Weir, KS: Royal Black Granules Plant
McCabe Industrial Mineral's longest-running plant is located in Weir, KS. Built in 1984, the plant has processed over a million and half tons of coal bottom ash. For decades, power plants in the region landfilled their byproduct from processing coal. MIM was on the forefront of finding a use for the slag as a roofing granule and blasting abrasive. The Royal Black Plant has nearly 0% waste as it also produces a finer grade of roofing material for rolled roofing products, an ice melt product for roads and a filler for cement. With the closure of 2 out of 3 powerplants that provided MIM with raw material, the plant has developed a new light headlap granule produced from a silicious limestone quarried in Gravitt, AR. The Royal Black Plant has the ability to ship its products by truck and railcar.
