Environmentally friendly animal litter
A method of making an animal litter that includes geopolymerized ash, wherein, the animal litter is made from a quantity of a pozzolanic ash mixed with a sufficient quantity of water and an alkaline activator to initiate a geopolymerization reaction that forms geopolymerized ash. After the geopolymerized ash is formed, it is dried, broken into particulates, and sieved to a desired size. These geopolymerized ash particulates are used to make a non-clumping or clumping animal litter. Odor control may be accomplished with the addition of a urease inhibitor, pH buffer, an odor eliminating agent, and/or fragrance.
1. A method for making animal litter, the method comprising:
providing a quantity of a pozzolanic ash;
mixing the pozzolanic ash with a sufficient quantity of an alkaline activator and water to initiate a geopolymerization reaction and to form a slurry;
drying the slurry to form a geopolymerized ash; and
breaking the geopolymerized ash into particulates.
2. The method of claim 1 , further comprising sieving the particulates of the geopolymerized ash so the particulates have a sieve size between about a −12 sieve and about a +80 sieve.
3. The method of claim 1 , further comprising sieving the particulates of the geopolymerized ash so that the particulates have a sieve size between about a −6 sieve and about a +50 sieve.
4. The method of claim 1 , wherein the alkaline activator is selected from the group consisting of a metal carbonate, a metal silicate, a metal aluminate, a metal sulfate, a metal hydroxide, and mixtures thereof.
5. The method of claim 1 , wherein the sufficient quantity of the alkaline activator comprises between about 0.5 and about 20 grams of the alkaline activator for every 100 grams of pozzolanic ash.
6. The method of claim 1 , wherein the sufficient quantity of the alkaline activator comprises between about 3 and about 12 grams of the alkaline activator for every 100 grams of pozzolanic ash.
7. A method for making animal litter, the method comprising:
providing a quantity of a pozzolanic ash;
mixing the pozzolanic ash with a sufficient quantity of an alkaline activator and water to initiate a geopolymerization reaction and to form a slurry, wherein the alkaline activator is selected from the group consistent of a metal carbonate, a metal silicate, a metal aluminate, a metal sulfate, a metal hydroxide, and mixtures thereof;
drying the slurry to form a geopolymerized ash;
breaking the geopolymerized ash into particulates; and
sieving the particulates of the geopolymerized ash so the particulates have a sieve size between about a −12 sieve and about a +80 sieve.
8. The method of claim 7 , wherein the sufficient quantity of the alkaline activator comprises between about 0.5 and about 20 grams of the alkaline activator for every 100 grams of pozzolanic ash.
9. The method of claim 7 , wherein the sufficient quantity of the alkaline activator comprises between about 3 and about 12 grams of the alkaline activator for every 100 grams of pozzolanic ash.
