Why Indian Railways is creating a new network for 340 million tonnes of fly ash

📌 Summary:

• The Ministry of Railways is planning a dedicated logistics network to transport nearly 340 million tonnes of fly ash generated annually by thermal power plants across the country
• At present Indian Railways carries only about 13 million tonnes of fly ash a year — a tiny fraction of what is produced — leaving a large evacuation and disposal gap
• Railway Minister Ashwini Vaishnaw chaired a high-level review at Rail Bhawan to plan large-scale fly-ash transport via the rail network
• Fly ash, the largest by-product of thermal (coal) power generation, is both an environmental challenge (needs safe, sustainable management to avoid air/water/soil pollution) and an economic opportunity (a valuable input for cement, bricks, roads and other infrastructure)
• A dedicated rail network would enable bulk, low-cost movement of fly ash from power plants to user industries, supporting safe disposal and resource utilisation

🎯 UPSC Relevance: GS3 Environment — pollution management and circular economy in thermal power; sustainable utilisation of industrial by-products and the logistics/infrastructure dimension.

📝 Prelims Facts:

• ~340 million tonnes of fly ash generated annually; Railways currently moves only ~13 million tonnes/year
• Fly ash is the largest by-product of thermal (coal-based) power generation
• Reviewed by Railway Minister Ashwini Vaishnaw at Rail Bhawan
• Fly ash uses: cement, bricks, road embankments, infrastructure

🔑 Key Term: Fly ash — fine residual particles captured from the flue gases of coal-fired thermal power plants; classified as a notified by-product with mandated utilisation under environmental rules.
