## Abstract

A composite ash produced by thermally processing paper and/or carpet exothermic processing waste, the composite ash being an inorganic mineral product or oxidized material of common crystalline and amorphous non-crystalline composition comprising metakaolin and at least one of a group consisting of mineral oxide and mineral carbonate, the composite ash being reactive with a pH greater than about 7.0.

## Claims

### Claim 1

A composite ash produced by thermally processing paper and/or carpet exothermic processing waste, the composite ash being an inorganic mineral product or oxidized material of common crystalline and amorphous non-crystalline composition comprising metakaolin and at least one of a group consisting of mineral oxide and mineral carbonate, wherein the composite ash is reactive with a pH greater than about 7.0, wherein the composite ash is used as a geopolymer precursor for manufacturing a post-consumer or post-industrial product from an aqueous waste stream, and wherein the geopolymer precursor is used as a capture platform and precipitation agent in the aqueous waste stream.

### Claim 2

A composite ash produced by thermally processing paper and/or carpet exothermic processing waste, the composite ash being an inorganic mineral product or oxidized material of common crystalline and amorphous non-crystalline composition comprising metakaolin and at least one of a group consisting of mineral oxide and mineral carbonate, wherein the composite ash is reactive with a pH greater than about 7.0, wherein the common crystalline and amorphous non-crystalline composition is alterable through at least one of a group consisting of (1) an exothermic-processing-waste composition variation, (2) a thermal-processing temperature variation, and (3) a thermal-processing pressure variation;
whereby the spatial orientation of the atoms within the common crystalline and amorphous non-crystalline composition are altered resulting in changes in bond length or bond angle or a combination, to customize the reactivity of the composite ash.
