Abstract
Spent filter media material may be blended with a classic material, such as high-density polyethylene, polypropylene, polybutylene succinate, or polylactic acid, to form a filled plastic composition. The spent filter media may include spent diatomaceous earth, spent perlite, and/or residues thereof. The composition may be performed by co-extruding a mixture of the plastic material and the spent filter media. Surprisingly, the spent filter media may be used as-supplied and without the need to dry the material. The resulting plastic composite material has numerous uses, including, for example, litter scoops and eating utensils.
