1. A multicomponent granular absorbent blend comprising:
(a) a dust-containing or dust-forming blend component comprised of a plurality of pairs of dust-containing or dust-forming liquid-absorbent granules each composed of one of a dust-containing liquid-absorbent material and a dust-forming liquid-absorbent material, each dust-containing or dust-forming liquid-absorbent granule comprised of a plurality of smaller dust particles which can become airborne; and
(b) a dust-suppressing blend component comprised of a plurality of pairs of dust-adhering liquid-absorbent granules, each dust-adhering liquid-absorbent granule in the form of an extruded pellet consisting essentially of a starch-containing organic material and containing a water-soluble binder formed of or from starch during pellet extrusion in an amount sufficient to form a clump of the dust-adhering liquid-absorbent pellets and the dust-containing or dust-forming liquid-absorbent granules when wetted with water or a liquid comprised of water.
