SoPs): Feasibility studies are ongoing to optimize the mixing of fly ash with overburden in operational mines, guided by established Standard Operating Procedures (SoPs). These studies, including a significant initiative at the Nigahi operational mine, aim to determine the best practices for safe and effective fly ash utilization.
5. Environmental and Safety Measures: The MoC emphasizes the safe handling and management of fly ash to mitigate environmental concerns, including the leaching of heavy metals and emissions of fine particles. Collaborative efforts with regulatory bodies and industry stakeholders ensure adherence to stringent environmental standards and promote sustainable practices.
Through these initiatives, the Ministry of Coal continues to lead India towards a cleaner and greener future, leveraging fly ash as a valuable resource rather than a waste product. By fostering collaboration and innovation in fly ash management, the MoC aims to achieve optimal environmental outcomes and sustainable development in the energy sector.
