Claims (34)

1. A compressed absorbent tablet comprising:

an approximately 7.5 mm diameter by 3 mm thick tablet of a pre-dried coir pith with particle sizes between 2 mm to 4 mm and a pre-compression moisture content of below 15% and no added moisture, and the compressed absorbent tablet having a 5:1 to 9:1 compression ratio.

2. The compressed absorbent tablet of claim 1 , wherein the coir pith has coir fibers removed.

3. A method of making the compressed absorbent tablet of claim 1 comprising:

drying a volume of uncompressed coir pith with a 2 mm to 4 mm length to a moisture content of below 15%; and

compressing a portion of the volume of uncompressed coir pith with the moisture content of below 15% and particle sizes between 2 mm to 4 mm length into a tablet having an approximately 7.5 mm diameter by 3 mm thickness and a 5:1 to 9:1 compression ratio;

wherein no moisture is added to the uncompressed coir pith either before or after being dried to have the moisture content of below 15% and the tablet is not dried after being compressed.

4. The method of claim 3 further comprising:

removing coir fibers from the uncompressed coir pith before compressing the tablet.

5. The method of claim 4 further comprising:

simultaneously compressing a plurality of tablets in a fixed die with a plurality of holes formed there through.

6. The method of claim 5 wherein the simultaneously compressing the plurality of tablets in the fixed die with the plurality of holes formed there through further comprises:

simultaneously compressing the plurality of tablets in the fixed die with the plurality of holes formed there through using a moveable punch with a plurality of pins each reciprocally-shaped and spaced on the moveable punch to enter the plurality of holes in the fixed die.

7. The method of claim 3 further comprises:

compressing each tablet with an approximately 110 ton load.

8. The method of claim 7 further comprises:

compressing each tablet with the approximately 110 ton load for approximately 15 seconds.

9. A compressed absorbent tablet comprising:

an approximately 3 mm thick tablet of a pre-dried coir pith with particle sizes between 2 mm to 4 mm and a pre-compression moisture content of below 15% and no added moisture, and the compressed absorbent tablet having a 5:1 to 9:1 compression ratio.

10. The compressed absorbent tablet of claim 9 , wherein the coir pith has coir fibers removed.

11. A method of making the compressed absorbent tablet of claim 9 comprising:

drying a volume of uncompressed coir pith with a 2 mm to 4 mm length to a moisture content of below 15%; and

compressing a portion of the volume of uncompressed coir pith with the moisture content of below 15% and particle sizes between 2 mm to 4 mm length into a tablet having an approximately 7.5 mm diameter by 3 mm thickness and a 5:1 to 9:1 compression ratio;

wherein no moisture is added to the uncompressed coir pith either before or after being dried to have the moisture content of below 15% and the tablet is not dried after being compressed.

12. The method of claim 11 further comprising:

removing coir fibers from the uncompressed coir pith before compressing the tablet.

13. The method of claim 12 further comprising:

simultaneously compressing a plurality of tablets in a fixed die with a plurality of holes formed there through.

14. The method of claim 13 wherein the simultaneously compressing the plurality of tablets in the fixed die with the plurality of holes formed there through further comprises:

simultaneously compressing the plurality of tablets in the fixed die with the plurality of holes formed there through using a moveable punch with a plurality of pins each reciprocally-shaped and spaced on the moveable punch to enter the plurality of holes in the fixed die.

15. The method of claim 11 further comprises:

compressing each tablet with an approximately 110 ton load.

16. The method of claim 15 further comprises:

compressing each tablet with the approximately 110 ton load for approximately 15 seconds.
