Karnataka looks for tech that will re-purpose thermal plant residue

Raichur Thermal Power Station (RTPS) may be staring at a major environmental crisis. Fly-ash, the easily airborne byproduct of coal combustion, produced at the state's largest thermal power plant, was until now being carefully stockpiled in its backyard; but running out of space, the energy department is now looking to import technology from Germany to clear up the stock, scientifically. The idea is to adopt a feasible scientific method to cope with similar challenges at new thermal plants in Ballari and Raichur.
