Description
53~56 ¦ ELIMI~ATION OF ODORS FROM WASTE r~ATERIAL
BACKGROUND OF THE INVENTION
I l. Field Of The Invention I . .
¦ This invention relates to the elimination of odors from 5 ¦ waste material, and more specifically to the elimination and I ,. . . . ... . . .. _. -control of ammoniacal odors from animal and hurnan 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 1 acid to form urea, and then arnmonia. Urea and uric acid are 20 ¦ 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 1 consumption of feed.
25 ¦ A~monia fumes in pig farrowing houses can lead to respiratory ¦ illness, such as pneumonia, in piglets. The odor of ammorlia is ¦ also a problem in privies, zoological gardens, and sewage treat-¦ ment 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 in-house facilities also 1153~56 gi s rise to objectionable an~nonia 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. Other methods have dealt with controlling different odors associated with the decay of fecal and other waste materials, such as mercaptans, dialkylsulfides, hydrogen sulfide and skatole These methods have not been successful in controlling or elimina-ting ammonia odors emanating from the waste materials.

Bactericides such as 6-ethoxy -1,2-dihydro-2,2,4-trimethylquinollne have also 1153~
been used, but they are not effective. The state of the art approaches generally seek to deal with all odors emanating from animal and human waste materials, and, in so doing, do not successfully deal with the problem of controlling and eliminating ammonia odor.
SU~MARY OF THE INVENTIO~
In accordance with the present invention, the problem of ammonia odor emanating from waste materials is eliminated and controlled by contacting the waste material with a composition containing a deodorizing ~gent which produces a non-odorous ammonium salt, thereby eliminating gaseous ammonia from evolving into the air. The present invention also eliminates additional odors resulting from putrefaction due to ammonia fixing bacteria.
DETAILED DESCRIPTION OF THE INVENTIOI~
The odor control composition of the present invention utilizes monobasic salts of dibasic acids and monobasic or dibasic salts of tribasic acids, etc. and mono-, or di-, or tri- etc. basic acids, as the ammonia control agent. These include the oxo acids of sulfur and phosphorus, alkali metal monobasic salts of the 20 ¦ oxo acids of sulfur, dibasic salts of the oxo acids of phosphorus ~ and alkaline earth dibasic salts of the oxo acids of sulfur and 1153~56 phosphorus .
It has been found that for the aforesaid sub-stances to be operable as ammonia control agents the value of their dissociation constant, pXa, should be less than the dissociation constant of aqueous ammonia. The dis-sociation constant, also referred to as the equilibrium constant is the product of the concentrations (or activities) of the substances produced at equilibrium in a chemical reaction dividèd by the product of concentrations of the reacting substances, each concentration raised to that power which is the coefficient of the substance in the chemical equation.
Approximate equilibrium constants may be derived emPloying molalities, mole fractions, partial pressures or the equivalent quantities that are usually measured.
However, the activities or fugacities must be employed to derive exact constants.
The Handbook of Chemistry and Physics, (59th edition, CRC Press 1978) at page D-203 lists dissociation constants for aqueous ammonia, tabulated as follows:

¦ material in the form of a liquid or spray, the concentration 10 ¦ of the ammonia control component can vary from about lS 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 tragacanth, 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.
When the ammonia control agent is used in a pelleted composition, qther components can include filler or roughase materials, such as straw, wood particles, alfalfa, ground peanut hulls, rice hulls, and the like. The filler component can vary from about 70-95% by weight of the total composition, but more preferably varies from about 85-92% by weight.
I _g_ 11539~
The ammonia control agent can be any of the compounds listed in Table I, preferably an alkali metal or alkaline earth salt, and most preferably sodium bi-sulfate. The ammonia control agent can vary from about 0.5 to 25% by weight, preferably from about 2 to 10% by weight of the total composition.
The pelleted composition can also include a binder material such as lignin sulfonate or other e~uivalent binder which does not react with the ammonia control agent in a manner which reduces its capacity to control the ammonia odor. The binder material can vary from about 0 to 5% by weight, preferably from about l/2 to 2% by weight of the total composition.
The pelleted composition can also include materials to increase its absorbency, such as natural or synthetic gums including guar gum, pectin, xanthan, locust bean gum, tamarind polyacrylamide and the like. The absorbent component can vary from .05 to 10% by weight, preferably from 0.5 to 2.5% by weight of the total composition, and should not be adversely affected by low pH's in the range of about 2 to 3.
A pelleting additive can also be incorporated in the composition to assist the pelleting process and improve the binding properties of the finished pellet.
A preferred pelleting additive is sold under the trade-mark "PEL-AID" (Uniscope, Inc., Johnstown, Colorado), and can be used in quantities up to 0.2% by weight, preferably from 0.05-0.1% by weight of the total composition.
! ms/-In pelleting the ammonia control composition, the size of the pellet is not critical. Generally, it can vary from l/8 inch to l/2 inch in diameter, and l/8 inch to l inch in length. A pellet 5/32 inch in diameter and about l/4 to 3/8 inch in length is preferred, due to the fact that this die size is commonly available to form the pellet. Longer pellets tend to break easier and produce more dust and fine particles.
Smaller diameter pellets slow down production. Large diameter pellets tend to crack open and produce dust and fine particles.
`l0 The geometry of the pellet is a matter of choice, and it can be spherical, rectangular, elliptical, square or cylindrical in shape.
In another variation, the ammonia control composition can be used in a fi~ely divided particulate form as a litterbox additive. The ammonia controI component is preferably sodium bisulfate or sulfuric acid. When sulfuric acid is used as the ammonia control component, it is preferred that calcium sulfate be used as the filler material.
Other filler materials include wood particles, diatomaceous earth, clay, straw, ground peanut hulls, rice hulls, alfalfa and the like. The particle si~e of the litterbox additive is generally a matter of choice depending upon the particularities of its application and whether or not the animal will come into direct contact with the composition. Generally, a particle size of 60-80 mesh (.250 to .177 millimeters) is adequate.
llS3956 The proportions of ammonia control component to filler material also will vary, depending upon whether the animal will come into direct contact 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 ammcnia control composition.
Therefore 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 bi-sulfate. In general, 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.
With animal litter, particularly that of cats and dogs, the use of sodium bisulfate has been found to be particularly effective in dealing with and removing the ammonia odor. A concentration of sodium bisulfate of 10~ by weight has eliminated the ammonia odor from the litter for up to eight weeks. As little as 0.5% exerts an effective control and up to 20% by weight is feasible.
The following examples set forth specific embodiments of the invention, and are not intended to limit the scope of the invention. All parts and per-centages are by weight, unless otherwise noted.
5 grams of sodium bisulfate were placed into a beaker. 3.75 grams of ammonium hydroxide were added gradually on a dropwise basis. During the addition, the ms/
`` 11S3~S6 beaker was frequently checked to detect the odor of the ar~monia by smell. No ammonia could be detected until an amount of ammonium hydroxide exceeding 3.75 grams, the stoichiometrical amount, had been added, thereby resulting in an immediate, irritating, strong ammonia smell.
In a procedure identical to Example 1, several other chemicals were tested for their ability to neu ralize ammonium hydroxide, thereby eliminating the odor of ammonia. In each instance 5 grams of the active chemical were used. In the data tabulated in Table III, each active chemical is listed next to the corresponding amount ofammonium hydroxide neutralized to the extent that no odor of ammonia was detected ~; mS/ ~
