Example waste disposal substrates include multiple nonwoven layers comprising activated carbon, superabsorbent particles, and optionally fibers. The substrate may comprise from two to eight nonwoven layers, including at least one layer containing activated carbon in combination with fibers and at least one layer containing activated carbon without fibers. At least one layer may contain a mixture of activated carbon and superabsorbent particles. In representative constructions, the substrate includes two outermost nonwoven layers, two nonwoven layers containing activated carbon positioned inward of the outermost layers, two layers containing a mixture of activated carbon and superabsorbent particles positioned inward of the activated-carbon layers, and two interior nonwoven layers positioned between the mixture layers. The layered arrangement provides an integrated structure containing activated carbon and superabsorbent particles in selected combinations of nonwoven layers.
