  • Patent number: 11457606
    Abstract: Compacting expanded perlite fines in the presence of a clay and water, followed by drying, produces particles with low density, good integrity, and surprisingly higher absorption by volume than non-compacted expanded perlite or non-swelling clay. Furthermore, addition of a clumping agent to the compacted granules results in a clumping litter with low density, good integrity and comparable clumping ability to traditional clay clumping litter.

  • Patent number: 11457605
    Abstract: Litter formed of extruded pellets containing water soluble binder sufficient to self-clump when wetted producing pellet clumps having a clump retention rate of at least 90% and which shrink after clump formation during drying producing a clump pulls away from any contacting solid surface minimizing adhesion therebetween. Such clumps preferably also have a crush strength of at least 15 PSI when dry. Pellets preferably contain water-soluble binder formed of starch physically modified during extrusion that solubilizes when wetted to facilitate clumping while opening the interior of the pellet improving absorption capacity. A preferred litter is formed of a mixture of extruded pellets of different sizes producing litter composed of extruded pellets falling within a plurality of different size ranges with the smaller sized pellets being fines that cause horizontally extending clumps to form on top of the litter.

  • Patent number: 11440825
    Abstract: A waste treatment process utilizes a two-stage digestion process with a thermophilic digester, a heat exchanger, and a mesophilic digester. The pH of the thermophilic digestate is increased by removal of carbon dioxide with an air stripper, or by adding a pH increasing reagent upstream of the heat exchanger. The pH adjustment of the digestate protects the heat exchanger and downstream equipment and processes from struvite formation. A struvite reactor may be located in various locations downstream of the heat exchanger to produce a treated digestate or effluent that contains struvite, which can optionally be recovered for beneficial use.

    Abstract: A clump-forming hygiene granulate has individual granules, each granule having: at least one inner carrier grain of a porous, mineral, non-swelling carrier material; an intermediate layer mantling the carrier grain or grains including a mixture containing at least one powder of a non-swelling, mineral, porous material, and a gel matrix composed at least of starch that swells in cold water, and a hydrocolloid different from starch, which swells in cold water; bentonite powder or superabsorber meal disposed between the carrier grain or grains and the intermediate layer; an outer mantle layer sheathing the intermediate layer, having a mantle layer surface including a mixture containing at least a powder of a non-swelling, mineral, porous material, and bentonite powder; hydrocolloid gel that swells in cold water, disposed between outer mantle layer and intermediate layer; and hydrocolloid grains of a hydrocolloid that swells in cold water, distributed on the mantle layer surface.

  • Patent number: 8904963
    Abstract: The invention provides animal litters that have an increased absorption rate and methods of making and using such litters. The animal litters comprise one or more animal litter particles that have been produced by fragmenting extruded animal litter particles that have a film on the surface of the particle that adversely affects the absorption rate. The fragmenting exposes the interior of the extruded animal litter particles, which does not have this film, to the external environment and increases the absorption rate.

  • Patent number: 8733288
    Abstract: Animal litters and methods of making and using such litters are disclosed herein. The animal litters comprise (a) a plurality of absorbent particles comprising (i) a non-swelling particle and (ii) a clumping material coated on the non-swelling particle and (b) a plurality of one or more filler particles that are not associated with the absorbent particles. The filler particles provide additional functionality to the litters, e.g., controlling odor, absorbing moisture, releasing fragrance, controlling microorganisms, controlling dust, reducing density, reducing weight, and combinations thereof. The litters are made by producing the absorbent particles using conventional means and combining the absorbent particles with one or more filler particles that impart the desired characteristic to the litters.

  • Patent number: 8720375
    Abstract: The invention is directed toward a high performance clay-based animal litter that is comprised of a clay-based liquid-absorbing material, and at least one filler coated with at least one clumping agent. The particle size of the liquid-absorbing material is small and provides the litter with a “sandy” appearance. The high performance litter is found to be surprisingly effective in containing odors and reducing tracking and dusting. It does not contain foaming agents and/or acids to trigger foaming, and does not utilize foams to block odors.

  • Publication number: 20140000525
    Abstract: A clumping agent composition is provided that includes a pre-gelled starch divided to a starch size with at least 70% by weight of said starch being ?200 mesh. An polyoxygenated moiety is present and includes at least one of borax, bicarbonate, or aluminate. The starch and the polyoxygenated moiety combined to form the clumping agent composition with a rapid build of viscosity when wet. A litter is formed when the clumping agent composition is present from 1 to 10 total weight percent decorating the surface of a particulate. Divided carboxymethylcellulose is included in some embodiments along with the starch and the oxygenated moiety.

  • Patent number: 8601981
    Abstract: An animal litter with increased moisture retention and accelerated absorbency, a method of manufacture and method of use for indoor urine and feces disposal. An animal litter with a greater surface area and higher moisture retention intended for animals as small as mice, gerbils and hamsters, as well as larger domestic animals. The animal litter is a paper and wood composition treated with a surfactant, which increases moisture retention four to five times its weight.

  • Publication number: 20130319341
    Abstract: The invention provides low-dust animal litters made from one or more ingredients that function as an animal litter and one or more polyols that function to control dust in the litter. The low-dust animal litters are made by selecting one or more litter ingredients suitable for making an animal litter and combining the litter ingredients with one or more polyols, generally by applying the polyols to the surface of one or more ingredients before or during the process of combining the ingredients to produce the litter.
