Abstract: A sub-floor system for installing a monolithic slab using precast cementitious sub-floor panel sections. The panel sections are placed over the spaced-apart, parallel joists of the floor frame. Each panel has beveled edges which abut the beveled edges of its adjacent panels. The beveled edges between adjacent panel sections thus define a V-shaped seam area. Importantly, the panels are dimensioned such that the beveled panel edges running parallel to the joists are substantially on center over the joists. This allows for the insertion of anchors through the seam areas and into the joists. The anchors are only partially implanted into the joists so that the anchor heads project upwardly between the panel sections. The seam areas are then filled with an adhesive filler material, resulting in a high strength monolithic slab.

Abstract: Paper mill sludge is reclaimed and useful products produced therefrom. A predetermined amount of paper mill sludge is continuously discharged from a storage reservoir onto a mixer/conveyor to create a first reactant stream. A predetermined amount of calcium oxide is input into the first reactant stream from a calcium oxide reservoir. The calcium oxide and paper mill sludge are mixed as they travel along the mixer/conveyor to form a first intermediate mixture. After a time period sufficient to allow for the reaction of the calcium oxide and paper mill sludge, a predetermined amount of diatomite is added to the reactant stream from a diatomite storage reservoir. The first reactant stream, now comprising the first intermediate mixture of paper mill sludge and calcium oxide combined with diatomite, forms a useful, environmentally safe product.

Abstract: A floor dry material and method of manufacturing same in which waste cellulosic fibrous material, such as waste paper, is finely shredded after which any metal component is removed and the shredded material is then thoroughly mixed with a biodegradable surfactant, calcium oxide, and water until a temperature about 140.degree. F. to 150.degree. F. is achieved after which a natural citric-based solvent degreaser and a material selected from the group comprising silica diatomite plankton and non-swelling clay are added to obtain a finished floor dry material.

Abstract: A continuous flow process for treating waste cellulosic fiber or paper mill sludge wherein calcium oxide, silica and water are blended with waste cellulosic fiber or paper mill sludge such that a pH is reached of between 10.5 and 12 to provide a treated mixture. The mixture is agitated such that it is dried and fluffed for use as an environmentally safe filler material.

Abstract: A soil supplement and method of manufacturing same in which waste cellulosic fibrous material, such as waste paper, is finely shredded after which any metal component is removed and the shredded material is then thoroughly mixed with an agricultural wetting agent and a milk of lime until a temperature of about 120.degree. to 140.degree. F. is achieved after which a material selected from the group comprising silica diatomite plankton and non-swelling clay is added and the mixture is neutralized to a pH of about 7.

Abstract: A method of manufacturing animal bedding material in which waste cellulosic fibrous material, such as waste paper, is finely shredded after which any metal component is removed and the shredded material is then thoroughly mixed with calcium oxide and water until a temperature of the mixture of about 120.degree. F. to 140.degree. F. is achieved after which the mixture is neutralized with silica diatomite plankton or non-swelling clay in a ratio to obtain a final mixture having a neutral pH and drying the final mixture to obtain a product useful for bedding for animals.
