Rock dust is a byproduct of the quarrying industry and results from rock crushing. In the industry it is known as blue metal, cracker or crusher dust. Landscapers use rock dust for filling holes, bedding paving stones and mixing with cement. More recently its applications have broadened to other areas and its true importance is becoming apparent.

Many types of crushed stone: Crushed stone is not a "standardized commodity." It is made by mining one of several types of rock such as limestone, granite, trap rock, scoria, basalt, dolomite, or sandstone; crushing the rock; and then screening the crushed rock to sizes that are suitable for the intended end use.

Adding rock dust to agricultural lands speeds up the chemical reactions that lock carbon up — for thousands of years — in soil. If applied to croplands globally, rock dust could theoretically help suck an estimated 2 to 4 billion tons of carbon dioxide from the air every year, between 34 and 68 percent of the global greenhouse gas emissions ...
