A slightly puffed, low density, moisture-adsorbing and odor-absorbing additive that can readily remove undesirable odors from a confined space is produced from re-purposed spent carbon materials obtained from other processes. The product is particularly suitable as an addition to animal litters and the like with possible uses in human applications. An aspect of the method includes a step of extruding a spent carbon mixture, optionally containing diatomaceous earth to obtain the additive. Also disclosed are de-germinated corn flour, of grits, that aid process flow and can serve as a substrate for the spent carbon materials.
