Jack Johnson - Waseca MN, US

International Classification:

A01K029/00

US Classification:

119/171000

Abstract:

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 50% by weight wood particles and 50% to 99% by weight ground grain. The sorbency of a ground grain litter can be improved by pelletization and crumbling. Addition of up to 50% of wood particles to a ground grain litter further enhances the sorbency while maintaining suitable swelling and clumping characteristics.

Abstract:

A species of bean, L. , is pelleted, crumbled and sieved to a desired size. A sorbent produced therefrom has excellent sorbency and clumping, and is consequently well-suited for application as a scoopable animal litter. Alternative applications include, but are not limited to, industrial, commercial and residential sorbents, and high nitrogen content tackifiers suitable for hydro-seeding and other application.
