Instead of disposing them in landfills, it can be best utilized as partial replacement to sand. In crusher dust, the particles (% finer than 150 microns) are generally high, a major concern limiting its percentage replacement to minimum with sand in a concrete mix. It can be replaced to the amount 25%. Its Availability is not a concern.
