A cellulose-based granule that functions as a carrier vehicle for an odor control agent is described. The granule has a relatively porous substrate body having a high-surface area of at least about 200 m2/gram, and metal-modified silica particles either adhered to or encapsulated within the cellulose-based substrate. Each of the metal-modified particles has adsorbed metallic ions that are adapted to bind a molecule of a gaseous compound, an odorous compound, or combinations thereof. The odor control granule is free-flowing (i.e., do not exhibit a tendency to agglomerate to each other) and exhibit powder-like characteristics, wherein the granules have an average powder density of 30 to 600 g/l according to DIN 53,468.
