Clumped sorbent material
The present invention pertains to a natural product litter composition as well as methods of preparing and using a natural product litter as a sorbent for liquids. The sorbent contains 1 to 10% by weight Aspen particles and 90 to 99% by weight ground grain byproducts including red dog wheat and wheat middlings. The sorbency of a ground grain litter can be improved by pelletization and crumbling.
1. A sorbent composition for sorbing a liquid, the sorbent comprising a pellet or crumpled pellet comprising:
(a) ground grain byproducts including 25% by weight wheat middlings and 65 to 74% by weight red dog wheat; and
(b) 1 to 10% by weight of Aspen particles, said sorbent swelling less than about 10% based on the volume of the sorbent when sorbing a maximum amount of liquid.
2. The sorbent composition of claim 1 , wherein the Aspen particles sorb an amount of liquid based on weight between about 0.5 times to about 5 times the weight of the Aspen particles.
3. The sorbent composition of claim 1 , wherein the ground grain byproducts is prepared from hard red spring wheat.
4. The sorbent composition of claim 1 , wherein the sorbent comprises about 1% by weight Aspen particles.
5. The sorbent of claim 1 , wherein the sorbent can sorb an amount of liquid based on weight equal to about 0.5 times to about 5 times the weight of the sorbent.
6. The sorbent composition of claim 1 , wherein the sorbent clumps upon contact with the liquid.
7. The sorbent composition of claim 1 including 8% Aspen particles and the ground grain by products include 67% red dog wheat.
8. The sorbent composition of claim 1 including 1% Aspen particles and the ground grain by products include 74% red dog wheat.
9. A particulate sorbent comprising a homogeneous mixture, about 1 to about 10% by weight ground Aspen particles and ground grain byproducts including 25% by weight wheat middlings and 65 to 74% by weight red dog wheat, said sorbent swelling less than about 10% based on the volume of the sorbent when sorbing a maximum amount of liquid.
10. The particulate sorbent of claim 9 that contains about 1% by weight Aspen particles.
11. The particulate sorbent of claim 9 that has no volume change on sorbing a maximum amount of liquid.
