Abstract

An animal litter composition that includes geopolymerized ash particulates having a network of repeating aluminum-silicon units is described herein. Generally, the animal litter is made from a quantity of a pozzolanic ash mixed with an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. This geopolymerization reaction may occur within a pelletizer. After the geopolymerized ash is formed, it may be dried and sieved to a desired size. These geopolymerized ash particulates may be used to make a non-clumping or clumping animal litter or other absorbing material. Aluminum sulfate, clinoptilolite, silica gel, sodium alginate and mineral oil may be added as additional ingredients.

Claims (14)

1. An animal litter composition comprising:

geopolymerized ash particulates having a network of repeating aluminum-silicon units, wherein the geopolymerized ash particulates have a sieve size that is between about a 50 sieve and a −6 sieve, wherein the geopolymerized ash particulates are formed from a pozzolanic ask wherein the geopolymerized ash particulates have been dried.

2. The animal litter composition as in claim 1 , further comprising:

between about 0 and about 10 wt % aluminum sulfate;

between about 0 and about 2 wt % clinoptilolite;

between about 0 and about 6 wt % silica gel;

between about 0 and about 5 wt % sodium alginate; and

between about 0 and about 10 wt % mineral oil.

3. The animal litter composition as in claim 2 , comprising:

about 7 wt % aluminum sulfate;

about 5 wt % clinoptilolite;

about 2 wt % of silica gel;

about 1.5 wt % sodium alginate; and

about 1 wt % mineral oil.
