Granular sorbent well suited for adsorbing non-aqueous liquid, preferably oil, with a preferred granular sorbent formed of sorbent granules which preferably are organic and formed of or by organic sorbent starch-containing pellets extruded from a starch-containing admixture. A preferred extruded sorbent pellet preferably is formed with a porous outer surface and a void filled inner starch matrix enhancing adsorption. Extruded sorbent pellets can be treated with sorbent enhancing material and/or coated with another adsorbent, such as smectite, bentonite, producing sorbent granules usable the granular sorbent. In use, liquid soluble material formed in each pellet during extrusion can help adhere together sorbent granules and/or pellets producing a mass or even a clump that is easy to pick up and dispose. In a preferred method, an activating liquid, preferably an aqueous liquid, is applied onto spent granules or pellets to bind them together into such a mass or clump. |
