Definitions
- This invention relates to the elimination of odors from waste material, and more specifically to the eliminatin and control of ammoniacal odors from animal and human excreta.
- the pungent and unpleasant odor of ammonia emanating from organic waste products subject to chemical or microbial degradation is a public nuisance as well as a health hazard, particularly in situations where waste products are left to accumulate over periods of time, such as days, weeks and even months.
- Ammonia is formed as the end product in the degradation of urea by the enzyme urease, and the enzyme degradation of uric acid to form urea, and then ammonia.
- Urea and uric acid are products of protein catabolism. In certain specific environments such as poultry houses, the concentration of ammonia in the air can become so high, that it can cause ammonia blindness in the poultry, thereby causing production losses through the reduced consumption of feed.
- Ammonia fumes in pig farrowing houses can lead to respiratory illness, such as pneumonia, in piglets.
- the odor of ammonia is also a problem in privies, zoological gardens, and sewage treatment facilities.
- the keeping of domesticated pets such as cats, dogs, hamsters, guinea pigs, birds, and the like, where excreta can accumulate in cages, pens or other inhouse facilities also gives rise to objectionable ammonia odors.
- Many efforts have been made to ameliorate the problem of odor emanating from waste materials by the use of certain substances to cover up or "mask" the odor. However, this approach does not remove or eliminate odor, especially the ammonia odor.

- Sodium bisulfate is particularly preferred.
- the concentration of the ammonia control component can vary from about 15 to 100% by weight, preferably from about 20 to 60% by weight of the total composition.
- the liquid or spray composition can also include water as a diluent, varying from about 40 to 85% by weight, preferably 50 to 80% by weight of the total composition.
- a viscosity additive or thickener preferably a natural gum material can also be included to give body to the liquid or spray. These include pectin, xanthan gum, gum arabic, gum tranacanth, locust bean gum, tamarind, and guar gum.
- the natural gum thickener can vary from about 0.25-2% by weight, preferably 0.5 to 1% by weight of the total composition.

- the proportions of ammonia control component to filler material also will vary, depending upon whether the animal will come into direct contract with the composition. When the animal is kept in a cage with openings in the floor which allow the excreta to fall through and collect on a pan or tray containing the ammonia control composition, the animal will not come into contact with the ammonia control composition.
- the proportions of ammonia control component can be increased to the extent that it can be used without filler material in the case of sodium bisulfate.
- the filler material can vary from 0 to 80% by weight, preferably 30 to 70% by weight of the total composition.
- the ammonia control component can vary from 20 to 100% by weight, preferably 30 to 70% by weight of the total composition.
