Limestone Makes for Cleaner Coal

For older coal-fired power plants this included installing scrubber systems in the smokestacks to filter sulfur from the exhaust. “In 1985, Plains Electric built a power plant in nearby Prewitt, New Mexico and the project manager needed a source for limestone that would pass the qualifications required for the power plant emissions,” he says.
