Abstract
The present invention provides an improved method for sorbing aqueous fluids through the use of a biodegradable, clumping, low odor, low attrition, low swelling ground grain litter. The ground grain litter is composed of a ground grain selected such that when the ground grain is wetted it tends to swell in volume less than 50-100%. In a preferred embodiment, the ground grain litter comprises ground hard red spring wheat used to sorb pet urine and fecal liquids voided by a pet into the litter.
Claims9
A method for sorbing an aqueous liquid utilizing a ground wheat grain litter, said method comprising the step of:
- (a) situating a ground wheat grain litter to be contacted by an aqueous liquid to be sorbed,
- wherein said ground wheat grain litter consists essentially of a ground whole wheat grain.
A method for sorbing an aqueous liquid utilizing a ground wheat grain litter, said method comprising the steps of:
- (a) selecting a whole wheat grain;
- (b) grinding said whole wheat grain;
- (c) providing 30% to 100% by weight of the ground wheat grain ground in step (b) in a ground wheat grain litter;
- (d) situating the ground grain litter of step (c) to be contacted by an aqueous liquid to be sorbed;
- wherein said ground grain litter does not include an added gluten based media and said ground grain litter does not include added grain flour.
A method for sorbing an aqueous liquid utilizing a ground wheat grain litter, said method comprising the steps of:
- (a) selecting a whole hard red spring wheat grain;
- (b) grinding said whole hard red spring wheat grain, in a mill, at 10-17% moisture, such that after grinding at least 75% of the ground grain consists of particles in a range of 250-2500 microns in size;
- (c) providing 50-100% by weight of the ground wheat grain of step (b) in a ground grain litter;
- and
- (d) situating the ground grain litter of step (c) to be contacted by a aqueous liquid to be sorbed;
- wherein said ground wheat grain litter does not include an added gluten based media and said ground grain litter does not include added grain flour.
