Abstract
ABSTRACT OF THE DISCLOSURE A method is disclosed of manufacturing an oil absorbing material by introducing waxed cardboard into a hammer mill to produce a fluffy hydrophobic and/or hydrophillic cellulosic material having the wax distributed throughout fluffy cellulose fibers, and the material produced thereby. Also disclosed is a method of producing kitty litter by introducing a mixture of curtain coated waxed cardboard and paper into a hammer mill and thereafter forming the product from the hammer mill into a dense solid, and the product produced thereby. Pellets and briquettes are disclosed.

Claims (16)
1. A method of manufacturing an oil absorbing material comprising introducing waxed cardboard into a hammer mill to produce a fluffy hydrophobic cellulosic material having the wax distributed throughout fluffy cellulose fibers.
2. The method of claim 1, wherein the material is forced through a screen before leaving the hammer mill.
3. The method of claim 1, wherein at least some of the cardboard is torn or cut before introduction to the hammer mill.
4. The method of claim 1, wherein the waxed cardboard is introduced into successive hammer mills and forced through a 3/8" screen before exiting the final hammer mill.
5. A hydrophobic cellulosic material comprised of cellulose fibers having wax distributed throughout produced by introducing waxed cardboard into a hammer mill.
6. The hydrophobic cellulosic material claim 5, wherein at least some of the waxed cardboard is curtain coated on at least one side.
7. The hydrophobic cellulosic material of claim 5, wherein at least some of the waxed cardboard is wax saturated.
8. A method of producing kitty litter, comprising introducing a mixture of curtain coated waxed cardboard and paper into a hammer mill and thereafter forming the product from the hammer mill into a dense solid.
9. A method of claim 8, wherein the curtain coated cardboard is present in an amount not less than about 1% by weight.
10. The method of claim 8, wherein the curtain coated cardboard is present in an amount of about 5% by weight.
11. The method of claim 8, wherein the mixture of waxed cardboard and paper is introduced into successive hammer mills.
12. The method of claim 8, wherein the product from the hammer mill is forced through a screen before being formed into a dense solid.
13. A kitty litter material comprised of dense solids produced by introducing a mixture comprising paper and curtain coated waxed cardboard into a hammer mill and compacting the product therefrom into a dense solid.
14. The kitty litter material of claim 13, wherein the curtain coated waxed cardboard is present in an amount not less than about 1% by weight.
15. The kitty litter material of claim 13, wherein the curtain coated cardboard is present in an amount of about 5% by weight.
16. The kitty litter material of claim 15, wherein the material is produced by introducing the mixture into successive hammer mills and the product from the second hammer mill is forced through a screen, and wherein the screened material is formed into a dense solid pellet by extruding.
